Features
- This bolt on turbo kit for 86/BRZ is compatible with stock engines and focuses on low to mid speed for track
- The turbocharger is latest available exclusively for the 86/BRZ, combining the GT4525 and GT4135 CHRAs with specially designed turbo and compressor housings.
- The layout and specifications of the Catalytic Converter are made for the late-model engine, and a newly designed heat shield obtains a certificate of emission test results.
- You can enjoy 177kw (241ps) with GT4525 and 210kW (285ps) with GT4135 turbocharger with the stock engine.
- Torque output is kept within the range supported by the stock transmission, making transmission reinforcement unnecessary. (*1 *2)
- Power output is kept within the capability of the fuel system and the sensor, enabling turbocharger without the need for modifications. (*1 *3)
(*1) The “range of compatibility” of stock parts is only a guide and does not guarantee the strength of the parts.
(*2) Please note clutch should be reinforced.
(*3) Please install the exclusive data for Flash Editor at HKS Power Writer contract store.
The comparison of GT4525, GT4135, GTIII-RS
- GT4525 is set up for those who enjoy more power at low rpm during street driving. *The difference is more easily discernible in actual driving.
- GT4135 is designed for those who prefer high-revving power
The comparison of GT4525, GT4135, GTIII-RS
- To compare the boosting characteristics of each turbo, we compared the rpm rise time on the chassis dynamometer at the same boost pressure setting.
- When accelerating at full throttle from low rpm, the GT4525 with the lowest maximum power reaches 6000 rpm the fastest. The example shown in the left graph, there is a 1.5 second difference when comparing the time to reach 4000 rpm.
Based on the above, GT4525 provides the more output at the low rpm while corning or street driving, which makes feel driving faster.

Turbo Selection
GT4525 is designed for street driving and track racing. GT4135 has the characteristic for high output at high rpm and plenty of room for step-up.
If you are interested in high power with engine enhancement, please choose GTIII-RS.
* Because GT4525 is set to use up all of the turbo capacity, increasing boost pressure does not improve maximum output.
Those who consider stepping up to the next level, please choose GT4135 or GTIII-RS.
Turbo swap after kit installation
GT4525, GT4135, and GTIII-RS each has a different center housing, resulting in a different water piping configuration and oil piping thread size.
GT4525・GTIII-RS
* The piping has the same shape in appearance, but the bolt diameters and pitches are different, making it a separate part.
