This kit is for a twin turbo set-up, S400 over your stock turbo. It is a compound turbo kit for the 2003-2007 5.9L Cummins, designed for daily drivers, work trucks, and tow rigs seeking increased horsepower, better fuel mileage, and superior EGT control with stock-like turbo spool characteristics. It is capable of up to 1000 RWHP depending on turbo and fuel system modifications. One of the key features is that it retains the drivability of the stock turbocharger with no additional turbo lag. Each kit is hand-built in-house by experienced fabricators and welders, with all components built and test-fit on jigs to ensure proper fitment. All tubing is TIG welded and mating flanges are CNC machined with O-ring seals for a boost-leak free setup. The kit comes with all necessary components for installation.
