ATP Turbo GT3582R Bolt-on Turbocharger Kit 2002-2015 Subaru WRX STi EJ20/EJ25 (2.0L/2.5L) - Stock Location; External Wastegate - 600 hp

It's a lot of work, but ATP has done it!

This ATP Turbocharger Kit features the Garrett GT Ball Bearing GT35R (aka GT3582R aka GT35/40R). The GT35R is the ultimate 600+ HP capable dual ball bearing turbo and is now available in a drop-in package for the Subaru WRX/STI! The easy to implement turbo assembly that takes no more than 1-2 hours to install in place of the stock journal bearing VFXX unit is made possible by a high flowing GT inspired ATP exhaust housing and a series of custom engineered components built to suit the installation.

Each GT drop-in turbo package consists of a Garrett factory assembled and high speed balanced dual ball bearing CHRA which is then assembled into a set of CNC machine ported housings that have been optimized in every aspect for maximum flow and efficiency.

All accompanying oil and coolant supply components included in each kit have been designed to properly and seamlessly bridge the Garrett GT turbo to the EJ engine so that the fit is as OE as possible.

Just bolt the turbo on, add fueling and a good tune and prepare for a blast of acceleration. Garrett GT turbos offer more then just "peak HP" numbers. These GT turbos off more torque area under the curve and more "accessible" power then any other turbos series out there.

We do recommend that you compliment your GT bolt-on turbo with a nice high flowing bellmouth downpipe and a high flowing inlet pipe to effortless channel air in and out of the turbo. Although every bolt-on GT turbo ships with a 3" inlet, we do provide a "stepdown" sleeve just in case you're forced to use the stock 2.25" inlet hose. However, as a rule of thumb, turbos, especially higher flowing units love as much inlet flow as possible. This promotes both quicker spoolup and better ultimate HP, with less boost pressure at the manifold. The 3" downpipe and bigger inlet is critical for reaching peak efficiency on the GT turbo. Please also be aware that some downpipes such as the stock catted downpipe, has a "no-flow" door at the wastegate flapper area. This type of downpipe may not allow the wider swinging wastegate valve to open all the way, thus causing the possibility of a "boost-creep" condition or uncontrollable rise in boost.

The GT3582R is a great power maker on the 2.5L that still has great spoolup, especially if you're looking for best area under the curve possible, but still need a lot of power in the high revs. The GT3582R makes boost about 200 to 300 rpms later than the GT3076R but keeps pumping where the GT3076R starts to run out after 500HP. A lot of the boost is still available at part to medium throttle. Dual ball bearings means some boost is always there even if you are lugging the engine and 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 onse of each gear. The 2.0L driver should not rule out the use of the GT3582R if his HP target is in the same range. This competition grade turbo is still a big favorite for the HP range because it hits like a hammer while other 600HP turbos are still "spooling up". Just like the GT35R kit ATP-SUB-002 but with built in flange for Tial 44mm wastegate on the turbine housing. High flow, less exhaust backpressure, more precise boost control, even more power! Optional Tial 44mm wastegate and dump tube sold separately.
