Performance & Application

This CHRA is engineered for forced-induction applications demanding tight packaging without compromising turbo response. The ball-bearing construction provides quick spool-up characteristics well suited to street and modified engine platforms. Reverse rotation configuration makes this core assembly ideal for builds where standard compressor orientation isn’t compatible with the intended layout. It fits within Garrett’s G30-900 platform, giving builders access to G Series performance in a reverse-rotation format.
