Forward Facing Thermostat Required: 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. Billet Coolant Port Block Off Plugs DO NOT allow enough room for clearance on LB7 Models. You MUST use a WCFAB Billet forward-facing thermostat housing Kit WCF100405 together with this kit to complete the installation.; WCFab 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 turbine exhaust housing is machined to HX40 style outlet flange! Note the picture above for the HX40 flange vs the full marmon standard style.
