08-10 Subaru STI ATP Bolt-On GT3582R Overview ATP's range of bolt-on Garret turbos are designed to provide the performance of a dual ball-bearing turbocharger with the convenience of a stock-location turbo. The ATP STI turbos easily install in place of the stock journal bearing turbo, due to the high-flowing GT-inspired ATP STI exhaust housing and a series of custom engineered components built to suit the installation. Every ATP STI GT drop-in turbo 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 and designed to attach to the STI uppipe. The turbo includes all the necessary oil & coolant supply hardware to seamlessly attach the turbo to your STI. ATP's focus with these turbos isn't peak power numbers; they're designed to make more torque under the curve and give you more accessible power. ATP recommends that you use a bellmouth downpipe with their bolt-on Garret STI turbos for optimal performance. Stock-type flat plate STI downpipes (HKS, DC Sports, etc.) and divorced wastegate downpipes (Perrin, Invidia Divorced) do not allow enough clearance for ATP's custom wide-swinging wastegate door. This can result in boost "creep," "spiking," and inaccurate boost control. The Turbo XS & Invidia Bellmouth downpipes would be good choices for use with this turbo. In addition, ATP recommends a higher flowing 3" turbo inlet, like the Perrin, Agency Power or APS. If you must use a stock-sized inlet, you will need to source a 2.4" to 3" reduction coupler, as the ATP turbos have a 3" inlet.We recommend using a matching-sized 3" inlet for minimal restriction, since GT turbos thrive with minimal inlet obstruction. ATP's tests have shown that these turbos, when used with the stock sized 2.4" inlet, produce significantly less power than when used with the 3" inlet. When coupled with a 3" downpipe, the 3" inlet promotes faster spool, and higher power numbers with less pressure at the manifold GT3582R If you are looking for big power and fast spool - this is the one. This turbo can support 600+ horsepower on the 2.5L. Stepping up to this turbo puts you in a class above the rest. You will have slightly slower spool than the GT3076, but massive power up top. ATP's STI GT3582R is the modern "GT35R" and not the incorrectly named -10, -11, -12, -13, -14 series from the old days misused and abused as "GT35's". This is a true stock location bolt on turbo. The GT3582R has a 68mm turbine wheel with an 84 trim and 82mm, 56 trim compressor wheel. FITMENT: Subaru STI 2008-2010
