ATP GTX3582R Stock Location Turbo w/ TiAL MV-R Wastegate Package - Red EWG and dump tube
Just like the GTX3582R kit ATP-SUB-022 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!
The Garrett GTX Ball Bearing GTX35R (aka GTX3582R aka GTX35/40R), the ultimate 600+ HP capable dual ball bearing turbo, 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 GTX inspired ATP exhaust housing and a series of custom engineered components built to suit the installation.
Each GTX 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 GTX 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 GTX turbos offer more than just "peak HP" numbers. These GTX turbos off more torque area under the curve and more "accessible" power than any other turbos series out there.
We do recommend that you compliment your GTX 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 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.
The GTX3582R 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 GTX3582R makes boost about 200 to 300 rpms later than the GTX3076R but keeps pumping where the GTX3076R 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 onset of each gear. The 2.0L driver should not rule out the use of the GTX3582R 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".
