Description
The WORKS Stage 2 Turbo Kit for the FR-S/BRZ/86 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 ball 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/86.
Notable Features:
Genuine Garrett GT28 water-cooled turbocharger mounted rearward to maintain chassis balance and handling
Air-to-liquid aluminum intercooler with front-mounted auxiliary radiator Internal and external ceramic coated up and downpipe
Short length intake piping and efficient intercooler core maximize boost response and minimize pressure loss/drop
Durable powder coated components with 4-ply silicone couplers and rolled edge hose clamps
Retains OEM airbox, PCV system, exhaust manifold, front pipe, and both catalytic converters
Compatible with aftermarket exhaust equipment that retains stock exhaust flange locations and bolt patterns
Oil pan removal and wiring harness extension not necessary for installation
~12 psi peak boost
Expect gains of ~90 hp, ~90 ft-lbs crank on 91 octane (R+M)/2 with a relatively stock vehicle
~55% power increase over stock using higher octane fuel can net greater power gains
Includes all metric hardware OEM/factory appearance
Please view our installation instructions for a deeper understanding of how minimally-invasive this system is:

We encourage the use of a high-flow air filter like the WORKS High-Flow Drop-In Air Filter with our kit. For track use, an oil cooler like the WORKS Oil Regulator/Cooler Kit ( discount when added as an option) and stiffer motor mounts are highly recommended. The significant increase in power should also be balanced with better braking performance like what our WORKS BP-1 Brake Package provides.
We offer 3 diverter valve/blow-off valve options:
The standard diverter valve used in the CARB kits fully recirculates.
The Forge Motorsport Splitter Valve can used to fully recirculate, fully vent (blow-off; will require plugging the inlet pipe) or a combination of recirculation/venting.
The GFB Respons T9025 Adjustable Bias Venting Diverter Valve/BOV can be adjusted to fully recirculate, fully vent (blow-off; will require plugging the inlet pipe) and every bias in between.
We offer 5 turbo options: Each turbo option has been specially configured so they are a direct fit with our turbo kit and come will all necessary hardware.
Turbocharger: Rated to:
Garret GT28 340 hp
Garret GT2871R 400 hp
Garret GTX2867R GEN-II 550 hp
Garret GTX2967R 560 hp
Garret GTX2976R 640 hp Note: Larger intercooler, downpipe and/or fuel pump & injectors are needed to take full advantage of the larger turbo options.
IMPORTANT NOTES:
Tuner Kits do not include an ECU calibration and require appropriate ECU tuning for proper operation.
Tuner Kits are not CARB compliant and can not be shipped to California addresses. See our CARB compliant 142.212C kit that includes an ECU calibration and is 50-state smog legal.
This kit is not compatible with right-hand drive vehicles at this time. Please see our installation instructions for a more comprehensive list of vehicle equipment prerequisites.

Q&A:
What are the advantages of a turbocharger vs. supercharger?
This is ofcourse a lengthy discussion, however a turbo has many benefits over a supercharger. Efficiency is the goal, and a turbocharger uses exhaust gasses already present to spin the turbine and create boost pressure. Meanwhile; a Supercharger is a belt driven unit; creating additional parasitic load on the engine and poor throttle response.
Additionally, the end user has much more control over boost pressure on a turbocharged vehicle: making more mid-range power/torque along with a consistent power band. Because the turbo isn't always "in boost" like a supercharger; this also means that there is less load while cruising around town or on the highway. Recently, we drove the WORKS Turbo BRZ down to southern California and averaged just over 30MPG highway on 91 octane fuel.
Is this turbo kit smog legal?
This kit is not 50-state smog legal. Our CARB compliant 142.212C carries CARB Executive Order D-748 and is 50-state smog legal.
Does the kit come with an ECU calibration?
An ECU calibration is not included with this kit and appropriate ECU tuning is required for proper operation. Please see our CARB compliant 142.212C kit that does include an ECU calibration.
How long does it take to install the kit?
Depending on mechanical aptitude, installation normally takes between 12 - 16 hours.
Does installing the kit require any cutting, fabrication or wire harness extensions?
Very minor sanding, drilling a hole and cutting a bracket is required. No factory wiring harness modification or extension is necessary! And no oil pan removal or modification necessary! Please see our installation instructions (link above) for a description of required modifications.
Do I need to remove the front bumper for installation?
Bumper removal is required for Stage 2. Please see our installation instructions (link above) for a description of the installation process.
How does this kit retain the factory exhaust manifold / headers?
Our kit only replaces the over pipe from the exhaust system, leaving all other exhaust components intact.
Will this kit work with aftermarket headers? How is turbocharger spool affected?
Our kit bolts up to aftermarket headers that maintain the stock header outlet flange location. Remember that the stock header contains a catalytic converter and two O2 sensors, so replacing the stock header with an aftermarket one will likely require software adjustments to our base calibration.
Spool characteristics are based on many factors that are unique to different header designs (volume, primary tube diameter, bend geometry, etc.) There are so many aftermarket BRZ/FR-S header options that it's not possible for us to make definitive statements about what aftermarket headers will do to the spool characteristics of our kit.
How do the battery and ECU housing handle the added heat from the turbocharger?
The exhaust piping included in our kit is ceramic coated which cuts down on radiant engine bay heat significantly. We include a battery heatshield in the kit, have monitored battery surface temperatures after track sessions, and have found them to be a non-issue when using the heatshield. The injector ECU showed no heat effects either. We provide thermal wrap in our kit to protect all wiring in the area of the turbo.
What power gains should I expect?
Each vehicle is different, but typically you should expect an increase of ~90 hp, ~90 ft-lbs at the crank on 91 octane (R+M)/2 gasoline - roughly a 55% gain. Using higher octane fuel can net greater power gains.
How is the drivability?
With proper engine calibration the kit has very smooth, factory-like drivability and keeps pulling to redline. We developed this kit to deliver a power level to match the capability of the stock chassis.
How much boost should I expect?
Stage 2 has a peak boost level of ~12 psi.
Do I need to upgrade the fuel system?
The factory fuel system is adequate for 91 and higher octane (R+M)/2 gasoline.
Will the kit void my warranty?
In many cases the turbo kit could affect your dealer warranty for the motor which is no surprise. However it should not affect the warranty of other components due to the Magnuson-Moss Warranty Act. Consult your local dealer for specific questions.
Is there a warranty from WORKS?
There is a 12k mile, 12 month warranty against defects in parts.
