Calibrated Power - 2001-2004 LB7 Duramax Stealth Mach 1 63/67 Drop In Turbo - CPS200226

Supports up to 640RWHP! The BEST drop-in style, LB7 turbo on the market today!

The LB7 Stealth Mach 1 Turbo is a direct drop-in, bolt-on stock appearing replacement with features you won’t find anywhere else. Your 2001, 2002, 2003, or 2004 LB7 6.6L Duramax will have improved power, perform better while towing and experience overall increased performance.  This is capable through the use of a custom-designed high-flow turbine assembly and 7075 billet compressor wheel. The Stealth Mach 1 does all this in a liquid-cooled package protected by 360-degree thrust bearings.

The larger turbine assembly allows for lower drive pressure, creating a better balance between boost and drive (exhaust backpressure). This improved balance under heavy load means more efficiency and power at a given boost number, resulting in lower EGTs under heavy load. Overall peak power is also improved, the LB7 Stealth Mach 1 pushes the envelope to 640HP. You’re not going to find all of these features anywhere else in the aftermarket in a truly stock-appearing, '64mm class' bolt-in IHI-style turbocharger.

To complement this turbo we highly recommend a WCFab LB7 Stage 3 High Flow Intake Bundle Kit (WCF100712) to maximize performance, EGT control, and spool up. Looking for more yet? Add the Mach 1 to a WCFab S400/Stock Compound kit and you've got the recipe for 1000 RWHP. 

This Turbo is Designed for you if:
- You daily drive your truck
- Reliability & Performance are Top Priority
- You tow with your truck
- You prefer to simply swap your old turbo out for a new one
- You want more power when you need it, but still have excellent street manners!
