Product Details

Product Name: WC Fab S400 Single Turbo Install Kit, for 2001-2004 Duramax LB7
Manufacturer: WC Fab
Thoroughbred Diesel Part #: WCF100489
Fitment Notes: 2001-2004 GM Duramax LB7

This kit will allow you to install an S400 based Turbo on your 2001-2004 LB7 Duramax. Replacing all of the OEM plumbing and y-bridge with high flow 3" diameter piping. Oil Lines are high quality stainless steel braided Parker Lines with the oil feed line routing from the main oil galley on the side of the engine block. We designed our down pipe to connect with your exhaust system V-Band and clamp which simplifies installation and does not require you to cut your exhaust system. You can upgrade to the 3 1/2" down pipe but this will require cutting of the exhaust system to install. If you are not purchasing the turbo from us you must specify the brand of turbo you are using, some Turbo's you may be required to ship to use for mock up to build the kit. Each turbo kit is hand built in house by our experienced fabricators and welders. Every part is built and test fit on an engine to ensure proper fitment.
Includes Driver Side Transmission Dipstick Tube which makes installation of the down pipe easier.

Turbo Down pipe is designed for Half Marmon style S400 exhaust outlet; 4.6" Diameter flat flange. NOT compatible with HX40 style exhaust outlet flanges.

NOTE: Race cover style or SXE turbo chargers will require the use of a forward facing VAN style thermostat housing and hose, sold separate.

Note:

  • Anything powder coated will have a lead time of 15-25 days.
  • Non powder coated products will have a 2-3 day lead time.

Reviews

  • Will this fit a 07.5 Lmm? It says in the orginal listing it would fit 01-16 Trucks but only allows me to select 01-04 model truck but the piping looks identical? I just want to verify this will work with my truck before purchasing
