With months of testing, developing, and designing, Agency Power has completed the best GT35R complete turbo kit for your Subaru WRX or STI vehicle. This turbo kit is a bolt on high horsepower solution to your 2.0L or 2.5L car. The AP big GT35R turbo kit is designed to maximize performance for street, drag, or the ultimate road racing needs.
The kit includes all T304 stainless steel piping that is TIG welded and thick flanges. Piping includes a new 3" downpipe that will fit to your aftermarket or factory exhaust, a new uppipe to work with the factory style headers, a wastegate dump pipe, and a new intake pipe with MAF mount for perfect readings. The Garrett GT35R turbo is a complete ball bearing turbine that has a .63a/r for fast spool up and includes an 84 trim wheel. The turbo is both oil and water cooled. Agency Power supplies the necessary steel braided Teflon lines and Rubber hoses need to fit the factory connections. We also include a Tial 38mm wastegate to control pressure for maximum boost needs. The intake functions with a reusable K&N cone air filter. A stamped bracket is included to keep the intake pipe firm in place. Silicone couplers are available in red to connect the necessary piping. The kit includes an intercooler adapter pipe which connects from the compressor of the turbo to the intercooler piping. We have tested the kit with the APS, TurboXS, Perrin, and OEM top and front mount intercoolers. Lastly all stainless steel hardware is included to bolt the turbo kit together keeping it hassle for free for the life of it on the car.
The Agency Power GT35R turbo kit is designed to make over 500 wheel horsepower on race gas and over 400 wheel horsepower on pump gas as tested on the STI. The WRX will produce less horsepower on the stock motor. All numbers vary depending on car modifications, tuning, and environment. This turbo is custom designed to spool up at around 4000rpm's to give the best horsepower response throughout the powerband. The turbo is capable or running 30psi and greater of boost, however we recommend many modifications to ensure the safety of the motor. Contact Southeast Performance for other Turbo Kit applications.
