Diesel Conversion

I have a 02 with the 4.0 liter inline 6 with a manual transmission, and I want to convert over to a diesel engine. Has anyone done this conversion on theirs if so what did you use and how much modding was involved?

Years ago, Jeep offered a Perkins Diesel as an option and today I saw a photo here of a Cummins 5.9 in one, so it is of course doable. My experience with 4X4 Cummins powered trucks is they are front end heavy. One of the advantages of a Wrangler is their light weight. Good luck with your diesel conversion.

I've heard that the 4bt is a good engine to put under the hood. Google "diesel conversion jeep" and you'll get plenty of ideas
