Subaru EJ20/EJ25 AirWerks Twin Scroll AirWerks T4 EWG Turbo Kit

This turbo kit isn't 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 Unlimited AWD Global Time Attack championship with an off-the-shelf setup. Full-Race engineers designed this kit to generate the broadest possible powerband with huge area under the curve. This is not intended to go 8s in the quarter-mile (but it can). 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 recommends using T4 frame turbochargers such as BorgWarner Airwerks, EFR, or Garrett, Precision, etc. The S300SX-E has proven to be an outstanding high power performer on the EJ25 engine. Whether you are road racing or drag racing, 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.
