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!

Small but Mighty? The Infiniti 2.0t engine has plenty of promise!

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.

infiniti q50 2.0t engine

The Infinity 2.0t looks docile. Looks can be deceiving though.

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.

The 2016 Q50 looks the business in STILLEN’s favorite color



This could be a common view of a STILLEN modified 2.0t. “Buh-Bye Mr. 3.7!”

With Nissan/Infiniti recently announcing the release of their new Twin Turbo V6, we wanted to take a closer look at this motor and what is means for the Aftermarket industry and Automotive Enthusiasts.

NASHVILLE (Dec. 15, 2015) – Infiniti’s new compact, lightweight 3.0-liter V6 twin-turbo engine is the most advanced V6 engine that the brand has ever offered, striking an ideal balance between drivability, efficiency, and performance. The 3.0-liter V6 twin-turbo is an all-new engine from the new and exclusive VR-series powertrain family, born out of the brand’s longstanding heritage of V6 powertrain production. The new engine has been engineered to empower the driver and offer increased power and torque and higher levels of efficiency than any comparable predecessors from the company.

The all new ‘VR’ 3.0 Liter V6 Twin Turbo motor is touted by Nissan/Infiniti to be the most advanced V6 they have ever offered. With features like Direct Injection, high efficiency turbos, electronic wastegate actuator, etc, there is a lot to talk about.

Let us start with the pros of this engine when thinking about aftermarket tuning and modifications.

  • Twin Turbos…I repeat…Twin Turbos! Some of the most exciting times in the Tuning Scene were in the 90’s when most of the big import sports cars featured factory turbos. When a car comes factory equipped with a turbo charging system, many of the inherent challenges are solved. Is the engine bay properly designed to manage the heat generated? Is the engine able to handle the pressure of forced induction? Is the engine bay big enough to house turbos? All of these potential hurdles are instantly removed because the turbos and infrastructure are already there.
  • Direct Injection! Direct Injection systems have much higher flow ratings than they use so when adding power there is no need to upgrade the fuel system (to a point).
  • Electronic Wastegate Actuator. In the past the turbo wastegates were controlled by pressure and dictated by a boost controller. With an electronic wastegate actuator, you can control the wastegate and the amount of boost you make more accurately and variably. Nissan is using this to make more power on the 400 hp variant of this motor, and we should be able to have a lot of fun with it once we have an ECU control. If it is not possible to control the wastegate through the ECU there is always the option of using an aftermarket diaphragm style wastegate actuator and using a standalone boost controller. If and when ECU control is available it will be the most cost effective and best option.
  • Oxygen Sensor & Exhaust Pressure Sensor. Oxygen (O2) Sensors are obviously a crucial part of tuning. However, on forced induction motors the way O2 sensors record data is different because of the change in air properties under pressure. The addition of an Exhaust Pressure Sensor allow for more accurate scaling, tuning, and data in regards to the gases coming out of the cylinders. This means better and safer tuning when adding power.
  • Square Engine (1:1 Bore to Stroke Ratio). Utilizing a 86mm Bore and 86mm Stroke the new VR Motor is a “Square Engine”. The Square design gives a balance of Torque and Horse power (Torque is more dependent on total displacement while Horsepower is more dependent on valve area). With Square motor, you also get a smoother transition between the torque and horsepower power curve.


Other nice things we have noticed about the new VR 3.0 TT V6.

  • V-Band Coupler from Turbo to Down Pipe. This will make replacing the factory catalytic converter with a free flowing down pipe easy and leak free. V-Bands are one of the most effective ways to fasten exhaust parts together (especially areas of higher pressure and heat). Because the V-Band Coupler applies an inward radial force compressing the flange together, you have less chance for an exhaust leak with less effort of tightening.
  • No VVEL! Not that VVEL was inherently bad, but it was a major culprit in the heat issues experienced in the outgoing VQ engine. Nissan/Infiniti has switched to a new Valve Timing System (controlled by an electric motor accord to them).
  • Standard Turbos. With no mention of twin scroll technology, this could mean for more options when it comes to possibly upgrading the turbos.
  • Exhaust System. It looks like the cat-back section of the exhaust has not changed with the new motor. This would mean the current cat-back and axle-back options would still work. Do note, most cat-backs were not designed with forced induction in mind. STILLEN does have an advantage here because we designed our Cat-Backs to work with forced induction. This mainly applies for the Q50 as it will be the first Nissan/Infiniti to get the new Turbo motor.
  • Oil Filter. The location of the oil filter look very convenient for installing an oil cooler. While we don’t anticipate the VR 3.0 TT to have the same heat issues that the VQ’s had, it is always beneficial to keep those oil temps in check.


