Although every bolt-on GTX 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 GTX 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 GTX3576R is a great match for the 2.5L that still has great spoolup, especially if you're looking for boost threshold that is just a little later than stock but still want enough airflow for 650+ HP. The GTX3576R makes boost about 200 to 300 rpms later than the GTX3076R but keeps pumping where the GTX3076R starts to run out after 600HP.A lot of the boost is available even at part to medium throttle. Dual ball bearings means 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 GTX3576R 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 650 HP turbos are still "spooling up". Dual Ball-Bearing Turbocharger for the best spool time - You can still hear the wheel spinning after you shut off the motor.
