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