Lightened Flywheels for 2003-06 Nissan 350Z [Z33], 2003-07 G35, Nissan 370Z [Z34] & Q60 3.7
Don’t Miss this Upgrade When Upgrading or Replacing your Clutch – Get More WHP & Faster Response


Most enthusiasts know that replacing the OEM clutch with a high performance unit transfers more power to the ground, improving acceleration and performance. What not everyone realizes is that there are two sides to the clutch system besides the disc and pressure plate – the flywheel is just as important.

When it comes time to replace your OEM clutch, or if you’re thinking about upgrading to a high performance clutch in your Nissan 350Z or Infiniti G35, 370Z, G37 or Q60 3.7, you’re likely worrying about stuff like how many pucks your clutch has and its friction material – but you’re probably not thinking about your flywheel and really, missing this upgrade while you have everything apart during a clutch install is doing yourself and your Z, G or Q a disservice.


What not everyone realizes is that a lightened flywheel is one of the best modifications you can make to any manual transmission vehicle. So? The engine feels much more powerful and responsive- the whole car generally feels more lively. A lightened flywheel won’t ADD horsepower or torque, but rather, with it, you regain power and response that is normally consumed by drivetrain loss. By reducing some of the loss from the drag of the drivetrain on the engine, more engine power makes it to the wheels.

What does a flywheel do, anyway?
To understand why a lighter flywheel makes such a big difference in performance and response, you need to understand how a flywheel works. To put it simply, a flywheel is an energy storage device – the flywheel stores inertia energy. The purpose the flywheel in your car serves is smoothing out the fluctuations of torque on the crankshaft, as well as helping to maintain engine speed (RPM) at a designated level. In other words, the flywheel helps keep your engine from stalling as you feather on the clutch when taking off from a standstill, for example.

How does a flywheel work in practice?
Ever play with one of those “pull-back” toy cars as a kid? Those pull back toy cars rely on a flywheel to work. The wound up spring spins a flywheel, the spinning mass of the flywheel creates inertia, meaning the flywheel wants to keep spinning, thus keeping the toy car moving after the spring has delivered its initial thrust.

Imagine trying to run in work boots. Now  imagine trying to run again after changing the work boots for a pair of running shoes. Same idea. As your engine turns, it takes some energy to get the weight of the flywheel moving. In turn, the flywheel wants to keep moving, helping smooth operation and idle. The more mass a flywheel has, the more energy it will take for your motor to gain RPM. Most manufacturers opt for a heavier flywheel, the reason being that it makes the engine less likely to stall and much easier to use in stop-start traffic. When you reduce the weight of the flywheel, the vehicle feels more powerful as a result, because less energy is required to overcome inertia and get the flywheel moving. As a result, more of the engine’s motive power is transferred to the wheels, and since there is less weight holding back the engine, it will gain and drop revs more quickly as well.

There’s an anecdote that illustrates this brilliantly, funnily enough from an old Kung Fu movie, but hear us out here. So, there’s this climactic fight between two skilled fighters. The whole movie, one fighter is always seen wearing heavy ankleweights… but even with the weights on, he’s very quick, but his opponent is even faster. Just before the fight, to everyone’s surprise, the guy removes his ankle weights. With the resistance of the weights gone, the fighter has use of his full potential, giving him the extra performance needed to best his opponent. That’s effectively what’s happening when you fit an engine with a lighter weight flywheel.
Removing the unnecessary resistance unleashes your engine’s full potential.

Your Flywheel & Clutch Are Both “Wear Items”

Most people don’t consider that your flywheel wears out, just like your rotors wear away on your brake system. Not everyone realizes the flywheel’s friction surface wears out too, so some folks neglect to resurface or replace their flywheel when installing a new clutch disc, and that’s really only doing half of the job. The clutch grabs onto the flywheel’s face, wearing it out as well as the clutches’ friction material, so like your brake pads, rotors and clutch, it too is a wear item and should also be serviced whenever you’re replacing the clutch.

AASCO Billet Flywheel

On the Nissan VQ engines used in manual transmission-equipped 350Z, 370Z, G35 , G37, and Q60 3.7 the difference is especially noticeable. In the 370Z and its VQ engined sisters, the OEM flywheel weighs in at a whopping 25-26lbs – by contrast, the STILLEN Flywheel for Nissan 370Z and Infiniti G37/Q60 tips the scales at only 14.25 lbs, a difference of more than 10lbs. For the earlier Z and G models, the STILLEN Flywheel for Nissan 350Z / G35 offers similar weight reduction.

As the flywheel turns, centrifugal force and inertia make the flywheel act as if it is many times heavier than it is, which holds your engine back significantly.



