Description

The Industrial Injection S471 Turbo Swap Kit converts the 2003-2007 5.9L Common Rail Cummins to a 2nd-gen-style single S471 setup, configured here with a tight .90 A/R turbine for hard-pulling, drivable-track power. It's the kit for builders who want all-out performance but still need the truck to come up on boost off the line.

The package ships as a complete bolt-on swap — turbo, custom S&B-designed intake, mounting hardware, gaskets, and clamps.
