Duramax Tuner Stealth Mach 2 (67mm) Drop In Turbo 01-04 GM LB7 Duramax

Building the line of Stealth Turbos meant designing a turbo that's safe to tow with, fun to drive every day and a class leading competitor. If you think street-able, clean, stealthy power is cool, then this is the turbo for you. Duramax Tuner's custom-built Mach 2 (67mm) compressor wheel is specifically designed to maximize peak power while maintaining a wide, useable powerband. To fit the monster compressor wheel, they developed a unique, OEM appearing, anti-surge ring, which nestles in the factory compressor cover. Matching the class-leading compressor performance meant updating the center section which is fitted with a 360-degree thrust bearing to increase reliability under heavy load transitions. The wastegate was even updated to make sure you have the most amount of power and the quickest spool-up. With the compressor side and center section put together, a turbine wheel and exhaust housing upgrades had to be made. The LB7 Stealth Mach 2 (67) features the largest turbine available in an IHI-style (stock LB7 turbo) frame. This dramatically reduces drive pressure and allows for serious power production even at high RPM where the IHI typically falters. This monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure, which not only helps make more power but also manages EGT's (Exhaust Gas Temperature) under heavy load.
