Re: Has anyone ever put a diesel in their Jeep??
If you go with a Cummins 4BT 3.9ltr 4 cylinder diesel you have the exact same engine as the 6 cylinder cummins (minus 2 cylinders obviously) and thus you can do alot of the same mods you do to the 6 cylinder to get extra horsepower and torque.
The 4BT is lighter and gets great mileage as said above, and in my opinion you don't need a hot rod engine when rock crawling. In stock form, the 4BT puts out around 105 HP I think. These engines are rated to run up to 500,000 miles so you get longetvity too. These engines come in the Frito Lay delivery trucks and have a Chevy SM465 tranny behind them, so all you would need would be the kit from AA to adapt the 465 to you Dana 300 and your set to go.
I think you can use the NV4500 too, becasue I think the bolt pattern is the same as the 6 cylinder, so get you a 4wd dodge nv4500 and you don't need any adapters.
This is the plan for my scrambler....it would already have it, but I decided to spend the money I had saved on a trailer instead, but I'll get it sonner or later.
Go to <a target="_blank" href=http://www.tdr1.com>www.tdr1.com</a> and go to their discussion forums and the board called cummins conversions, theres alot more info there.
I was at Katemcy last weekend and wanted to get a look at the Diesel Jeep while I was there, but didn't get around to it.
