Garrett 953234-5006S G-XRace GXR47-76 XBoost Supercore 76mm/120mm Racing Turbo

Vehicle Fitment

• Universal - compatible with high-performance motorsport and drag racing applications on 2.5L-10.0L engine platforms; requires a compatible G-Series G47 turbine housing

Fitment Notes

• Supercore only - a G-Series G47 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 GXR47 supercores use the same G47 turbine housings as the G-Series G47 platform - direct upgrade from a G47 supercore without changing the turbine housing or exhaust hardware
• All G-Series G47 turbine housings are interchangeable across all GXR47 supercore configurations - swap supercores without reconfiguring other turbo kit components
• 76mm/120mm configuration - the larger-exducer GXR47-76 variant; note a separate 76mm/109mm Ultra Street variant is also available and uses a different compressor housing
• Designed for professional motorsport and high-performance drag racing 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: 102.5 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 G47 baseline
• 76mm compressor inducer / 120mm compressor exducer - the large-exducer GXR47-76 configuration for builds requiring higher peak flow from the 76mm inducer
• G47 Inconel turbine wheel: 93mm inducer / 88mm exducer (90 trim) - delivering up to 20% more turbine flow than the GTX47 turbine wheel
• Lower intake temperatures via XBoost compressor efficiency for denser charge air and improved 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 G47 turbine housings - seamless upgrade path from G47 without changing exhaust hardware
• Engineered for extreme drag racing, time attack, and other high-power competition motorsport on 2.5L-10.0L engine platforms

Product Description

The Garrett 953234-5006S is the GXR47-76 supercore from the G-XRace series - the large-exducer (120mm) variant of the GXR47-76 built on the G47 turbine frame. By applying XBoost compressor aerodynamics to the G47 platform, this supercore delivers increased compressor flow and enhanced pressure ratio capability beyond the G-Series G47 baseline, making it well-suited for race builds targeting the highest power levels achievable from a 76mm compressor inducer within the G47 turbine frame. The 120mm exducer provides greater peak flow potential compared to the 109mm-exducer Ultra Street variant, optimizing the supercore for high-load, high-RPM competition applications.

The GXR47-76 (953234-5006S) is supercore-only and is interchangeable with all G-Series G47 turbine housings across all four available A/R options (0.96, 1.08, 1.23, 1.39), making it a direct drop-in upgrade for builders already running a G47 setup. The G47 turbine stage features a 93mm/88mm Inconel wheel delivering up to 20% more flow than the GTX47 turbine wheel. A machined speed sensor port is included for optional overspeed monitoring. Turbine housing, speed sensor, and installation hardware are sold separately.