As an alternative, the ACT Streetlite Xact Flywheel for 370Z, G37 and Q60 3.7 is slightly heavier at 17.4lbs, and that’s still a big improvement over the stock 25lb part. The additional mass makes it just a bit friendlier on the street while still offering the benefits of a lightweight flywheel, and it’s a good bit less expensive at just $366 (as of press time).

The tradeoff is that this flywheel is non-serviceable, so once you’ve worn it out, you’ll need a new unit (as opposed to resurfacing or replacing it), and of course, it will be a little slower to drop or gain revs compared to the STILLEN unit because the ACT unit is 3lbs heavier, but it’s still a significant improvement over stock.



Face to Face: The black disc on flywheel is what makes contact with the face of the clutch

The clutch and the flywheel are as critical to each other as peanut butter and chocolate are to a Reese’s cup – it’s not a Reese’s without both, so be sure to service your flywheel whenever you replacing the clutch. Doing one without the other is kind of like replacing just your brake pads without servicing the worn out rotors. While yes, it’ll bolt together if you skip replacing the rotors during a brake job or resurface the flywheel when doing a clutch, it’ll ‘work’, but it won’t perform as well as it should or could.

More Affordable Than You Think

The other thing is, the 370Z, G37, Q60 3.7 and late-production 350Z models use a dual mass flywheel. What this means is that the average machine shop cannot resurface it, it has to be sent out to a specialty machine shop, meaning that for many people, an expensive OEM replacement flywheel is the only viable option.

Trouble is, a replacement OEM flywheel is a whopping $1200 USD at press time. By comparison, the STILLEN flywheel is less than half that at $535 USD (at press time), saving you nearly $650. What’s unique to the STILLEN Lightweight Flywheel for 2008-10 Nissan 370Z is that unlike virtually every other lightened flywheel available for these cars, the STILLEN flywheel is rebuild-able. This means that when its friction surface wears out, you’re only buying a $125 replacement component. With a flywheel that is not rebuildable, you’ll be stuck buying a whole new flywheel when it wears out.

The reality is, if you’re upgrading or replacing your clutch, you’re already doing the majority of the labor needed to install a lightweight flywheel. That makes a lightweight flywheel the perfect “While I’m At It” mod.

For your convenience, STILLEN also offers a flywheel and clutch package, the STILLEN High Performance 350Z / 370Z / G37 Clutch / Flywheel Combo, which includes the STILLEN Flywheel, an ACT Clutch / Pressure Plate and of course, a new Pilot Bushing with clutch alignment tool. Available for $989.50 (as of press time), this package saves you some green when compared to buying the included items one-by-one.

We’ve covered the performance benefits and potential cost savings, there is one more CRITICAL item you really should replace while you’ve got your car taken apart, and not replacing this one little part can really bite you in the behind later on, and take your Z, G or Q out of commission when it goes.


ZSpeed Performance Slave Cylinder GRAYED
One of the notorious issues specific to the 370Z, G37 and Q60 3.7 is the clutch slave cylinder. The OEM Nissan unit is a rather brittle little plastic part – and ludicrously prone to failure.

The Problem
If you’re installing an aftermarket performance clutch in your 370Z or G37, it is a GUARANTEE that your OEM Nissan clutch slave is going to fail on you in the very near future. We don’t say that kind of thing lightly. The OEM clutch slave might survive with a stock clutch, but it can’t manage an aftermarket clutch. Yes, you can use an OEM Nissan replacement for your failed clutch slave, but remember, the design and materials are still the same, which means the replacement will also inevitably fail too.

The frequency of failure isn’t an exaggeration, either. The OEM slave really is that bad on the 370Z, one only needs to google “370Z problems” to see just how frequently the CSC’s fail, and we’ve even seen it firsthand on customer vehicles – in one case, the customer opted to skip the clutch slave when installing a new clutch disc despite our warnings, and unfortunately, within 2 months the OEM CSC unit failed, just as we had cautioned it would. The customer’s 370Z had to be taken apart all over again to replace it, and when you consider paying for the labor of dropping a transmission twice, that’s a rather pricey gamble.

The Solution

ZSpeed Performance Slave Cylinder MAIN
This brittle and leak-prone plastic OEM CSC was such a nuisance, it drove ZSpeed Performance to develop their heavy duty ALL-METAL Concentric Clutch Slave Cylinder for the 370Z and G37 (and late 350Z’s with the HR engine), and given the ridiculous failure rate, the experts at STILLEN highly recommend ZSpeed Performance’s Heavy Duty Clutch Slave as a part of any G37 or 370Z clutch service. On the earlier 350Z and G35, the slave was serviceable from the outside of the transmission… on the 370Z and G37, you’ve got to do all the work you’d normally do while replacing the clutch in order to replace it.  We STRONGLY recommend installing this upgrade with any clutch replacement – take our word for it, you’ll regret it later if you skip the slave when replacing or upgrading your clutch.

