Garrett 953234-5010S G-XRace GXR50-88 XBoost Supercore 88mm/120mm Racing Turbo

Vehicle Fitment

• Universal - compatible with custom racing applications using G50-frame turbine housings; supports 2.5L-11.0L engine displacements in professional motorsport builds

Fitment Notes

• Supercore only - requires a separate G-XRace GXR50 or G-Series G50 turbine housing (sold separately); T6 and V-Band housing options available in 0.96, 1.08, 1.23, and 1.39 A/R
• Compatible with G-Series G50 turbine housings - all G50 supercores are interchangeable within the frame
• Speed sensor port requires separate speed sensor: p/n 781328-0003 (sensor + gauge), 781328-0004 (sensor only), or G-Smart Bluetooth Module p/n 923586-0003 (all sold separately)
• Not CARB legal - for competition and off-road race use only; not for street use in California or where emissions regulations apply
• Operating above maximum turbocharger speed is at the owner's risk and may result in damage or premature failure

Features

• XBoost technology delivers increased compressor flow, enhanced pressure ratio capability, and higher efficiency at high airflow levels versus G-Series G50
• 88mm compressor inducer / 120mm compressor exducer - maximum compressor size in the G50 frame for the highest power potential
• G50 Inconel turbine wheel: 99mm inducer / 94mm exducer - 90 trim turbine wheel engineered for extreme exhaust energy recovery
• Lower intake temperatures via improved compressor efficiency for denser charge air and higher power density
• Lightweight one-piece aluminum backplate reduces supercore weight for optimized packaging in race applications
• Fully machined flange-style speed sensor port for precise turbo shaft speed monitoring
• Supercore swap-ready within G50 frame - turbine housing can be changed without reconfiguring other turbo kit components
• Designed for professional motorsport use in drag racing, time attack, and high-power circuit competition

Product Description

The Garrett 953234-5010S is the GXR50-88 supercore from the G-XRace series - Garrett's top-tier motorsport compressor stage designed for professional racing teams competing in high-horsepower classes. Built on the G50 turbine frame with an 88mm compressor inducer and 120mm exducer, the GXR50-88 leverages XBoost technology to push beyond the airflow and pressure ratio limits of the standard G-Series G50, making it the choice for builds demanding every fraction of available power from large-displacement engines.

The GXR50-88 is sold as a supercore only and is interchangeable with all G-Series G50 and G-XRace GXR50 turbine housings, allowing builders to retain their existing exhaust housing when upgrading from a G50. The flange-style speed sensor port is machined into the compressor housing to support turbo speed monitoring - a critical overspeed protection measure for high-boost race applications. Turbine housings, speed sensors, and installation hardware are sold separately.
