Looking to turn your Infiniti G37 into a boosted street or track weapon? Not sure where to start? We’ve got you covered!

When the Infiniti G37 was launched, Nissan’s premium brand undoubtedly aimed at the higher end of the market. With a high price bracket and comfort and style in mind, the possibility of modifying one was a pipe dream for your everyday car enthusiasts.

Now, with a huge slash taken off the retail price over the years, the G37 has stood the test of time and can now be owned at an extremely affordable price point, offering an incredible everyday car once modified.

However, what if you’re looking to get that little more out of the V6 engine on the track, or even the road? Superchargers are known as the perfect way to extract a substantial amount of missing power from your engine.

Tuning houses from across the world have been handed the opportunity to squeeze the missing ponies out of the VQ37VHR and they’ve done an incredibly good job in the process, we’re now going to show you the kits on offer to unleash the potential!

STILLEN to the rescue

Stillen initially had competition from GTM/Gamma Motorsport in the G37 supercharging scene, however with the latter failing to stay in business, it’s safe to say that former 300ZX racing legend Steve Millen’s ‘STILLEN’ option is by far the best choice available on the market.

For those of you who don’t know already, Steve Millen is also the uncle of Formula Drift Champion Rhys Millen.

Take a quick look at Steve Millen’s legendary 300ZX which handed him the most all-time wins in IMSA GTS history with 20 victories.

“Looking to extract more horsepower and torque from your G37, 370Z or Q50? How does around 380HP at the wheels grab you?”

Since we assume you’ve already done the necessary upgrades to get the most out of your G37, such as a free-flowing exhaust, air intake, or maybe a set of coilovers? After power? A supercharger could well be the perfect compliment to end your quest for additional power!

With their G37 kit opting for the Vortech V3 centrifugal supercharger which is capable of reaching over 500 horsepower (with supporting mods), the 50-state emissions compliant intercooled setup is available for purchase at Enjuku Racing for just $7,495.

Deciding your options

Since the above option comes with a cable enabling you to put the preset tuning method onto your ECU, you also have the option of a non-cable version of their polished-look supercharger kit if you want to get tuning done locally which is available for $6,795, here.

Power on tap

One of the best things about the kit is that the setup to gift your G37 with boosted goodness is straightforward with their off-the-shelf parts and a typical install time of just 12 hours.

“Scenery gets blurry-in-a-hurry as the centrifugal Vortech blower spins up to hyperspeed with a telltale hiss.”

If you’re on a quest for big power, the Vortech V3 is more than capable of reaching over 500 horsepower with 9psi of intercooled boost pressure whilst delivering compressor efficiencies above 75%.

The V3 also benefits from a self-contained oiling system which is completely independent from the engine’s lubrication system.

The beast in action

We’ve searched the web to bring you some of the best offerings to decide whether supercharging is the ideal route for you.

Varying from dyno to full car reviews, we have no doubt that these videos will help you make your mind up!

Now that you’ve enjoyed the videos you’re probably more tempted than ever to supercharge your G37. Here’s some more helpful information from the manufacturer regarding their off-the-shelf kit from Enjuku Racing:

“Looking to extract more horsepower and torque from your G37, 370Z or Q50? How does around 380HP at the wheels grab you?”

“Add a dose of torque, better-than-stock heat management and airflow, 50 state emissions compliance and near stock fuel economy at low RPM. Now you’ve got the formula for superchargers done the STILLEN way.”

“We’re talking driveable horsepower too, suitable for daily drivers, canyon carvers and track days.”

“What does ‘driveable’ mean? Take an unsuspecting passenger for a low RPM cruise around town in your STILLEN supercharged Infiniti G37, Nissan 370Z or Infiniti Q50. Keep a light touch on the gas pedal and they might be fooled into thinking there’s a bone stock motor under the hood.”

“They won’t suspect a thing….until you hit the town limit sign and crack the throttle wide open.”

“Scenery gets blurry-in-a-hurry as the centrifugal Vortech blower spins up to hyperspeed with a telltale hiss. The STILLEN designed and built intake manifold sucks in cubic yards of cool air. The remapped ECU fuel management module jacks the boosted fuel pump to inject the precise amount of high octane cocktail into the maelstrom.”

“Your right foot is orchestrating a symphony of controlled violence that delivers a linear, bottomless powerband. If you can peel your head off the headrest to sneak a glance at your passenger you’ll see instant enlightenment and heavy G’s at work.”

The design

“STILLEN designed a new cast aluminium intake manifold specifically for this system, featuring longer runners and a large plenum for the engine to draw air. An integrated air-to-water intercooler system dramatically cools the air charge from the Vortech V-3 Supercharger unit.”

“The V-3 features a self-contained oiling system and quiet V-belt design, with plenty of additional boost capability for those wanting even more power down the road.”

“STILLEN took extreme care in designing this system, ensuring that all additional coolers (oil, transmission, power steering, etc) would work with the intercooler system, as the Nissan VQ37 engine is prone to high oil temperatures unless properly cooled.”

“At all levels of development the system was tested, both for street drivability and reliability under normal traffic and freeway conditions. Stillen drivers flogged the test car at El Toro Air Base, with repeated 140+ mph runs and hard driving on tight courses with excessive revving and redlining. Testing included extensive monitoring of all pertinent air and fluid temperatures.”

“They won’t suspect a thing… Until you hit the town limit sign and crack the throttle wide open.”

Cable or non-cable?

“To tune these supercharger systems STILLEN works with UPRev software. This software requires a license and a cable to load the tune into the vehicle’s ECU. The With Cable option is designed for customers who may not live near an UPrev certified tuner or for a dealership who is completing the installation. This is also a great solution for the DIY guy looking to install the kit in his garage.”

“The “without cable” option is supplied with all of the hardware and the tune. This solution is good for someone who is working with an UPrev pro tuner that already has the licenses and loading cable in their facility. This way you don’t need to pay extra for something you might already have access to. Either way, the tune is the same.”

Ease of installation

“One of the hallmarks of a STILLEN supercharger is ease of installation. Much of the assembly of the kit is completed here at STILLEN before we pack and ship your supercharger. The main supercharger unit is pre-assembled to the laser-cut billet aluminium mounting brackets. Installation is very straight forward, including detailed step-by-step instructions. Typical install time for a competent shop is 12 hours.”
