ATP Bolt-On Externally Gated GT35R Turbocharger Subaru WRX 2002-2007 / STI 2004-2017


ATP 02-07 WRX & STi Stock Location Garrett GT3582R External Wastegate Turbo (can never be used w/ in


GT3582R: If you are looking for big power and fast spool – this is the one. This turbo can support 600+ horsepower on the 2.5L. (approxamitly 450whp on a 2.5L) Stepping up to this turbo puts you in a class above the rest. You will have slightly slower spool than the GT3076, but massive power up top. We do not recommend this turbo for 2.0L cars, unless they are full-race, built-block applications with head work. ATP’s WRX & STi GT3582R is the modern GT35R and not the sporatically named -10, -11, -12, -13, -14 series from the old days misused and abused as GT35’s. This is a true stock location bolt on turbo. The GT3582R has a 68mm turbine wheel with an 84 trim and 82mm, 56 trim compressor wheel. ATP has taken their revolutionary bolt on Subaru turbochargers to the next level by offering a direct fitment external wastegate. The exhaust housing is cast with a flange designed for a Tial 44mm wastegate, while the internal wastagate is eliminated permanently. This setup allows you perfect boost control, and will prevent any boost spiking issues commonly associated with a smaller internal wastegate.

When ordering specify year of vehicle and wrx or sti so we can send the right install kit.

Wastegate not included. Sold separately.
