STEALTH MACH 1 (64) TURBO (2001-2004 6.6L LB7 DURAMAX)

The LB7 Stealth 64 Turbo is the best drop-in style, LB7 turbocharger available on the market today. It’s a direct bolt-on stock replacement that offers unique features not found elsewhere.

This turbocharger is designed for your 2001, 2002, 2003, or 2004 LB7 6.6L Duramax engine. It improves power output, enhances towing performance, and overall increases the vehicle’s performance.

We achieve this through a custom-designed high-flow turbine assembly and a 7075 billet compressor wheel. All these components are housed in a liquid-cooled package protected by 360-degree thrust bearings.

One of the key advantages of the LB7 Stealth 64 Turbo is its larger turbine assembly. This design allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load results in increased efficiency and power at a given boost level. Consequently, you’ll experience lower EGTs under heavy load.

Overall, the LB7 Stealth 64 Turbo delivers peak power of 640HP, pushing the boundaries of what’s possible with a stock-appearing, bolt-in IHI-style turbocharger. It’s a truly exceptional performance upgrade that offers a unique combination of features and capabilities.
