This complete kit allows for installation of a Borg Warner S400 frame turbocharger in place of the factory VGT on the very capable 2017-2019 L5P Duramax engine platform. Replaces all of the OEM plumbing and y-bridge with a combination of high flow 3" and 3.5” diameter piping and Y-bridge. 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 bolt directly to your exhaust system which simplifies installation and prevents the need for cutting or additional modification. If you are not purchasing a turbocharger from WCFab you must specify the brand and type of charger you are using. Some turbos may be required to be shipped to us for mock-up to build the kit. 

Proven capable of supporting over 1,000 WHP on our shop truck with appropriate supporting modifications. 

NOTE: CUSTOM TUNING IS REQUIRED. This is a Racing Product designed for Competition Use only. 

***Built transmission, injectors, stroker CP3 conversion and lift pump recommended for optimum performance***
