Garrett G-XRace GXR50-88 88.9/123mm Supercore Turbocharger
The Garrett G-XRace GXR50-88 Supercore (953234-5010S) is a next-generation high-performance turbocharger supercore engineered for extreme power applications ranging from 500 to 2,050+ horsepower.
Featuring advanced XBoost aerodynamics, this supercore delivers significantly increased airflow, faster spool, and higher efficiency compared to previous generations.
With an 88.9mm compressor inducer and massive 123mm exducer paired with a 99mm turbine inducer / 94mm exducer, the GXR50-88 is capable of supporting massive power levels on engines from 2.5L to 11.0L.
The lightweight aluminum backplate reduces overall turbo weight, while the flange-style speed sensor port allows easy integration of turbo speed monitoring for precise tuning and engine protection.
Sold as a supercore (compressor and turbine section only), it gives builders the flexibility to choose the perfect turbine housing for their specific engine and power goals. Ideal for drag racing, high-horsepower street builds, and competition vehicles, the GXR50-88 sets a new benchmark in turbo performance.
