Fast Intentions G37 Turbo Kit

fast intentions g37 turbo kit

Our comment: Fast Intentions have developed a completely new design as they push the limits with their Twin Turbo kit. Not only have they managed to conquer the 1000 wheel horsepower barrier with their insane Stage 3 G37 twin turbocharger kit on the VQ37VHR, but their setups have also won over many owners with their high-quality, reliable turbo options.

The increasingly popular Stage 1 kit features twin Garrett GT2860RS turbochargers capable of an impressive 700+WHP with additional engine modifications. If you’re hunting for even more power, their Stage 2 kit, run by Chris Forsberg In Formula Drift, is rated for in excess of 800WHP, and Stage 3 at a proven 1,000WHP.

***WARNING*** Although Fast Intentions do not list their G37 kit on the website,  they previously make kits for the car, so if you contact them, we have no doubt they’ll be happy to help.

Manufacturer description:In 2012 when we took on this project, our goals were clear cut. 1) Address and fix the flaws that the current TT systems on the market had. 2) Create the most reliable and efficient TT system. 3) Raise the power and torque threshold of the VQ37VHR engine.

“We are proud to say that we’ve far exceeded our expectations. Throughout the design process of our TT system, we have adapted and utilized 3D C.A.D. software “Solidworks” to create specific oil and cooling components. This entire TT system is manufactured in the U.S.A.

GReddy G37 Turbo Kit

  • Manufacturer: GReddy
  • Fitment: Nissan 370Z, Z34
  • Turbo configuration: Twin turbo
  • Value for money: 🔥🔥🔥
  • Purchase link: Buy GReddy VQ37VHR Tuner Kit

Our comment: Undoubtedly, GReddy is one of the most well-known names in the Japanese tuning scene. This time Greddy has shown its hand with an impressive kit capable of pushing out over 850 HP with additional engine modifications.

This tuner kit features twin TD06SH-20G twin turbos and a great package to get you started. This is a great quality kit, as we’ve always come to expect from GReddy products, and many owners have successfully had impressive power figures and long term reliability from it.

GReddy appears to have discontinued its turbo kit from production at the time of review. However, it’s still available today for purchase from other retailers.

***WARNING*** Alongside being discontinued, GReddy never made a specific G37 kit. For this reason, we recommend talking with a local specialist regarding modification to make this kit bolt onto your G37.

Manufacturer description:Introducing the latest addition to Greddy’s line of Tuner Turbo Kits, the VQ37VHR twin-turbo system boasts an impressive 175 horsepower increase at a mere 6.4psi of boost.

“Greddy provides the hardware to make the power, but the tuning components are left up to you to give you the best options. With additional engine work and tuning, this tuner kit has the potential of making 850 plus horsepower just as Greddy was able to achieve on their TT 350Z HR.

  • Manufacturer: AAM

  • Turbo configuration: Twin turbo
  • Value for money: 🔥🔥🔥🔥🔥
  • Purchase link: Buy your AAM G37 Turbo Kit

Our comment:  U.S.-based AAM introduced their OEM style fitment turbocharger system in 2014 using new twin-turbos from their partnership with BorgWarner. This quickly became one of the most sought-after offerings and, to this day, quite possibly the most commonly found kit amongst G37 owners.

Combining an impressive power output of up to 500HP per turbo and an OEM-style fitment combined with reliability and impressive build quality, it’s easy to see why the kit has maintained its popularity and praise.

AAM can give themselves a pat on the back for coming out with this fantastic G37-specific kit, the highest-regarded option on the market.

STS G37 Turbo Kit

sts g37 turbo kit

  • Manufacturer: STS
  • Fitment: Nissan 370Z, Z34
  • Turbo configuration: Rear mounted single turbo
  • Value for money: 🔥🔥🔥
  • Purchase link: Discontinued

Our comment: STS is well-known in the tuning scene for its work on muscle cars. This time, they brought this unique rear-mounted single turbo offering to the market for those looking for something different.

