Product Description

The Garrett 934117-5002S G30-825 G-Series II Supercore represents the latest evolution in Garrett's motorsport-proven turbocharger technology. Designed for custom and high-performance applications, this Supercore delivers outstanding response and efficiency across a wide range of displacement and boost targets.

The G-Series II platform incorporates an all-new compressor aerodynamics package capable of supporting up to 825 horsepower while maintaining exceptional transient response. Its compact dual-ceramic ball bearing center housing rotating assembly (CHRA) provides reduced friction and longer service life, making it ideal for endurance builds or professional motorsport use. The Supercore configuration allows builders to pair it with the appropriate G30 turbine housing (available separately) for maximum flexibility.

This Supercore is intended for experienced tuners and fabricators who require a versatile high-flow turbo foundation. It is not a direct bolt-on replacement but a precision-engineered modular unit that forms the core of a custom G-Series turbo system.
