Garrett 952766-5005S G-XRace GXR45-82 82mm Supercore Turbocharger Racing 1800HP

Vehicle Fitment

• Universal Fit - Not application-specific. Compatible with any engine platform where a GXR45-frame turbocharger can be fitted. Turbine housing sold separately.

Fitment Notes

• This is a Supercore only - a complete turbine and compressor assembly without a turbine housing. A GXR45-compatible turbine housing must be purchased separately to complete the turbocharger unit.
• The GXR45 Supercore uses the same twin-scroll T4 divided and V-Band turbine housings as the Garrett G-Series G45, enabling a direct drop-in supercore upgrade for existing G45 builds.
• Turbine housing A/R options: 1.01, 1.15, 1.28, and 1.44 - available in stainless steel with T4 divided or V-Band turbine inlet flanges (sold separately).
• Designed for racing use only. Not legal for use on public roads. Not CARB compliant.
• Compatible with Garrett speed sensors PN 781328-0003 and 781328-0004, and the G-Smart Bluetooth Module PN 923586-0003 (sold separately).
• Maximum allowable turbocharger speed: 100,000 RPM. Operation above this limit is at the owner's risk.

Features

• Patent-pending XBoost Technology delivers up to +29% increase in compressor flow compared to the G-Series line (depending on model and frame size)
• 82.9mm compressor inducer is the largest in the GXR45 lineup, providing maximum airflow capacity and the highest power ceiling of the GXR45 Supercore family
• Increased pressure ratio capability enables operation at significantly higher boost levels versus G-Series predecessors
• Improved compressor efficiency at high flow rates produces cooler, denser intake charge for greater power density
• Lightweight aluminum backplate reduces overall turbocharger weight compared to traditional cast designs
• Flanged speed sensor port simplifies installation and allows direct monitoring of turbine shaft speed
• Interchangeable with existing G45 G-Series turbine housings - enables direct supercore swap without manifold or housing changes
• Inconel turbine wheel construction for extreme heat resistance and fatigue durability under sustained high-power operation
• Dual ceramic ball bearing center section for reduced friction, faster spool response, and extended service life
• Compatible with Garrett G-Smart Bluetooth Module for real-time turbo speed monitoring and boost data logging

Product Description

The Garrett 952766-5005S is the GXR45-82 Supercore - the largest and most powerful variant in Garrett's GXR45 G-XRace Supercore lineup. With an 82.9mm compressor inducer, 109mm exducer, and Inconel turbine wheel, the GXR45-82 is rated to support up to 1,800 HP, representing the top of the GXR45 family's power range. Built around Garrett's patent-pending XBoost Technology, the G-XRace line delivers up to +29% more compressor flow over comparable G-Series turbos, raises the pressure ratio ceiling for elevated boost operation, and improves efficiency at peak flow rates to deliver cooler, denser charge air - all in a package that retains direct compatibility with the proven G45 turbine housing ecosystem.

The GXR45-82 shares the same frame and turbine housing interface as the Garrett G-Series G45, meaning existing G45 builds can be upgraded to this top-spec supercore without altering their manifold, downpipe, or turbine housing. Turbine housings in T4 divided or V-Band configurations with A/R ratios of 1.01, 1.15, 1.28, and 1.44 are sold separately to accommodate varying manifold designs and boost curve requirements. The dual ceramic ball bearing center section delivers fast spool response and reduced rotational friction, while the flanged turbine speed sensor port allows straightforward instrumentation. Water fittings are included with the supercore for water-cooled center housing configurations.

This is a Supercore - the rotating assembly and center housing only, without a turbine housing. A compatible GXR45 turbine housing must be sourced separately to complete the turbocharger unit. For builders seeking real-time performance data, the GXR45-82 supports optional integration with Garrett's G-Smart Bluetooth Module (PN 923586-0003) and compatible speed sensors (PN 781328-0003 or 781328-0004) - all sold separately. This product is intended exclusively for closed-course racing applications and is not legal for road use.
