It’s official, we now recommend using the ETS STI turbo kit over the Full Race turbo kit. After years of running both kits on our shop builds with great success ETS has edged ahead and is now making more power throughout the RPM range when compared to the Full Race kit.

The Full-Race engineers have out done them selves with the Gen2 EJ25/EJ20 Twin Scroll turbo kit. The new design provides more air flow, less weight, fits multiple generation Subaru chassis and most importantly – generates a nice wide torque friendly power band with huge area under the curve. The T4 twin scroll turbo kit consists of all the necessary turbocharger hot side upgrade components, and utilizing ideal cylinder pairing and the proper implementation of twin scroll technology.

Full-Race engineered these kits to offer optimal performance with instant throttle response, early spool and huge top-end power – while being flexible enough to grow with your future needs and changes in driving style. Full-Race recommends using T4 frame turbochargers such as BorgWarner EFR, Airwerks, or Garrett, PTE or FP, etc. The EFR series turbos have proven to be an outstanding match on the EJ25 engine with tons of size options to choose from and a friendly price point. 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.