A replacement OEM plastic clutch slave from Nissan is around $125, while the ALL-METAL Heavy Duty Zspeed Clutch Slave is a bit spendier at $325 (as of press time), but consider, for that additional cost, you’re getting all metal construction. That means you have peace of mind to drive and enjoy your car, as you’ve replaced the ticking time bomb of failure with a more durable version that will serve you reliably for many miles to come.

We realize we’re beating a dead horse a bit here, but seriously, save yourself the tow truck, the labor and the heartache and replace the slave while you have everything apart. After all, it’s not a matter of if, but WHEN your clutch slave is going to fail, and it would suck to have to pay for the labor twice. You’ll thank us later.


Is a Lightweight Flywheel Street-Friendly?
The caveat to a lightweight flywheel is that going too light can cause driveability problems and make stop-start traffic challenging. The STILLEN Flywheel is designed with streetability in mind, offering both significantly enhanced performance and response while also keeping enough mass to ensure the car won’t stall out in stop/start traffic like it may with an ultra-lightweight RACING flywheel. The experts at STILLEN have spec’d out a flywheel with a great balance of weight reduction and real-world usability.
We do want to note here that a lighter flywheel will cause some light gear chatter- but pretty much any flywheel other than the OEM unit will chatter, too. If mild gear chatter is an issue for you, resurfacing or replacing your OEM flywheel could be a possible alternative option.



In short, the STILLEN flywheel offers a major improvement in performance and response you’ll really feel on the ol butt-dyno and it’s less than half the price of a replacement OEM flywheel. Even if you add in the Zspeed Clutch Slave, you’re still spending hundreds less than an OEM flywheel for an increase in performance and response that few other mods can offer.

STILLEN is excited to announce the launch of our complete line up of products for the 2018 INFINITI Q60 at the 2017 SEMA show.

The INFINITI Q60 redsport is a very exciting car as it brings performance back to the INFINITI marque.  Featuring a potent 400 horsepower twin turbo V6 badged the “VR30.”  This car offers the driver an exhilarating experience and inspires the driver to push the car aggressively.

STILLEN has been involved in performance parts for off-road trucks, supercars and street performance cars of a variety and makes and models, but STILLEN is perhaps best known for our experience in tuning NISSAN/INFINITI vehicles… we’ve been involved with developing performance parts for Nissan (and later Infiniti) for over 30 years now.  When the opportunity came to work with Infiniti on this platform, we jumped at the chance and let our engineers run wild.

To kick things off, we took a look at how we could beef up the car’s performance.  Our engineering team immediately began dissecting the air intake system to study it and determine how we could optimize airflow. While the engineering team was busy with figuring out how to get every last pony out of the intake, our fabrication team were hard at work under the car, reviewing the exhaust routing, tube diameter, configuration of the system and the construction of its muffler, all in order to see what gains could be made.

STILLEN INFINITI Q60 REDSPORT 400 SEMA 2017 3R1A0019 Cover off

After going through more than 20 prototype intakes trying to achieve our goals, our induction specialists produced a Q60 Intake design that yielded a huge gain of over 20 horsepower at the wheels, and that’s without the need for further tuning or any modifications to the vehicle. Not every ‘high flow’ intake on the market works with the OEM ECU map, so making sure our intakes benefit the car with the stock tune is a high priority for our design team. The end result is what you see above – the urethane airboxes offer a significant advantage over an exposed conical filter, as the airboxes ensure that the intakes are drawing in only cool, outside air, rather than sucking in hot air from inside the engine bay (which robs you of power). Designed as a complete solution, the STILLEN Cold Air Intake for 2017 Infiniti Q60 comes complete with silicone couplers, CNC machined and tig welded aluminum MAF tubes as well as poly-urethane air boxes to keep the engine fed with cooler air, helping to deliver maximum power output.


Turbo V6 engines are notoriously difficult to get the sound “just right.”  In the end, our team was not satisfied with any of the common mufflers we could source “off the shelf.”  The only option was to build our own.  So, we engineered our own mufflers, manufacture them in house, and pack them with a high temperature ceramic wool.  These tuned mufflers truly allow the heartbeat of the car to be experienced. The final exhaust design was selected after 15 different prototype systems were rigorously tested on our Dynojet chassis dyno.  It took quite a while to determine what the engine wanted in order to produce the most power across the entire powerband.  The end result is a tuned Y pipe, leading to a single mid pipe which branches back into a dual outlet exit.


