2004.5-2007 5.9L Cummins S400 High Mount 2nd Gen Swap Kit

Bolt an S400 into a third-gen 5.9L

This kit has the parts needed to run an S400-based turbo on a 2004.5-2007 5.9L Cummins using a second-gen style exhaust manifold (manifold and turbo sold separately).

Wehrli mounts the manifold pointing up, which keeps the downpipe simple: the short 4 in. downpipe meets the V-band on the factory exhaust pipe just like the stock turbo elbow did, so no cutting is needed.

Who it's for

5.9L Cummins owners moving to an S400 single with a 2nd-gen-style manifold.

Fitment notes

• Fits 2004.5-2007 Dodge/Ram 2500 and 3500 with the 5.9L Cummins. Wehrli says it also fits 2003-2004 trucks updated to the 2004.5-and-later downpipe / front pipe.
• Will not work with turbos that use a race-style compressor cover.
• Not compatible with Banks intercoolers; contact us if your truck has one.
• If the turbo and manifold are not bought with the kit, the brands must be given at order, and some may need to be sent in for the kit to be built.
