CALIBRATED POWER STEALTH MACH 2 (67MM) TURBOCHARGER CPS200368 | 2001-2004 6.6L DURAMAX LB7

Upgrade your GM 6.6L Duramax LB7 with the Calibrated Power Stealth Mach 2 67mm Turbocharger. Designed as a direct-fit performance replacement, the Mach 2 combines increased airflow with quick spool characteristics and a broad torque curve while retaining a clean, factory-style appearance.

At the center of the Stealth Mach 2 is a custom 67mm x 96mm billet compressor wheel paired with an engineered anti-surge compressor cover. This combination is designed to increase airflow while improving compressor stability at higher boost levels, helping support strong and consistent performance throughout the RPM range.

On the exhaust side, Calibrated Power utilizes a 77mm x 71mm Stealth High-Flow turbine assembly engineered to improve exhaust flow and efficiency. An updated wastegate configuration helps promote quicker spool-up and responsive boost characteristics, providing usable power without sacrificing everyday drivability.

The Mach 2 also incorporates 360-degree thrust bearings to improve durability during heavy-load transitions and demanding performance applications. Together, these upgrades provide a turbocharger capable of supporting up to 800 peak horsepower while delivering a wide torque curve and responsive power delivery.