With the performance parts development underway, now it was time to address the exterior styling.  The Q60 is a fantastic looking car straight out of the factory, but like a nice tailored suit, it can look even better with the addition of the right accessories. To bring out the car’s flowing lines, we opted to wrap the car with a red chrome wrap.  The brilliant luster of the red chrome accentuates all of the angles and curves of the body of the car and truly ‘makes it pop’. The Q60 has a very organic, free flowing design, and the hyperreflective red chrome shows off these daring curves and deep creases exceptionally well.  Like any car, we felt it could be a bit more aggressive and could do with some aero styling to really accentuate the curves the car comes with. The STILLEN design team then set to work shaping a Front Bumper Splitter featuring STILLEN Front Bumper Splitter for 2017 Infiniti Q60 – (with Winglet Extensions). With the front end spiced up to our satisfaction, we shifted our attention over to to the rear of the car, the STILLEN craftsmen then created a set of side splitters and rear spats to suit the aggressive feel we were going for.  Both of these parts were custom fabricated exclusively for the STILLEN Q60.


Finishing off the ground effects package, STILLEN designed a Rear Diffuser for the Red Sport V36 Infiniti Q60 with a set of aggressive air channels and openings for a larger-than-stock dual exhaust.  The STILLEN diffuser for Infiniti Q60 is no “one off” for a show car – this part is a production item you can purchase and install on your own Q60, along with the rest of the aero suite, including the STILLEN front splitter and winglets. While these days the majority of aftermarket manufacturing seems to be done overseas, but at STILLEN, we make all of our products right here in the USA. Every single STILLEN aero or appearance upgrade, intake and exhaust system is designed and manufactured in the USA, right here at STILLEN headquarters in Costa Mesa, California. Not everyone realizes that here at STILLEN we fabricate pretty much everything in-house,  exterior parts, intakes, exhausts, suspension bits — our CNC machines, benders, welders and a team of experienced and talented craftsman makes it possible to do everything here. Now that we had the ground effects completed, the team still felt like our Q was still missing something.  The rear end still lacked something, so next, the STILLEN artists then turned their attention to the rear spoiler.  The initial idea was a simple, clean spoiler that would added a bit of height to the deck lid.  After a few design studies, the team decided to step it up and came up with something that would compliment the dynamic lines of the Q60’s design, and created a custom hand crafted rear wing that completes the car and ties in beautifully with the overall design concept.


With the power and exterior styling completed it was time to focus on supporting all of that extra power and downforce.  To do so, the STILLEN team partnered with RSR suspension, who used the STILLEN Q60 to develop and prototype a set of coil overs that are truly incredible.  One difference that sets STILLEN builds apart from other SEMA showcars is that our cars are built to be driven. Our Q60 Redsport is no trailer queen – this car was driven to the show and then driven home.  Since this car would be seeing hundreds of miles of actual road use between STILLEN HQ in Costa Mesa and Las Vegas, it was vital that the car not only look good, but could also retain its handling performance. The team at RSR hit another home run with the RSR Coilovers for 2017+ Infiniti Q60 we had fitted to the car – we really enjoyed these dynamic coil overs.  The ride quality is fantastic when cruising on the freeways and the car carves through the canyons with ease.


To make sure that the alignment was correct after the coil over installation and subsequent ride height lowering, SPC suspension provided a complete set of adjustable suspension including front upper control arms and SPC Suspension Rear Camber, Toe and Setback links for 2017 Infiniti Q60.  By installing the adjustable SPC suspension the STILLEN technicians were able to precisely dial in the alignment ensuring excellent handling characteristics.


To finish off the performance parts AP Racing by STILLEN big brake kits were installed on the Q60.  This brake package consists of the patented AP Racing World Radi-cal II calipers along with the patented J hook rotors.  For the front end, red 6 piston calipers were selected and matched with 390mm AP Racing rotors.  Matching the rear to the front required a set of red 4 piston calipers paired with 370mm AP Racing rotors.  The combination of the front and rear kits have proven to greatly reduce stopping distances, improve heat cycling longevity and stability under heavy load.


No car would be complete without the right wheel and tire package.  Wheels are one of those items that can make or break a car.  For years STILLEN has chosen VOSSEN Wheels for 2015+ Infiniti Q50 / Q60 and NITTO tires for their vehicles.  On this car though they wanted something a little different.  To accomplish this the STILLEN team selected the Vossen X Work line of wheels.  Particularly, the VWS-1.  Work wheels is a leading Japanese manufacturer of high end wheels and the collaboration between Vossen and Work has resulted in a melding of Japanese technology with American style.  These two piece wheels feature a high luster polished lip with a matte  gunmetal center and polished anodized barrel.

