The Wehrli Custom Fab S400 single turbo install kit is a complete bolt-on package for 2001–2004 Duramax LB7 6.6L engines, built to convert the stock IHI-style turbo to a larger BorgWarner S400–style set up. The kit upgrades intake and charge plumbing with 5" intake, 3" mandrel-bent intercooler piping, high-flow y-bridge, ceramic-coated downpipe, stainless oil lines and hardware to simplify a big-turbo swap.