Some owners mention that the front-mount intercooler is a little on the small side, and if you’re looking for a larger one, it comes at an additional price. It appears to be an extremely easy kit to fit, even with basic knowledge.

However, after hearing about potential issues with piping such as rust problems with methanol injection. We highly recommend you speak with the manufacturer regarding to see if they can offer a solution before purchasing.

***WARNING*** This kit is specifically made for the 370Z, however there are many G37’s currently running the STS kit, so we also highly recommend discussing with them if you’re after a rear-mount turbo setup.

Manufacturer description:At only 5.5psi we are getting over 400 rwhp. That’s 125 more than stock! With methanol injection you can safely make over 500rwhp! We also offer numerous turbo upgrades that will support up to 950chp!

“The average install time for this kit is between 8 & 12 hours depending on options. The ONLY modifications to the vehicle is drilling a small hole for a clamp and cutting a small ear off the plastic radiator support to allow an intake pipe to be installed. If you can install a cat back exhaust and a cold air intake, then you can install this kit by following the detailed full-color instruction manual.

SFR G37 Turbo Kit

sfr g37 turbo kit

  • Manufacturer: SFR
  • Fitment: Infiniti G37
  • Turbo configuration: Twin turbo
  • Value for money: 🔥🔥🔥🔥
  • Purchase link: Buy your SFR G37 Turbo Kit

Our comment: Another company that created a unique offering for the G37 is SFR. They gained a huge following in the 350Z world with their DE offerings, however, they’ve seemingly gained little traction with their G37 turbocharger systems. As expected from SFR, it seems to be another fantastic choice but with little popularity.

If you feel that going with a reputable company with good customer support suits you, we recommend speaking with SFR or TurboKits directly to get more details on this kit.

Manufacturer description:This system fits automatics and manual transmissions. The front aluminum crash bar can be retained.

“Automatic car is capable of running 450-500WHP on the stock engine. Six Speed car is capable of 550-600WHP on 10psi of boost.

SOHO Motorsports G37 Turbo Kit

soho single turbo g37 turbo kit

Our comment: Entering the game with their top mount single turbo kit, this well-refined offering from SOHO Motorsports has become a popular choice within the Z community.

After the fantastic feedback from customers regarding their 350Z turbo kits, they’ve provided their knowledge and expertise to produce some of the best Z kits on the market.

Utilizing a Garrett G35-900 setup in reverse rotation, the kit is perfected for 6-speed manual, 5-speed auto, and 7-speed auto G37s.

Curious about what a SOHO Motorsport turbo kit can do to your G37? Then, check out the clip below!

The Stage 1 kit is suitable for around 500 WHP, with 600 WHP achievable from the Stage 2 kit on pump gas, with figures nearer 650 WHP on E85 with 75% ethanol content.

One of the best things about the SOHO kit is the ease of installation, thanks to the reverse rotation single-turbo setup.
This setup utilizes the space in the already-cramped VQ bay without the hot pipe interfering with the power potential.

Manufacturer description:With the success that we have had with our single turbo kit for the VQ35DE, it was only a matter of time before we developed a single turbo kit for the VHR.”

We are proud to announce our newest single turbo kit for the VHR, which is the first reverse rotation top mount kit for this platform. The reverse rotation has allowed us to route the cold side and hot side piping in a manner that is favorable to the limited space in the VHR engine bay.

Our winner

Our winner is the AAM Turbo Kit.

To pick our winner from this choice of G37 turbo kits, we looked at several criteria; direct fitment, ease of installation, power levels, upgrade potential and price point.

Based on these, we chose the AAM Turbo Kit as our winner.

AAM G37 Turbo Kit

AAM has come out with this unique offering specifically for the G37. However, Fast Intentions won our 370Z guide and are still a fantastic offering. The lack of an off-the-shelf kit handed AAM the win this time.

With a fantastic kit and impressive gains, it’s easy to see why so many G-series owners opt for running the AAM turbo kits, which have also boasted impressive reliability over time.

We highly recommend that further research is done based on our guide. There are often additional parts, tunes, or upgrades for a base-level turbo that may be either vital or purely suit your preferences.