NITTO tires have been the preferred tire for STILLEN for many years.  Offering a wide range of tire selections for everything from race cars to passenger cars and even offroad vehicles.  For the STILLEN Q60 project STILLEN selected the INVO series of tires.  INVO tires are designed specifically for the luxury sports car enthusiast.  They offer excellent performance and grip without sacrificing comfort.


We’re thrilled with the end result of how our 2017 SEMA project came out – the team here at STILLEN feels that the Q60 we put together strikes the perfect balance between high end street luxury, with design inspired by our race-winning heritage tempered with elegant style.

STILLEN Vice President Kyle Millen had this to say of the project:
“The STILLEN Infiniti Q60 project car is one of my favorite cars out of the many projects we have created.  The team at STILLEN did an amazing job and made a car that is truly one of a kind.  From the work of the body craftsmen, the engineers and fabricators working tirelessly on the performance parts, I am extremely proud of the effort put into this car and the end result.”

Body Styling and Lowering are on the Rise

It’s an unspoken rule among auto enthusiasts that every car looks better with a set of gorgeous wheels and lowered suspension. Therefore, it’s not surprising that with this rise in sales, there is a corresponding increase in aftermarket upgrades purchased. To give this car that oh-so-desirable lowered stance, a set of RS-R Lowering Springs for 2009+ Infiniti Q60 were fitted, offering a 1.2in drop up front and a 1.0in drop at the rear for a sleek yet understated look. A slick set of semigloss black Vossen Wheels completes the aesthetic.

We spoke to Infiniti of Melbourne’s Parts Department manager, Luke Degraff, who shared some of his observations.

“The increased sales of the Q60 coupe, along with its sedan sibling, the Q50, have led to an increase in aftermarket parts sales, especially the STILLEN Unpainted Front Bumper Splitter for 2017 Infiniti Q60 [V36] and the STILLEN Rear Valance Diffuser for 2014-2017 Infiniti Q50 [V36]. A good number of customers have also chosen to lower their new Q50 or Q60 with a set of RS-R Lowering Springs for 2009+ Infiniti Q60 [V36] RWD (N120D). We chose Vossen Wheels to complete the showroom model. The presentation has been very well received!”

STILLEN Short Ram Intake for the Turbocharged Infiniti Q50 Sport and Red Sport 3.0T


STILLEN Hi-Flow Intake w/ Dry Filter for 2016-2018 Infiniti Q50 + Q60 (402856DF)


Infiniti breathed some forced induction life into the Q50 Sport and Red Sport models with the inclusion of its all new, twin turbocharged VR30DDTT V6 engine. Conservatively rated from the factory with 300 horsepower (in the Sport) and 400 horsepower (in the Red Sport), these new “Q’s” make decent power off the showroom floor. However, like any turbocharged engine, reducing air flow restrictions allow a turbocharger to spool up more quickly while efficiently generating boost pressure. This translates into improved response, greater incremental gains and oftentimes, more peak power.


As a longtime specialist in the world of Nissan and Infiniti, STILLEN takes great pride in the engineering of its products. Having seen the performance potential in the new 3.0-liter twin-turbocharged V6, our engineers set out to develop an intake system that produced the greatest performance gains without triggering the dreaded “Check Engine Light” error or requiring a custom tune.



Unlike any other intake manufacturer, STILLEN’s longstanding relationship with Nissan helped to facilitate a genuine Nissan factory CONSULT diagnostics computer. Monitoring data channels that most in the aftermarket cannot, STILLEN engineers tested more than 20 different intake designs, evaluating numerous variables and noting the effects on specifics such as fuel trim, velocity and temperature, to name just a few. While the sheer number of prototypes might seem like overkill, the data collected enabled STILLEN to optimize the intake design for output and presentation.


INTAKE (As tested on a 2016 Q50 Sport)

Peak Power: 293.15 whp @ 5,331 RPM

Greatest Incremental Horsepower gain: 20.98 whp @ 3,244 RPM

Q50 Intake WHP

Peak Torque: 289.87 lb-ft @ 5,300 RPM

Greatest Incremental Torque gain: 33.71 lb-ft @ 3,256 RPM

Automotive customization is really starting to hit the mainstream more often these days. You used to walk into a dealership, pick your color and a few options and that was the extent of the customization available at the dealer. However, things are changing, and for the better. More manufacturers and dealerships understand that consumers want their vehicle to be unique and reflect their personality. Automakers now offer more trim packages, color combos and more elaborate accessories than ever before. While this has satisfied a number of buyers, some dealerships realize that their customers wanted more.

