TAKE YOUR SUBARU TO THE NEXT LEVEL WITH A GRIMMSPEED TURBOCHARGER!
Introducing the JB400 and BB500 Turbos:
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!
Introducing The GrimmSpeed Overtake BB500. This turbocharger features world class power delivery and quick spool characteristics. It remains a stock location EJ turbo, but features a larger 55lb compressor wheel and massive 60mm turbine wheel to allow the engine to really breathe at high RPM. Just like with the Chase JB400, drivability was our #1 goal and by combining slick aero wheel designs with a dual ceramic ball bearing center housing rotating assembly, we were able to achieve superior spool results. This allowed us to hit 20PSI BEFORE 4100RPM and out-spool our well-performing Chase turbo by an impressive 150 RPM! When bolted onto our 2020 STI Shop Car, we were able to produce 488WHP and 515WTQ. However, the most impressive part is that the Overtake Turbocharger is able to hold 400WTQ+ from 4000RPM and hold over 400WHP from 4250RPM all the way to Redline! The design philosophy was to keep the turbo in its powerband after shifts and to hold substantially more power than the stock turbo to redline. The Overtake produces 129 horsepower and 109 ft/lbs of torque over a tuned stock STI turbo. This is all accomplished on a vehicle with only simple bolts-on, cars with additional engine work such as cams, intake manifolds, etc will be able to produce even higher gains!
