Garrett 953234-5009S G-XRace GXR50-80 XBoost Supercore 80mm/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
• 80mm/120mm configuration - the GXR50-80 features a 120mm compressor exducer, which is larger than the 109mm exducer used on the standard G-Series G50-1700 (80mm), providing greater peak flow potential
• 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 high airflow levels versus the G-Series G50 baseline
• 80mm compressor inducer / 120mm compressor exducer - larger exducer than the standard G50-1700 80mm variant, maximizing peak compressor flow within the G50 frame at the 80mm inducer size
• 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 at extreme boost levels
• 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
• G50 turbine frame supports up to 11.0L engine displacement - 1.0L more than the G47 frame

Product Description

The Garrett 953234-5009S is the GXR50-80 supercore from the G-XRace series - an 80mm inducer variant built on the G50 turbine frame with XBoost compressor aerodynamics. Unlike the standard G-Series G50-1700, which pairs the 80mm inducer with a 109mm exducer, the GXR50-80 uses a larger 120mm exducer, delivering greater peak compressor flow potential alongside the XBoost efficiency and pressure ratio gains. Combined with the G50's larger turbine stage (99mm/94mm, supporting up to 11.0L engine displacement), this makes the GXR50-80 a capable option for high-power builds requiring an 80mm inducer with the capacity of the G50 turbine frame.

The GXR50-80 is supercore-only and is interchangeable with all G-Series G50 turbine housings (T6 inlet, 0.96-1.39 A/R), making it a straightforward drop-in upgrade for existing G50 builds. The G50 turbine stage delivers up to 23% more turbine flow than the GTX50. A machined speed sensor port is included for optional shaft speed monitoring. Turbine housing, speed sensor, and installation hardware are sold separately.
