Subaru EJ20/EJ25 Twin Scroll EFR T4 EWG Turbo Kit

Subaru EJ20/EJ25 Twin Scroll EFR T4 EWG Turbo Kit

This is our top selling Subaru turbo kit, and it’s no stranger to breaking records. Jager Racing took 1st place in the 2016 Unlimited AWD Global Time Attack Championship with this off-the-shelf Full-Race Turbo Kit.

Our 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 recommends 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.
