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-005 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! Dual Ball-Bearing Turbocharger for the best spool time - You can still hear the wheel spinning after you shut off the motor. ATP Prioprietary Turbo Exhaust Housing with integrated external wastegate flange.
