Performance & Application
This supercore is engineered as the foundation of the GX-Race50 turbocharger platform, intended for builders assembling a complete turbo unit for extreme performance applications. A turbine housing must be added separately to complete the turbo assembly, and the G-XRace50 shares turbine housing compatibility with the G-Series G50 turbo, giving builders flexibility in sourcing a matching housing. This configuration is built for those who need precise control over turbine housing selection to tailor spool characteristics and top-end flow to their specific build goals.
Compatibility & Fitment
- Uses the same turbine housing as the Garrett G-Series G50 turbo
