Performance & Application

This CHRA is purpose-built for Gen I G-Series owners seeking a direct upgrade path, whether purchased as a complete turbo unit, a supercore, or as a standalone CHRA. Because it retains compatibility with existing Gen I compressor and turbine housings, it allows builders to upgrade internals while reusing proven housing hardware. The result is increased efficiency at high flow rates, giving serious builds more headroom without sacrificing the durability G-Series is known
