Garrett 953234-5008S G-XRace GXR50-76 XBoost Supercore 76mm/120mm Racing Turbo

Vehicle Fitment

• Universal - compatible with high-performance motorsport and drag racing applications on 2.5L-11.0L engine platforms; requires a compatible G-Series G50 turbine housing

Fitment Notes

• Supercore only - a G-Series G50 turbine housing is required and sold separately; available in T6 inlet stainless steel housings at 0.96, 1.08, 1.23, and 1.39 A/R
• G-XRace GXR50 supercores use the same G50 turbine housings as the G-Series G50 platform - direct upgrade without changing existing exhaust hardware
• All G-Series G50 supercore configurations are interchangeable within the same turbine housings - swap supercores without reconfiguring other turbo kit components
• 76mm compressor inducer on the G50 turbine frame - this inducer size is exclusive to the GXR50 lineup and is not available in the standard G-Series G50, making this a unique option for builds needing a smaller inducer on the G50's larger turbine stage
• Designed for professional motorsport and high-performance competition - not for street use on public roads
• Speed sensor port machined into compressor housing - compatible with p/n 923586-0003 (G-Smart Bluetooth Module), 781328-0003 (street kit with gauge), or 781328-0004 (pro kit without gauge), all sold separately
• Maximum allowable turbocharger speed: 93 krpm - use above this speed is at owner's risk
• Not CARB legal - for competition and off-road race use only; not for sale in California

Features

• XBoost technology delivers increased compressor flow, enhanced pressure ratio capability, and improved efficiency at elevated airflow levels versus the G-Series G50 baseline
• 76mm compressor inducer / 120mm compressor exducer on the G50 frame - unique configuration not available in the standard G-Series G50, enabling faster spool response with the G50's larger turbine stage
• G50 Inconel turbine wheel: 99mm inducer / 94mm exducer (90 trim) - delivering up to 23% more turbine flow than the GTX50 turbine wheel
• Lower intake temperatures via XBoost compressor efficiency for denser charge air and more power potential
• Lightweight one-piece aluminum backplate reduces overall supercore weight
• Fully machined flange-style speed sensor port for turbo shaft speed monitoring and overspeed protection
• Compatible with all G-Series G50 turbine housings - seamless upgrade from G50 without changing exhaust hardware
• Combines the spool characteristics of a smaller 76mm compressor inducer with the high-flow turbine capacity of the G50 frame

Product Description

The Garrett 953234-5008S is the GXR50-76 supercore from the G-XRace series - a unique configuration that pairs XBoost compressor aerodynamics with a 76mm inducer on the G50 turbine frame. This inducer size is not available in the standard G-Series G50 lineup (which offers only 80mm and 88mm inducers), making the GXR50-76 a distinctive option for builders who want the faster spool and lower-boost response of a smaller 76mm compressor inducer combined with the high-flow turbine capacity and larger displacement support (up to 11.0L) of the G50 turbine stage.

The XBoost compressor delivers increased flow and enhanced pressure ratio capability beyond the G50 baseline, while the 120mm exducer provides a wide operating range. The GXR50-76 is supercore-only and is interchangeable with all G-Series G50 turbine housings (T6 inlet, 0.96-1.39 A/R), enabling a direct swap for existing G50 builds. The G50 turbine stage features a 99mm/94mm Inconel wheel with up to 23% more turbine flow than the GTX50. Turbine housing, speed sensor, and installation hardware are sold separately.
