From our seamless integration at the selector valve to the billet adapter we use to tie into the factory rear feed lines, this kit is second to none. You will not have to remove the OEM turbo to install this kit!

Installation Instructions:

  • You will be provided the most up-to-date instructions when you request your quote directly to your e-mail.
  • IF you decide to install fittings into the heads, be EXTREMELY careful when installing the NPT fittings. They are to be installed as tight as you can by hand and then ONLY tightened 1.5-3 more turns. I would HIGHLY recommend making sure the ports are clean and free of debris. Marty’s diesel is NOT responsible in any way shape or form if you crack the head from improper installation.
