ATP Bolt-On Externally Gated GT3071R Turbocharger Subaru WRX 2002-2007 / STI 2004-2019ATP's GT3071R is a great match for the Subaru WRX and STI's 2. 5L engine, especially if you're looking for boost threshold that is close to stock but want enough airflow for 450+ hp.

ATP's GT3071R is a great match for the Subaru WRX and STI's 2.5L engine, especially if you're looking for boost threshold that is close to stock but want enough airflow for 450+ hp. Almost all the boost is available all the time; even at part to medium throttle!. Boost recovery between gearshifts is awesome with full boost ready even before upshift is complete as the STI lurches forward with shear enthusiasm at the onset of each gear. If you have a built 2.0L and are shooting for 450+ hp, this turbo will work, although it will have significant lag. The modern generation of Garrett wheels, coupled with an awesome wheel ratio, allows even the smaller displacement EJ20 engine to provide adequate motivation to get the GT3071R going for a great powerband. The 3071R competition-grade turbo still offers the best response and spooltime out of any unit in this flow range. The GT3071R uses a 60mm 84tim turbine wheel and 71mm 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 and dump tube not included. Sold Separately.

Good luck
So far so good,fit perfectly but was a real bitch to replace on a 09 Crv. Tried from underneath but couldn’t get to the rear bolt, so I had to go from the top. Poor engineering on Hondas part.

Don't waste your money.
Instead of buying one from the local auto store, thought I'd save money and get this. Bad choice. Installed it and it didn't work. Took it to the auto shop to be tested and they said it didn't work. Cheap imitation of the the real thing.
