The Garrett G42-1200C Compact CHRA is built for enthusiasts pushing gasoline engines to extreme boost levels without sacrificing throttle response. Its dual-ball bearing architecture and compact 42mm wheel design make it the choice for builders who demand both high-end power capacity and a turbo that spools cleanly across a wide RPM band. This is a core assembly for serious, heavily modified builds where compromise isn’t an option.

Performance & Application

This compact CHRA is engineered for heavily modified gasoline engines that require aggressive turbo response paired with high-flow efficiency. The dual-ball bearing design delivers responsive spool-up across a wide RPM range, giving builders the best of both worlds: quick-spooling low-end response and the durability to handle extreme boost. It’s suited for high-horsepower gasoline applications where both drivability and top-end capacity matter.
