Description

The Wehrli Custom Fab S400 Single Turbo Install Kit is designed to replace the stock IHI style turbo with a Borg Warner S400 style setup on 2001-2004 Chevrolet Silverado and GMC Sierra 2500 HD/3500 trucks with the 6.6L LB7 Duramax diesel engine. It includes a 5" fabricated aluminum intake with a heavy-duty sheet metal air box, a 3" high-flow Y-Bridge & cold side intercooler pipe, and a 3" 2-piece hot side intercooler pipe with a V-Band connection. The kit also features stainless steel braided Parker oil feed and drain lines, a T4 fabricated steel pedestal, a high-temp ceramic coated turbo downpipe, and a driver-side transmission dipstick tube. All piping is 14-gauge mandrel bent aluminum with a custom candy teal powder coat finish. Made in USA.