There will be some challenges, hurdles, and limitations. From what we have seen in diagrams and specification here are going to be some of the limiting factors of this motor and some possible solutions (these are just possibilities that cannot be confirmed till we have this motor to actually look at in person).

  • Integrated Exhaust Manifolds. While this does help reduce the size of the motor and provide some nifty emissions benefits, it does limit the capabilities of what we can do aftermarket.
  • Optical Turbo Speed Sensor (only available on 400hp variant). While this is an amazing tool for tuning and being able to run the turbo at peak efficiency, it does not come on the 300hp variant of the motor. This might make tuning less accurate. We won’t know till we take a closer look, but there is a huge advantage to being able to tune based on both boost and turbine speed.
  • Water-Cooled Intercooler System. While Air to Water intercoolers are great, they do provide some potential stumbling blocks on this motor. If you look at the location, it will be difficult to upgrade them. While upgrading the heat exchanger in front and possible the pump is fairly easy, big power would most likely require a Air to Air setup and the turbos are positioned to feed directly into the factory coolers. Just means more piping than what we’d like to add if that becomes the case.
  • Intake Manifold. You can see there might be some major restrictions, bottle necks, and harsh turns on the factory unit. This may be simple to remedy, but depending on how the manifold is designed and what the reset of the manifold and lower plenum look like it could be difficult and expensive. At first glance you can see some areas that look restrictive, but from other angles you can see how it is just a design feature, and not a bottle neck.
  • Air Boxes. Because we know the core support design has not changed in the new Q50, new air intake systems will require some major testing to see if we can place the filter outside of the engine bay. This is more crucial on the Turbo motor than the old VQ37 because turbo motors generate much more heat in the engine bay. When the new Q60 and Z are released we can see if the design is different than the Q50.


NASHVILLE (Dec. 15, 2015) – Infiniti’s new compact, lightweight 3.0-liter V6 twin-turbo engine is the most advanced V6 engine that the brand has ever offered, striking an ideal balance between drivability, efficiency, and performance. The 3.0-liter V6 twin-turbo is an all-new engine from the new and exclusive VR-series powertrain family, born out of the brand’s longstanding heritage of V6 powertrain production. The new engine has been engineered to empower the driver and offer increased power and torque and higher levels of efficiency than any comparable predecessors from the company.

While all of this is based off of the information provided, and images available, we cannot say for sure what the potential is until we have one to do testing with. Never the less, we are very excited for the newest V6 from Nissan/Infiniti and can’t wait to start tuning them.

STILLEN Attends the First Annual NissFest!!!

STILLEN is deep rooted in the Nissan/Infiniti Community. So obviously when we heard there was going to be a new annual event for Nissan & Infiniti, we had to get involved.

The 1st Annual NissFest event was held at Auto Club Speedway in Fontana. With this being the first show and also taking place a little later in the year we were still very happy with the turn out. It was great seeing a lot of the local Nissan/Infiniti Enthusiasts happy to come out, show off their cars, visit vendors, and also just admire what others had done to their cars as well. We are very much looking forward to next year and hope to see even more people attend!

It was also great to see so many cars featuring STILLEN Parts. Here are some of our favorites from the show!

We are pleased to announce the release of the STILLEN Infiniti Q50 Sway Bar Set.

Sway Bars are easily the biggest performance upgrade you can make to your car’s suspension. Though not as popular as lowering a vehicle because there is no aesthetic change, it is a much more noticeable and dynamic modification. Modern vehicles (especially luxury cars) are designed with comfort in mind first, and then handling is more of an afterthought with most consideration given to safety. Because of this, we often find ourselves with a car that has great potential, but has a tendency to understeer and wallow through turns.


The STILLEN Q50 Sway Bars solve this issue by strengthening the link between both sides of the suspension. This results in less body roll, a stronger contact patch, and better balance in and out of turns. The Sway Bars are also adjustable allowing you to tune your suspension to favor Understeer or Oversteer. No matter what how you drive your Q50, the STILLEN Sway Bars are comfortable enough for everyday driving, while providing the performance you want for canyon carving and/or the occasional track day.


STILLEN Q50 Sway Bars (304396) Feature:

  • Front Sway Bar
  • Rear Sway Bar
  • 3 or 5 way adjustable
  • Red Powder Coat Finish
  • Hollow Tube Construction for weight savings
  • Fits RWD Q50, Q50S, Q50 Hybrid, and Q50S Hybrid
  • Made in America

AWD Setup is currently in development and should be ready in the near future.

Even straight from the factory, the Infinit Q50 comes with a lot of bells and whistles, but we always like to see cars with a few more – especially when they have STILLEN aftermarket parts installed on them! Our friends at Crest Infiniti have worked their magic on another one of their showroom Q50s and have truly taken the car to the next level.
