Diesel XJ?

Anyone ever thought about making their XJ into a diesel? Ive got a buddy thats a diesel mechanic who said he would help me if i wanted to diesel the XJ. I was seriously thinkin about puttin a chevy duramax diesel in there they produce amazing power and are apparently no bigger than any Chevy 350. By next spring hopefully the XJ is gonna be trail rig only so its not gonna matter how much work has to go into a project. I would love to run diesel in my XJ it would definitely be different at least around here.

That would be a sweet setup for a trail rig. Torque torque and more torque.

How much does one of those suckers weigh? Bolt up a strong manual trans and TC and with the fabbing it will take to get that sucker in, long arms would be a nice add on as well.

the link shows a diesel swap into a grand cherokee, its not a chevy duramax diesel motor but its a diesel conversion so it might give you some kind of idea

If you put in a full sized diesel engine (5.9), I expect your front bumper would be dragging on the ground. Also youd have to upgrade your entire powertrain as you'd be breaking things left and right.

If I did a diesel swap it would probably be with the new 3.7 Liberty Diesel, Jeep in Jeep, thats how I want it

Might want to wait a few years for the price of junkyard libertys to come down, I expect a junkyard would get a pretty polly for any libby diesel or no. I have heard of using a diesel of a mercedes benz car, thats keeping it in the same family as jeep isnt it?

836lbs for the engine weight, would that really make it noticeably sag?

Im sure thats significantly more than a 4.0. You have to figure in a new transmission and transfer case as well. Maybe someone can chime in on the weight of a 4.0/AW4/232. I have heard complaints of saggage with a bumper winch combo.
Also you might have clearance issues with the front axle and the oil pan of the diesel which holds about 50 gallons of oil.

One additional note is that you will need to reinforce the unibody frame to handle the torque of a big diesel. Over on another site there was a guy that used a 5 cylinder mercedes diesel I think it was possibly on NAXJA.
