What changed with G-Series II

• New compressor aerodynamics: up to 10% more compressor flow than the first G-Series at peak pressure ratio and peak turbo speed
• Better efficiency at high flow rates
• Same compressor and turbine housings as the first generation, so it is a direct upgrade for a first-generation G-Series turbo
• Mar-M alloy turbine wheel and stainless steel turbine housing, both rated to 1050°C

The engine needs a new calibration (tune) to turn the extra airflow into horsepower. Garrett builds the G-Series II in standard and reverse rotation; check the part number against your setup before ordering.
