Overview

The Garrett G30-825 Reverse Rotation G-Series II Supercore is a high-performance turbocharger designed for custom applications. It features new compressor aero technology for increased power and performance, offering up to 10% higher compressor flow compared to the G-Series Gen I at peak pressure ratio and peak turbo RPM. This supercore is a direct upgrade path for Gen I customers and utilizes Gen I compressor and turbine housings. Calibration is required to take advantage of the increased flow for a horsepower upgrade. It boasts increased efficiency at high flow rates and is available in standard and reverse rotation configurations. The turbocharger uses a Mar-M alloy turbine wheel rated up to 1050° C and stainless steel turbine housings also rated up to 1050° C. It is water and oil cooled and features dual ceramic ball bearings, four large water jacket ports, and twin piston rings at the compressor and turbine side.
