GT3076R: ATP describes the GT3076R as the right tool to do 500+ HP job. This turbo can support 500+ horsepower on the 2.5L. While the 3076R has a little more lag than the smaller units (it makes boost about 400RPMs later than the GT3071R), but it makes more top-end power. 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 GT3076R is the modern GT30R and not the sporatically named -10, -11, -12, -13, -14 series from the old days misused and abused as GT30's. If you're looking for a 500hp turbo for your WRX or STi that is streetable, and has a decent powerband, look no further.
The GT3076R has a 60mm turbine wheel with an 84 trim and 76.2mm, 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
