2001-2004 LB7 Duramax Stealth Mach 2 67/71 Drop In Turbo - Blackout Edition

Your truck's future has never been darker...

Introducing the Blackout Edition Mach 2 Stealth Turbocharger for your 2001-2004 6.6L LB7 Duramax from Calibrated Power.

This special edition turbo takes the Stealth 67 Mach 2 you know and love, and gives it a healthy dose of the 'below the radar' look you have come to expect from Duramaxtuner.com. Black anodized billet compressor wheel, black powder coated compressor cover, black high temp ceramic coated exhaust housing and a black anodized billet waste gate canister and bracket. This turbo provides maximum performance with an ultra low key OEM+ look under the hood. They'll never know what hit them when you come flying by.

This custom-built 67mm compressor wheel is specifically designed to maximize peak power while maintaining a wide, usable powerband. To fit the monster compressor wheel Calibrated Power Solutions 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. Even the wastegate has been updated to make sure you have the most amount of power and the quickest spool-up.

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. The monster turbine helps you achieve as close to a 1:1 ratio between drive and boost pressure. This not only helps make more power but also manages EGT's under heavy load.