Funding to modify a brand new vehicle often poses a hardship, as consumers generally spend a good amount on the down payment in order to make the monthly payments more palatable. Often times, this doesn’t leave a lot of cash for customization. Bennett Infiniti of Wilkes-Barre, PA understood the dilemma and decided to offer its customers the opportunity to drive off the lot with a customized ride. When this dealership modifies the car for you at the time of purchase with parts sourced directly from STILLEN, the cost can be rolled into your financing. This means you can add some nice modifications for approximately $40-$120/month (amount varies depending on cost of parts and labor).

Here is a great example of a modified Q50 Red Sport AWD that Bennett Infiniti put together. They installed the STILLEN Front Splitter, Side Splitters, Rear Diffuser and Wing to really give the Red Sport a more appropriate and aggressive appearance.

2017 Q50 Red Sport AWD STILLEN

The dealership informed us that the modified cars on the showroom floor always garner the most attention and it’s easy to see why. So next time you are in the market for a new car and want it modified, you know where to look!

The VR30DDTT is an impressive motor. It is underrated from the factory as we have seen with dyno testing. The Hi-Output version is rated at 400 hp and 350 ft-lbs at the crank and the Low-Output version is rated at 300 hp and 300 ft-lbs at the crank. We have consistently seen ~375 whp and ~350 wtq from the Red Sport Q50’s and Q60’s and ~300 whp and ~290 wtq from the “300 hp” versions.

That being said, everyone is still excited to see what these motors can do. With factory forced induction there is often a ton of room for gains when you simply tune the car and crank the boost up. Now there is a lot to consider before assuming power gains by simply increasing boost and tuning. So strap on your thinking caps and prepare for the math!

The factory turbos on the VR30 are produced by Honeywell-Garrett. The model of the turbo is MGT14446LKSZ. We could talk technical specifications*, but in the end let us just say the turbos are small. What is more important is we have the turbo map for the MGT1446 turbo. This has allowed us to see what efficiency range the turbos are operating under stock boost, as well as the limits of the turbos when it comes to boost levels and power gains.


We can see the VR30 Red Sport (400) boost curve looks something like this. With this knowledge, we can run a series of calculations to see the efficiency of the turbos throughout the RPM range.


For everyone who would like to do the math themselves the basic formulas are as follows.
Cubic Feet/Min:

Corrected Air Flow (CAF) lbs/min:

Pressure Ratio (PR):


So for stock boost our table will look like this:
*we use 1.5 liters as displacement as only half the motor feeds each turbo.

Q50 Red Sport – Stock (14.5 PSI)

Utilizing the same formula and increasing boost, we made a graph then overlaid onto the Turbo Map. We included the Low-Output graph for reference as well.


You can see that even at stock boost (for the Red Sport) the turbos are off the efficiency island (below 60%) post 5750 RPM. So what happens as you move off the island? As turbo efficiency goes down you begin to generate more and more heat for the given boost pressure.

If you look at the stock dyno sheet, you can see where the horsepower curve begins to flatten out at around 5000 RPM. We have also seen with an aftermarket exhaust and secondary cat deletes the gains past the 5000 RPM area are far less significant. This can pretty much all be attributed to the turbos.

2017 Q50 Red Sport Dyno

2017 Q50 Red Sport 3.0tt Stock Dyno Sheet

We went ahead and also did graphs of increased boost pressure following the factory curve up to max pressure. We assume the lower boost pressure below 4000 RPM is to keep the torque under control for driveability’s sake.


Looking at the chart, one can see that as you increase the maximum boost levels you move out of the efficiency island very quickly. At 17 PSI you move below 60% efficiency at 5500 RPM which is not much worse than stock. However, once we get into the 19 PSI Range you can see us leave efficiency by 5250 RPM. On top of that we are moving over 23.6 lbs/min (or 342 CFM) at 6250 RPM very far outside of the efficiency island. This puts a lot of stress on both the engine and turbos.

So aside from changing the turbos (which there are no upgrades available at this time), what can we do to safely increase power? We believe it is unwise to spin these turbos much past 17 psi in search of a lot more power (at least above 5000 RPM). So with a moderate increase in boost pressure, the name of the power game will be EFFICIENCY (yes I’m sure you’re tired of reading that word).


With any factory setup, there are going to be restrictions. Some are cost related, some are emissions related, and some are Noise/Vibration/Harshness (NVH) related.

We already know the first restriction point lies in the intakes. Factory intake systems are the first point of emissions and sound control on a car. The STILLEN intakes have already shown impressive gains in the mid-range powerband. This makes sense as the highest efficiency range of the turbo at factory boost levels (and even elevated boost levels) will be in the 3250-5000 RPM range.

