GReddy T518Z Tuner BRZ Turbo Kit

Our comment: There’s no question that the Japanese tuning legends know this market well and it definitely shows with their turbo kit. The setup combines perfect fitment alongside with the stunning quality that we’ve come to expect from GReddy over the years.

This intercooled racing turbo system has been quoted as delivering around 90hp by GReddy themselves, but even when ran at the stock 7psi by owners it has often dyno’d well above this.

Manufacturer description:GReddy Performance Products is excited to announce the release of the highly anticipated T518Z Tuner Turbo Kit for the 2013- Scion FR-S and Subaru BRZ. With extensive testing both in Japan and the USA, this turbo kit was designed to enhance the overall performance for daily drivers and weekend racers. An ideal turbo sizing maintains the vehicles balanced driver feel, by maintaining good low-end response with the factory engine components. But the most noticeable improvements can be noticed on the factory power-band’s dip in mid-range torque and at high RPM top-end power.”

“GReddy dyno test showed a +93.5whp / +68.7ft-lbs increase at 7psi on a stock 2013 Scion FR-S with factory injectors and fuel pump, just adding a *GReddy-tuned EcuTek ecu, and a *GReddy Evo3 70mm exhaust, – (* Not Included) But even more importantly, the mid-range torque from 3150-4750 RPMs are significantly improved over the stock torque curve.”

Our comment: WORKS have spent two years engineering this unique kit for the market and it’s undoubtedly going to leave some owners extremely pleased. With a 50-state smog legal cert, you won’t need to worry about getting pulled if you’re planning to drive this kit on the street in the US.

Owners have had their WORKS Stage 1 kit dyno tested with gains of around 70hp at stock 7psi.

Whilst this kit features fantastic quality, results and ease of fitting, it lacks an intercooler which may put some users off. If this is the case, but the CARB compliance is appealing, their Stage 2 kit below may well be for you.

Manufacturer description:After almost two years of engineering development and testing, WORKS is proud to introduce their Stage 1 “Simple” Turbo Kit for the FR-S/BRZ.”

“The sophistication and elegance of our kit is found in its simplicity. Through the use of custom thermal coated up and down pipes, custom intake piping including a finned aluminum air-to-air heat exchanger, OEM style diverter valve, centered around a genuine Garrett GT28 journal bearing turbo, you will reap the benefits of efficient turbo-charged power while still retaining your OEM air box, OEM exhaust manifold headers and OEM secondary catalytic converter (front pipe). Containing all necessary equipment for added oil and coolant routing, as well as heat shielding and specialty hardware, it is truly a bolt-on and OE quality upgrade, requiring no cutting, fabrication, or internal engine modification.”


WORKS Stage 2 CARB Compliant BRZ Turbo Kit

Our comment: With WORK offering the CARB compliant Stage 1 kit above, we couldn’t ignore the lack of intercooler which their Stage 2 kit offers. This setup is a further improved option with an air-to-liquid intercooler and higher boost threshold.

Now running 12psi of boost, this kit can provide gains of over 90hp, which is a 55% increase over stock. These gains combined with the CARB compliance may be the perfect package for your needs!

Manufacturer description:The WORKS Stage 2 Turbo Kit for the FR-S/BRZ takes the performance of our Stage 1 Turbo Kit to the next level with the addition of an air-to-liquid intercooler and a higher boost threshold. Stage 2 is for those who want more power than what our Stage 1 Kit provides, but still wish to retain its simple and minimally-invasive configuration.”

This kit utilizes a genuine Garrett GT28 journal bearing turbocharger to provide efficient, turbocharged power while retaining the OEM airbox, exhaust manifold, and secondary catalytic converter. Our team of engineers spent hundreds of hours in design, development, tuning, and testing to produce a simple and reliable turbo setup to enhance the driving experience of the your vehicle. This is the easiest-to-install, most cost-effective, and least-intrusive air-to-liquid intercooled turbo system available for the FR-S/BRZ.”

  • Manufacturer: Full Blown
  • Fitment: Subaru BRZ, Scion FR-S
  • Turbo configuration: Single turbo
  • Price: $3,989.00
  • Drifted rating:xxxx

Our comment: Full Blown have come up with this well-priced offering of their Stage 1 premium turbo kit. Despite being the cheapest on our list, it is rated up to an impressive 440hp provided you have the required supporting mods.

This is an extremely popular offering among BRZ and FR-S owners and with lots of great kit options available from quick spooling to big power, it’s easy to see why it’s the perfect choice for many owners.

Manufacturer description:We realized that our Stage 1 premium turbo kit did not meet everyone’s budget so we decided to put together a more affordable kit for the guys who are looking at turboing their BRZ. The main difference from this kit compared to our Premium kit is that we were able to CNC bend most of the piping, and casted the intercooler tanks to reduce cost. ”

“We also ditched the the Tial housings for the standard T3 flange (this will allow you to run Precision turbo or other makes in the future). We switched to a 39mm wastegate and went with a standard T3 50 Trim, T3 57 Trim, or you can upgrade to the GTX (Please see option).
