Wehrli 04.5-07 Dodge 5.9L Cummins S400 Turbo 2nd Gen Swap Kit (No Turbo/Manifold) - Bengal Red

If you're looking to upgrade your 2003-2007 Dodge 5.9L Cummins with an S400-based turbocharger, this kit from Wehrli Custom Fabrication is built to make that happen. It's designed to mount an S400 turbo using a 2nd Gen style exhaust manifold, which you'll need to source separately. The kit is hand-built by experienced fabricators, with all tubing TIG welded and CNC machined flanges featuring O-ring seals to ensure a boost-leak-free connection. This attention to detail means a solid, reliable setup for your truck.

What sets this kit apart is how it mounts the manifold pointing upwards. This design simplifies the downpipe installation significantly, allowing for a quick connection to your exhaust system's factory V-band flange, just like your original turbo setup. You won't need to cut your exhaust to get this installed. The kit includes a 4-inch shorty downpipe, a one-piece 3-inch hot-side intercooler pipe, and all the necessary oil feed and drain lines. It also comes with silicone boots and stainless steel T-bolt clamps for secure connections, a dry air filter with an Outerwear's pre-filter cover, and a 5-inch intake. The durable Bengal Red powder coat finish not only looks sharp but adds a layer of protection.

This kit is made in the USA and test-fit on an engine before shipping to guarantee proper fitment. While the turbo and manifold are not included, this kit provides all the other essential components to integrate a larger S400 turbo into your 5.9L Cummins. Please note that this kit is not CARB approved and cannot be shipped to California.
