Subaru EJ20/EJ25 AirWerks Twin Scroll AirWerks T4 EWG Turbo Kit
This turbo kit isnt for everyone. It works best on a built motor, and more work to install than a stock location turbo. However – it is our top selling turbo kit, and we snagged the 2016 Unlimited AWD Global Time Attack championship with an off-the-shelf setup.
Full-Race engineers designed this kit to generate the broadest possible power band with huge area under the curve. This is not intended to go 8s in the quarter mile. Optimal performance with fast throttle response, early spool and huge top-end power – while being flexible enough to grow with your future needs. Full-Race recomends using T4 frame turbochargers such as BorgWarner Airwerks, EFR, or Garrett, Turbonetics, etc. The S300SX FMW has proven to be an outstanding high power performer on the EJ25 engine.
Whether you are road racing, drag racing or building a “street weapon” daily driver, the Full-Race Twin Scroll Turbo Kit is adaptable to suit any chassis and application, now including the popular 08+ STI and 05+ Legacy GT and 11+ STI.
