Product description

Compound Turbo Kits (also known as Twin Turbo Kits) for the 2001-2004 LB7 Duramax have become one of the most popular upgrades for daily drivers and towing rigs. Compounding over your factory turbo charger has been proven to provide cooler EGT's and increased power across the rpm range, all while allowing the use and function of the factory turbine brake feature. They are a great all around setup for towing, the weekend warrior, and truck pulling competition, or racing. With proper tuning (Required) and additional supporting modifications the Compound Turbo Kit can provide up to 650 HP and 1300 LBS of torque.

One of the nicest features of compounding over your factory turbocharger is that the truck will not have any additional turbo lag or loss of spool up, which is common with a larger single turbo upgrade. The truck will have instant response and boost just as it does with only the factory turbo, but more efficient across a wider range, with cooler EGT?s! Every WCFab Turbo kit is hand build in house by our experienced fabricators and welders. Every component is built and test fit on our jigs to ensure proper fitment. All tubing is TIG welded and the mating flanges are CNC machined with O-ring seals where necessary for a boost-leak free setup. We stand behind our fabricated components and workmanship for the life that you own the product. The Compound Turbo Kit comes with all the necessary components to install, with several upgrades and turbo options available. Powder coating is included in the price. Certain upgrades are necessary for optimum performance and drivability. (I.E- Tuning and FASS Lift Pump)
