Calibrated Power Stealth MACH-1 64mm Drop-In VGT Turbo – 2011–2016 GM 6.6L LML Duramax

Part Number: CPS200262

Upgrade the power, towing performance, and drivability of your 2011–2016 Chevrolet Silverado or GMC Sierra 6.6L LML Duramax with the Calibrated Power Stealth MACH-1 64mm Drop-In VGT Turbo. Designed as a direct bolt-on replacement for the factory turbocharger, the Stealth MACH-1 delivers substantially increased airflow while retaining quick spool-up, responsive street manners, and full variable-geometry turbo operation.

The 64mm extended-tip, 11-blade billet compressor wheel is precision-machined from high-strength 2618 aluminum alloy for excellent airflow, efficiency, and durability. On the exhaust side, a 66.5mm 9-blade turbine wheel constructed from heat-resistant 713C nickel alloy improves exhaust flow and helps reduce drive pressure and exhaust gas temperatures under load.

Capable of supporting more than 650 rear-wheel horsepower with the proper tuning and supporting modifications, this LML Duramax turbo is an excellent upgrade for daily driving, towing, street performance, and modified diesel applications. Its broad operating range provides strong low-end response with improved top-end power, giving your Duramax the airflow it needs without sacrificing everyday drivability.

The Stealth MACH-1 installs in the factory turbo location and utilizes the stock downpipe and oil fittings for a straightforward installation. A heavy-duty 360-degree thrust bearing provides increased durability, while the upgraded compressor and turbine combination produces the pronounced Stealth turbo whistle diesel enthusiasts want.
