Garrett G-XRace 76.6/123mm Supercore Turbocharger (Part 953234-5006S)
The Garrett G-XRace Supercore (953234-5006S) represents the next generation of high-performance turbochargers from Garrett. Featuring advanced XBoost aerodynamics, this supercore delivers significantly increased power, efficiency, and a wider usable flow range compared to previous G-Series models.
With a 76.6mm compressor inducer and massive 123mm exducer paired with a 93mm turbine inducer / 88mm exducer, the GXR47-76 is capable of supporting 500 to 1,700+ horsepower on engines ranging from 2.5L to 10.0L.
The lightweight aluminum backplate reduces overall turbo weight while the machined speed sensor port allows easy integration of turbo speed monitoring for precise tuning and engine protection.
Sold as a supercore (compressor and turbine section only), it gives builders complete flexibility to choose the ideal turbine housing for their specific application. Whether you’re building a drag car, high-horsepower street machine, or competition vehicle, the GXR47-76 offers record-setting performance with the reliability Garrett is known for worldwide.
