Garrett 934174-5013S G-XRace GXR57-94 XBoost Supercore 94mm/149mm Racing Turbo

Vehicle Fitment

• Universal - compatible with professional motorsport and drag racing applications on 3.0L-12.0L engine platforms; requires a compatible G-Series G57 turbine housing

Fitment Notes

• Supercore only - a G-Series G57 turbine housing is required and sold separately; available in three V-Band stainless steel housings at 1.09 A/R, 1.25 A/R, and 1.41 A/R
• G-XRace GXR57 supercores use the same G57 turbine housings as the G-Series G57 platform - direct upgrade from a G57 supercore without changing the turbine housing or exhaust hardware
• 94mm compressor inducer - the mid-range option in the GXR57 lineup, between the GXR57-88 and GXR57-98, for builds targeting a specific inducer size or power band within the G57 frame
• Designed for professional motorsport and extreme 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: 84 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 enhanced compressor flow beyond the G-Series G57 platform, with improved pressure ratio capability and greater efficiency at extreme airflow levels
• 94mm compressor inducer / 149mm compressor exducer - balances spool response and peak flow for extreme drag racing and high-power motorsport builds within the G57 turbine frame
• Built on Garrett's G57 turbine frame: 118mm / 112mm Inconel turbine wheel delivering 28% more turbine flow than the GTX Gen II platform
• 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 G57 V-Band turbine housings - seamless upgrade from G57 without changing exhaust hardware
• Designed for Radial vs. the World, extreme drag racing, and other top-level competition motorsport applications

Product Description

The Garrett 934174-5013S is the GXR57-94 supercore from Garrett's G-XRace series - the 94mm inducer variant of the GXR57 platform, released in May 2026 alongside the GXR57-88 and GXR57-98. Built on the G57 turbine frame with XBoost compressor aerodynamics, the GXR57-94 delivers increased compressor flow and enhanced pressure ratio capability beyond the standard G-Series G57, combining the higher-flowing 149mm exducer with a 94mm inducer that strikes a balance between boost response and top-end airflow capacity. It is well-suited for extreme drag racing and large-displacement race engine builds where a mid-range compressor inducer size is preferred within the GXR57 lineup.

The GXR57-94 is supercore-only and is interchangeable with all G-Series G57 V-Band turbine housings (1.09, 1.25, or 1.41 A/R), making it a direct drop-in upgrade for builders already on the G57 platform. The G57 turbine stage - featuring a 118mm/112mm Inconel wheel with 28% more flow than GTX Gen II - provides the exhaust energy extraction capacity to support the GXR57's expanded compressor aero at extreme power levels. A machined speed sensor port is included for optional overspeed monitoring. Turbine housing, speed sensor, and installation hardware are sold separately.
