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

If you're looking to upgrade the turbo on your 2003-2007 Dodge 5.9L Cummins, this S400 turbo swap kit from Wehrli Custom Fabrication is designed to make that happen. This kit is specifically for installing an S400-based turbocharger when using a 2nd Gen style exhaust manifold, which is sold separately. It's a popular choice for those wanting to improve airflow and performance beyond what the stock turbo can offer.

Wehrli Custom Fab builds these kits by hand, ensuring each component is carefully fabricated and tested on an engine to confirm proper fitment before it ships out. The tubing is TIG welded for strong, clean joints, and the mating flanges are CNC machined. Where needed, these flanges include O-ring seals to create a boost-leak-free connection, which is crucial for maintaining consistent turbo performance. The kit mounts the manifold in a high position, which simplifies the downpipe installation. The included 4-inch downpipe connects directly to your existing exhaust system's V-band clamp, just like the factory setup, meaning you won't need to cut your exhaust to install it.

This kit comes with everything you need to connect the turbocharger itself, including a 4-inch shorty downpipe that mates to your exhaust's V-band, a one-piece 3-inch hot-side intercooler pipe, and the necessary oil feed and drain lines. It also includes silicone boots with stainless steel T-bolt clamps for secure connections. The kit features a durable custom powder coat finish in WCFab Red, a 5-inch intake, a dry air filter, and an Outerwear's pre-filter cover to help keep debris out of your intake. Please note that this kit is not CARB approved and cannot be shipped to California.
