In a hurry? Here is our FR-S Turbo Kit summary

So, you’re lucky enough to own one of the most well-refined sports-coupes of our generation and you just can’t help but crave more power for skids and burnouts? We’ve got you covered!

Created as the predecessor for the legendary AE86, Toyota decided it was time to once again bring the joy back to motoring with the GT86, which then took the US market by storm when rebranded as the Scion FR-S.

Although it was designed to be a light chassis with skinny tyres and enough power to kick the rear end out when you want to, some owners are understandably left wanting more.

As always, the temptation to lower the suspension, throw some wide, grippy tyres on and make it look even better than it left the factory is the firs thing on owners minds. However, with your new found grip and 2.0 N/A, you’ll probably realise that you now need more power to go with it.

This is where several tuning companies have come head-to-head to fight for the best aftermarket turbo kit available for your FR-S to give it that much needed boost!

With plenty of options available when it comes to supercharging or turbocharging your FR-S, it mainly comes down to personal preference to decide which method is best for you.

Check out our comprehensive turbocharger vs supercharger guide to see what is the right solution for your FRS.

We’ve written this guide to help you narrow down the difficult decisions when it comes to turbocharging your FR-S and find the perfect kit for your needs.

GReddy T518Z Tuner FR-S Turbo Kit

• Manufacturer: GReddy
• Fitment: Scion FR-S, Subaru BRZ
• Turbo configuration: Single turbo
• Value for money: 🔥🔥🔥🔥
• Purchase link: Discontinued

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.”

WORKS Stage 1 CARB Compliant FR-S Turbo Kit

• Manufacturer: WORKS
• Fitment: Scion FR-S, Subaru BRZ
• Turbo configuration: Single turbo
• Value for money: 🔥🔥🔥
• Purchase link: WORKS Stage 1 Turbo Kit

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 FR-S Turbo Kit

• Manufacturer: WORKS
• Fitment: Scion FR-S, Subaru BRZ
• Turbo configuration: Single turbo
• Value for money: 🔥🔥🔥🔥
• Purchase link: WORKS Stage 2 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.”

Full Blown FR-S Turbo Kit

• Manufacturer: Full Blown
• Fitment: Scion FR-S, Subaru BRZ
• Turbo configuration: Single turbo
• Value for money: 🔥🔥🔥🔥
• Purchase link: Full Blown FR-S Turbo Kit

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 FR-S and BRZ 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 FR-S. 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).“

HKS GTIII-RS FR-S Turbo Kit

• Manufacturer: HKS
• Fitment: Scion FR-S, Subaru BRZ
• Turbo configuration: Single turbo
• Value for money: 🔥🔥🔥🔥
• Purchase link: HKS GTIII-RS FR-S Turbo Kit

Our comment: The most recent kit to hit the market comes from JDM legends, HKS.

Refining what tuning houses have learned over the years from their mistakes with the various turbo kits, many owners believe this to be the best option available.

While some kits are focused on big-power numbers, HKS is keen to maintain their impressive reputation for reliability, with respectable power figures.

We’ve seen owners run anything from 250 hp through to more than 400 hp with this kit, but uprated internals will need to become a consideration if you’re looking for significant power.

HKS believes that 450 ps (440 hp) is reliably achievable with the correct tuning, and several enthusiasts are keen to prove it has further untapped potential.

Thanks to the engine providing sufficient torque, the turbo lag from this kit is subtle rather than uncontrollable, making for a great street setup that’s still more than capable at the track.

Overall, this kit is an excellent all-arounder, bringing the typical quality that you’d expect from HKS.

Manufacturer description: “The HKS Turbo Kit for the 2017+ Toyota 86, 2013+ Subaru BRZ, & 2013-2016 Scion FR-S was designed and engineered to add a significant power bump to the ZN6/ZC6 chassis. It is a 100% bolt-on kit shown to provide ~350 hp with a stock FA20. The kit can be used on it’s own, or paired with other upgrades for more power (built motor tested to ~450 hp).“

“The kit includes all the necessary hard parts for installation. You will need to purchase engine management separately (piggy back or stand-alone), larger injectors are necessary (440cc or higher recommended), and upgrade the (for 3 BAR boost) pressure sensor.“

Our winner

Our winner is the WORKS Stage 2 FR-S Turbo Kit

To pick our winner from this choice of FR-S turbo kits we looked at a number of criteria; ease of installation, power levels, upgrade potential and price point.

Based on these criteria we have chosen the WORKS Stage 2 FR-S Turbo Kit to be our winner.

Updated 19th November, 2020: The GReddy T518Z was our deserved winner, however, recently GReddy has unfortunately decided to discontinue this turbo kit. Since this kit is no longer on the market, we have decided to award the win to the very solid WORKS Stage 2 turbo kit.

WORKS Stage 2 FR-S Turbo Kit

With the high quality of components, popularity and CARB compliance, it’s the WORKS Stage 2 turbo kit that takes the win in our review. This kit also gives you the benefit of not having to worry about having undeclared mods under the hood.

All four options undoubtedly have their positives, the Full Blown kit is immensely popular, the GReddy kit is an excellent choice but is sadly no longer available, although if you can find a used kit that might be worth considering.

If none of these kits are what you’re after, why not consider an engine swap? The guys at SR Tuned on Facebook, Instagram, and YouTube have something a little different to offer.

This small company has developed a bolt-on plug-and-play kit for the 1st generation GT86 platform with a 2AZ-FE engine swap, with several owners currently running their setup.

The guys at SR Tuning have kept the weight at 2,822lbs, with factory front-to-rear balance and a near 50/50 balance left to right.

With a base power output of 314 hp and torque at the wheels on stock internals, this kit presents another fantastic opportunity for those considering a swap on their GT86/BRZ/FR-S.