The factory exhaust system on the VR30 powered cars is definitely a bottleneck as well. We know the secondary catalytic converters narrow down to 1.5 inches (diameter) just before the cat-back. On top of that the factory cat-back exhaust is a mere 1.75 inches (diameter). Now removing the factory catalytic converters is frowned upon by the EPA, so we can’t recommend changing those out. However, a cat-back exhaust is perfectly legal and voids no warranties (which we are sure most of you know). On top of giving the Q50 & Q60 the exhaust note it deserves, the cat-back greatly increases the efficiency of the turbos by reducing back pressure. This reduction in back pressure reduces the resistance on the turbines and in turn allows them to spool faster and easier. This means for the same given turbine speed, you are able to create more boost (or the same boost) with less heat.


While heat is necessary for an engine to run properly, too much is definitely a bad thing. While on a naturally aspirated motor, a cooler intake charge can greatly improve performance. Forced induction doesn’t yeild as impressive of results. Why is this? The air pulled through the intakes enters the turbo which compresses the air. The compression of air causes an increase in air temperature (see Boyle’s Law and Charles’ Law) which is problematic for internal combustion engines. With most forced induction setups there is an intercooler (or aftercooler) which is located between the turbo and the lower intake manifold. Said intercooler can be either an Air-to-Air or Air-to-Water system. The VR30 uses a pair of Air-to-Water intercoolers. The heat exchanger for the intercoolers (how the heat is removed from the system) is located in front of the radiator behind the grille.

The Red Sport version of the Q50 and Q60 both come with two waterpumps (push-pull) to increase cooling for the intercoolers. This makes sense as the Red Sport boost levels create a lot more heat at higher RPM than the 300 hp version. Knowing that many people will be increasing the boost of both models, everyone could definitely benefit from more cooling. While the intercooler units themselves would be difficult to upgrade since space in the engine bay is quite limited, the heat exchanger up front has some room to grow. Increasing the size of the heat exchanger does two things: allows for more heat to be extracted from the hot fluid, and increases the volume of fluid which increases the overall thermal capacity of the system. While this isn’t the ultimate solution, it would make running higher boost levels (17-18 psi) safer as well as reducing potential heat soak after prolonged aggressive driving.


While there is still a lot of exploring to do when it comes to tuning, there are several things we can see just by looking at the turbo map and dyno sheets. Your biggest gains will all be in the mid-range (2500-5000 RPM) with the stock turbos.

Based on the turbo map, tuning to 18 PSI from 4000-5000 RPM puts you in a very ideal efficiency range for the turbos. Now dropping the boost after 5000 RPM is important as holding too much boost is not ideal for the motor or turbos, but also won’t gain much additional power. This fine tuning of boost pressure adjustment is made easier by the factory electronically controlled wastegate actuators.



While we are still waiting on the tuning companies we work with to release official software, we are confident it won’t be much longer. You can bet we are just as anxious to start tuning these cars as you are, but with any new platform the best products take a little time to develop.


Although we probably won’t be seeing any 600 whp Q50’s or Q60’s without bigger turbos, there is still a lot of potential even on the factory units. Needless to say, we are all working on more ways to make power with this platform. STILLEN is about to release our new intake system for the 3.0t Q50 & Q60 along with our Cat-Back Exhaust for the 3.0t Q50!  Our engineering department has done a lot of work on these products and designed them with the factory setup in mind as well as future upgrades. Stay tuned (pun intended)!

2016 Infiniti Q50 3.0t Red Sport

The End of an Era Begins

With the introduction of the Q50 Twin Turbo and 2.0 turbo, 2016 marks the beginning of the end for the now famous Nissan VQ family of engines.

For nearly two decades, the Nissan V6 engines have been based on the VQ platform. These engines have been widely revered as powerful, fun, and innovative V6 mills with a distinctive sound – some would argue the “best” sound on the market.

STILLEN has always been fond of the VQ and its many variants; VQ35, VQ35DE, VQ35 rev-up, VQ35HR, VQ40 (found on the mini-truck and compact SUV line), and of course, the swan song VQ37 featuring Nissan’s progressive VVEL technology.

Nissan Returns to Its Roots

With deep respect and fond appreciation we say good-bye to the VQ. Now, we’re ushering in a new era by going back in history about 25 years.

Sound weird?

To our eyes anyway, Nissan appears to be returning to its performance roots. Long time Nissan fans know that the epitome of a performance Nissan engine is the VG30 3.0 liter V6 engine found in the Z32 chassis Nissan 300ZX. These cars were feared and respected in their time and are now considered timeless classics.

The latest excitement surrounding NISSAN power plants is the new VR30 3.0 liter V6.

See the resemblance?

The VR30 comes in two flavors, 300HP and 400HP. Needless to say, here at STILLEN we can’t wait to work on these engines.

