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.
The optional Driver Side Transmission Dipstick Tube makes installation of the down pipe easier.
