Twin Turbo Kit for Duramax Hummer

This Kit is for SERIOUS Performance. It includes everything that comes in our standard Duramax conversion kit, plus all of the components to install an S400 frame Turbocharger in series with your factory or modified VGT turbo on 2004.5-2010 Duramax Engines. Capable of supporting over 1000hp and 80+ psi of boost pressure…this system has no equal. These components have been tested for many years of offroad racing and durability testing on Tow rigs and drag trucks. Nearly 10 years of real world durability testing has been performed on all of these components with no failures and incredible performance results.

You must use our specific Stainless Steel Turbine Housing to work with this system and we can provide the complete Turbo charger as well. S400 frame turbos from 72mm all the way to 85mm can be utilized with this kit.
