• Turbine Wheel Exducer: 94mm
• Garrett P/N: 953234-5009S

Performance & Application

This Supercore forms the core of the Garrett G-XRace50 series, built for high-boost applications where wheel design and airflow precision are critical. Because it’s supplied as a Supercore, builders select the turbine housing to complete the unit, allowing the turbo’s spool characteristics and top-end flow to be tailored to the specific engine and power target. This flexibility makes it a preferred option for shops and enthusiasts assembling a purpose-built turbo system rather than relying on a fixed off-the-shelf configuration.

Compatibility & Fitment

• Requires a turbine housing to complete the turbo unit — the G-XRace50 uses the same turbine housing as the G-Series G50 turbo

Frequently Asked Questions
