TAKE YOUR SUBARU TO THE NEXT LEVEL WITH A GRIMMSPEED TURBOCHARGER!
The GrimmSpeed Turbocharger Program started by recognizing a need in the market for a robust, quick-spooling and high-performing turbo. Design began from the ground up and took over 3 years of hard work, testing and development to introduce a product that we're proud to have carry The GrimmSpeed Name. The focus of this project was to offer a stock location OE replacement turbo, which when paired with GrimmSpeed supporting mods, allows enthusiasts to take full advantage of their EJ series turbo engine.
Both of our new turbocharger options feature state of the art proprietary compressors, turbines, CHRA's and wheel designs which maximize the power made on your EJ engine at two different price points. The overall design went through tedious gas flow test analysis, strenuous failure testing and engine pounding dyno/road testing, all to create the new standard for EJ engines: The GrimmSpeed Chase JB400 and Overtake BB500 Turbochargers!
