Description

This kit will allow you to install an S300-based Turbo on your LB7 Duramax. Replacing all 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.
If you are not purchasing the turbo from us, you must specify the brand you are using. Some turbos you may be required to ship to use for mock-up to build the kit.

Includes Driver Side Transmission Dipstick Tube, making installing the down pipe easier.

***NOTE: Our downpipe is an HX40 style flange connection at the turbo, as this style offers the best seal, alignment, and easiest install. If you are not purchasing the turbo from us you will need to make sure your exhaust housing is machined to HX40 style outlet flange! Note the picture above for the HX40 flange vs the full marmon standard style.

The OEM turbo coolant feed port on the upper radiator pipe from the thermostat housing will interfere with the larger WCFAB Turbo Intake in this Kit. You MUST use a WCFAB Billet forward-facing thermostat housing Kit WCF100405 or our Modified OEM Pipe WCF100797. Billet Coolant Port Block Off Plugs DO NOT allow enough room for clearance on LB7 Models.

Product Notes

-We recommend kits to be installed by a qualified diesel performance shop or mechanic.
-Certain upgrades are necessary for optimum performance and drivability. (I.E- Tuning and Lift Pump)
-Must specify brand of Intercooler upon ordering. The Cold side intercooler pipe is built differently depending on brand used.
***NOTE: Our down pipe is HX40 style flange connection. If you are not purchasing the turbo from us you will need to make sure your exhaust housing is machined to HX40 style outlet flange!
