This kit will allow you to install an S400 based Turbo on your 2010-2012 6.7 Cummins with an ATS or Steed Speed 2nd Gen Style Exhaust Manifold (Sold Separate). Kit includes all components needed to install turbo. We mount the manifold pointing up which allows for a quick and simple down pipe install- no cutting of your exhaust system required! Our down pipe connects to the v-band flange on the exhaust system front pipe just as your factory turbo/cast elbow did. NO Bending of AC lines is required with this kit! Stainless steel oil feed (#6) and oil drain (#10) lines. OEM Coolant tank can be used, we do offer a fabricated aluminum tank as an option separate. 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. All tubing is TIG welded and mating flanges are CNC machined with O-ring seals where necessary for a boost-leak free setup. If you are not purchasing the turbo and manifold from us you must specify the brand of manifold you are using, and you may be required to send the turbo and manifold in to us for the kit to be built.

The parts look great with perfect powder coating, no errors or flaws at all. Everything went smooth on the install (did it all myself with no help except for removing the old manifold/turbo) from the manifold, downpipe, turbo, oil lines, hot side intercooler pipe. Only lost maybe 2-1/2 gallons of antifreeze. Truck hasn't been retuned yet but it runs so good and sounds like nothing else.
