***This kit must be used in conjunction with Wagler street cast intake and twisted pedestal.
***Custom High Pressure lines are necessary for proper fitment with the street cast intake on all model years.
***2001-2010 Model years require the use of a van style thermostat housing and upper radiator hose for clearance to the street cast intake.

This kit will allow you to install an S300 based Turbo on your Duramax using a Wagler Competition Street Cast intake Manifold and Twisted Pedestal (Sold Separate) Replacing all of the OEM plumbing 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. 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. It is recommended to upgrade to the V-band outlet on the turbo cover. 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.
