Maybe the diesel forum would be better for this question, let me know and I'll repost it there.

I just got a '04 3.7L KJ over the summer. Now let's say somewhere down the road I decide I want to switch to a diesel KJ (we're talking years down the road). Would I be able to turn my KJ in a diesel? And what do you think I'd have to do besides the obvious drop in a new engine and HD coils? Is this even a realistic idea or should I just prepare myself for the day I have to part with my first KJ and go buy an old diesel one when the time comes? Thanks guys.

Cheers
PJ

you'd probably need to swap the tranny and t-case also. Probably easier, and maybe even cheaper, to just trade for a CRD.

If you had a donor CRD sitting onsite it would be nothing more than parts swapping, engine, tranny, Bunches of electronic goodies....wiring etc. Even the front crossmember is different so that means front diff, CV shafts. If u lived closer to Mr. Sir Sam he could help u along.

and not to forget replace all the metal gas fuel stuff with cheep plastic, as well as the fuel tank/lines, and hey the one part you could re-use would be your airbox!

there is a site out their showing a crd being put into a Wangler

Ill have to agree, Sir Sam would be the best source of info for doing something like that

Perhaps, but then again when that days comes if I am still(ugh) searching for a good donor for whatever vehicle I wish to CRD swap I may not be too friendly to someone potientially competeing for my same donor vehicle.

Get back its mine, grrrr.


Another thing to consider is all the red tape you face in doing a gas>diesel conversion, depending on where you live that can be excessively annoying, and sometimes impossible. So what it comes down to is that there is a vehicle that is a year newer, hasn't been frakenjeeped together. And you can buy all for a matter of $ and time to find the one you want.

IMO engine swaps are only worthwhile when its for something you cant otherwise purchase, IE CRD TJ/JK.
