Mach 2 67mm VGT Turbocharger

The Stealth Mach 2 67mm VGT Turbo is a high-performance, drop-in replacement turbocharger for 2017-2023 Chevrolet and GMC 6.6L Duramax L5P and 2019+ L5D engines. This unit is designed to be a 100% stock-appearing upgrade that bolts directly in place of your factory turbo. Featuring Calibrated Power Solutions' proprietary High Flow Vane (HFV) Technology, this turbo utilizes a custom nozzle ring assembly to achieve faster spool-up and higher flow rates. The 67mm, 11-blade extended tip billet 2618 aluminum alloy compressor wheel offers a wide efficiency range, and the oversized 70.4mm, 9-blade 713C nickel alloy turbine wheel contributes to a distinctive exhaust note and improved high-load efficiency. This turbo provides 81 lbs/min of airflow, compared to the stock 60 lbs/min, and is capable of supporting up to 800 RWHP with extensive supporting modifications. This turbocharger is designed to maintain low drive pressures at high loads, which helps in better Exhaust Gas Temperature (EGT) control and nearly a 1:1 drive to boost ratio under most operating conditions. It also retains the factory exhaust brake functionality and offers quicker throttle response. The Stealth Mach 2 is built from brand new parts and includes a 12-month warranty. The actuator is sold separately, and the manufacturer notes that the factory actuator often has a low failure rate and may not need replacement unless experiencing specific codes or damage. This turbo upgrade is recommended for those who daily drive their truck, prioritize reliability and performance, tow with their vehicle, and desire more power while maintaining excellent street manners. It is strongly suggested to pair this turbo with custom tuning to achieve optimal performance, with up to 650 RWHP achievable with emissions-compliant tuning and basic supporting modifications.