However, it isn’t the only interesting new turbo engine available from Nissan/Infiniti.

The new Q50 is already available with a 4 cylinder turbo engine sourced from Mercedes.

Which leads us to the question…

One Turbo or Two?

Contrary to all the talk about the Infiniti Q50 and the all-new VR30 Twin Turbo, there’s been nothing but crickets about the Q50 2.0 Turbo that recently hit Infiniti showrooms.

Makes us wonder: is two the minimum number of turbos required to generate online chatter these days? Or is it more about engine displacement? Both?

Regardless, as usual the car with the smaller engine gets ignored. Here at STILLEN, we love underdogs because they usually embody the kind of performance challenge we love to take on.

And we know there’ll be plenty of enthusiasts who will pick up a Q50 4-banger and promptly begin to modify it.

So color us inspired!

Your 15 Seconds of Fame

Everyone dreams of owning that 500+ horsepower monster…the one that gets you daydreaming. You know the scenario: that magical day you line up on a Ferrari and live out everyone’s Fast and Furious fantasy.

The one where you:

  1. Win the race
  2. Shame the dude
  3. Get the girl

Ahhh yes…

Now that you’ve taken a second to imagine that scene from the movie, let’s return to reality. Because of real life concerns like budgets, insurance, significant others and gas mileage, lots of people will be purchasing the 2.0 Turbo version.

You know..the model that only has one turbo.

“One turbo? Old school, Bruh”.

Nah…the truth is, turbos in any quantity are back to stay and will likely usher in a golden era of automotive performance that we last enjoyed in the turbocharged 90’s.

No Replacement for Displacement?

Sure, bigger displacement motors will always be the dominant power plants in regards to hop up potential. There truly is no replacement for displacement after all.

And there seems to be a particular stigma in the Luxury Sport Sedan/Coupe scene about small displacement motors. While many owners now equate larger displacement 6 cylinder engines with luxury, let’s not forget that these 4 cylinder turbo motors aren’t that different that those found in other sporty cars.

A Weighty Decision

The weight differential between “pure” sports cars and “luxury” sport cars is less than you might think. For example: Subaru WRX – 3400 lbs, Audi S3 – 3400 lbs, Mitsubishi Evo – 3500 lbs. Granted, the Q50 2.0t weighs in around 3700 lbs. And yes, those other cars come from the factory with a lot more power.

However, there are plenty of indications that this engine is very capable of respectable output. We already know some versions of this motor (sourced from Mercedes) make 241 hp from the factory. The 208 hp version has been tuned to around 260 hp (and 302 lb-ft torque) with the stock turbo.

Needless to say, it appears there’s room for growth. If it’s possible to get the 2.0t into the 300 crank horsepower range, it will definitely be a blast to drive. It’d pretty much erase the 200 pound penalty and deliver all the real world benefits of a smaller displacement engine (insurance, gas mileage, happy girlfriend, boyfriend, spouse, etc).

Go Fast Bits – Developing Q50 Turbo Aftermarket Parts

STILLEN has already confirmed fitment of our body styling polyurethane parts (Splitter, Diffuser, Side Splitters, Roof Wing, and Deck Wing), Axle-Back Exhaust, and Rear Sway Bar. We have a cat-back exhaust in development and more goodies on the testing bench.

Handling wise, our friends at RS-R already have lowering springs and coilovers done.

So the power, performance and style parts for the 2.0t Q50 are already on tap and ready to quench your thirst.

Driving Impression: Torque to the Rescue

When Infiniti released the Q50 back in 2013 (as a 2014 model), the enthusiast community was impressed by its styling, comfort, and performance. The tried and true VQ37 provided ample power for a bit of fun and that refined feeling. It was only a matter of time before Infiniti followed the market trend and began spec’ing a small displacement turbo engine for the base model. Like most people, we thought this was a bit of a travesty (we’d grown rather fond of the raspy V6).

Now that we finally got a chance to drive the 2016 version of the small displacement Q50…it’s..not so bad.

At the bottom end, horsepower feels a bit anemic, but a dose of torque on the low end of the curve helps move things off the line.

At the other end of the spectrum, the car definitely lacks the top end power we were accustomed to with the previous engine. Once you pass about 5K rpm it feels like the motor is being reined in. The power stops building and the acceleration falls off a bit.

It isn’t terrible, but it’s a little disappointing to say the least.

Good News Travel Fast

The good new is, our initial testing with exhaust parts has definitely yielded improved feel in top end power. This hints that the car will be very responsive to mods. Who knows…maybe a STILLEN modified 2.0t will end up being faster than the VQ37 equipped Q50’s. Time will tell.
