Description
Part Number 773540-5001S (590HP*) Stage 1
Applications: 2004.5-2009 Chevy / GMC 2500, 3500
The Duramax Stage 1 turbocharger kit features Garrett patented Advanced Variable Nozzle Turbine AVNT™ design for increased compressor and turbine flow. The GT Series wheel design ensures top performance, lower back pressure, and reduces intake and exhaust gas temperatures. The unique design features nine movable vanes which significantly increase turbine efficiency and improve engine performance from idle launch through peak torque. Patented integral electro-hydraulic actuation and proportional solenoid allow for infinitely variable control. Suitable as a performance upgrade or replacement for original equipment. Outline interchangeable with the OE turbo for perfect fit each and every time.
Part Number 773542-5001S (630HP*) Stage 2
Applications: 2004.5-2009 Chevy / GMC 2500, 3500
The Duramax Stage 1 turbocharger kit features Garrett patented Advanced Variable Nozzle Turbine AVNT™ design for increased compressor and turbine flow. Utilizes nine movable vanes which significantly increase turbine efficiency and improve engine performance from idle launch through peak torque. Patented integral electro-hydraulic actuation and proportional solenoid allow for infinitely variable control. Larger compressor trim (52), plus larger GT40 turbine wheel and vanes. Outline interchangeable with the OE turbo for perfect fit each and every time.
*Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The target power has been calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel power.
PowerMax™ direct fit performance turbocharger kits are engineered for enthusiasts that want increased engine performance while maintaining OEM direct fitment. With professional engine calibration and tuning, the optimized compressor aero will increase flow and outperform the stock turbocharger. These products are not approved for street use. Installation may affect the vehicle’s safety, warranty, and operating license.
