Here, you are looking at the ATP GTX3582R Externally Gated Turbocharger. Just like the GTX3076R kit ATP-SUB-021 but with built-in flange for Tial 44mm wastegate or similar-sized wastegates on the turbine housing. The result is higher flow with less back pressure with better boost control and more power.


Note that the external wastegate is sold separately. 




  • Capable of supporting up to 600 HP
  • Each GTX drop-in turbo package consists of a Garrett factory assembled and high speed balanced dual-ball bearing CHRA
  • New high flowing 11-blade next generation compressor wheel
  • Assembled into a set of CNC machine ported housings that have been optimized in every aspect for maximum flow and efficiency
  • 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
  • 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
  • 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
  • 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 3-inch downpipe and bigger inlet is critical for reaching peak efficiency on the GTX turbo
  • Includes spacer, however, 2 up-pipe gaskets will be needed if using the included spacer
  • Not compatible with the twin-scroll up-pipe flange
  • External wastegate not included and sold separately 
  • - Left Hand Drive and Right Hand Drive chassis compatible. Right Hand Drive chassis requires external wastegate relocation elbow.
    - EJ20 and EJ25 (stock open scroll flange and location) platform compatible. Twin-scroll up-pipe flange is NOT compatible.
    - 2008 - 2014 WRX's requires either (A) aftermarket top mount intercooler with a hose connection to the compressor outlet; or (B) a front mount intercooler
