Product Resources
Features & Product Details
RallySPort Direct proudly carries a great selection of quality performance upgrades by our friends over at GrimmSpeed.
This is GrimmSpeed's new CHASE JB400 Turbocharger. Designed by Chase Trogan who is a senior engineer at GrimmSpeed, this particular turbocharger is the result of over 3 years of testing and development. GrimmSpeed's goal was to provide a mid-sized turbocharger that offers many power benefits at a good price point. This turbocharger has a proprietary and state-of-the-art compressor, turbine, CHRA, and wheel design. These features have enabled GrimmSpeed to take full advantage of the physical limitations of the EJ's engine bay, and the design has endured tedious flow analysis, strenuous failure testing, and engine-pounding road and dyno testing.
The JB400 is the perfect addition to any Stage 3 car as the flow characteristics have been designed to pair well with the stock fuel system. The severe-duty journal bearing has been built to last, and even with minor upgrades, this turbocharger will substantially change the power characteristics and delivery of the EJ engine. This turbo quickly responds but delivers the punch from mid to the top-level RPM range. It will keep the power up between shifts while maintaining a flat power curve.
