ATP GT3082R Bolt-On Stock Location Kit Turbocharger Externally Gated Subaru WRX 2002-2007 / STI 2004-2017
The Garrett GT Ball Bearing GT3082R, 500+ 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 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.

Just like the GT3082R kit ATP-SUB-010 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 shown are sold separately ****.
