hello there, i'm Patrick, i just bought a 1985 full size Jeep Grand Wagoneer
my question is i want to possibly convert it over to diesel if i could possibly
do it what could i use, cummins,Power Stroke with turbo,or Gm diesel 6.2
6.5 or the Duramax which one could i use and does each engine have it's
own setup, can somebody please help me with this project.
Hi Bug
There have been a couple of Jeeps done with a 6.5 that have been members here.
You can use any of the motors you listed,just depends on your mechanical ability.The easist will be the 6.2 or 6.5 with a mechanical injection pump.The cummins will be harder to fit into the engin compartment.The duramax requires computers that will have to be intergrated into the jeeps wiring system.And the power stroke is a little bigger than the 6.2/6.5 and will have a computer to run it as well.
6.2/6.5 parts are cheeper than the rest.I would look for a 93 GM pickup it was the last year with a mechanical pump and had the 6.5 with a turbo.Buy a complete running truck is the best,use what you need and sell the rest for parts and you could get your money back.

The 6.2/6.5 goes in with the same mounts that you would use for a SBC, so you get a set from Novak or Advance and save some fab work.
