Funny, I was just looking for reasons to drain my bank account and came up with these: (* I know, one of these is for a 93 wrangler. Gotta take what you can get sometimes)

When I first bought my CJ-7 back in 94. The PO had installed a 4cyl Isuzu turbo diesel. It ran great till the turbo went out. It would get 30 mpg hwy running 70. It came with 4.11 to 1 gears and 31" tires. Being young and dumb I took it out and installed a sbc 283, then a sbc 400, which it still has. Now though with 33" tires and the same 4.11 gears it now gets prob 8 mpg. Although it has plenty of power to come out of a mudhole.

I sure wish I still had that little diesel though.

This is an old post. Im partial now to the 4bt. Dont bother trying to buy one. Big$$$$$, but you can usually find the whe truck witha good motor in it for 700$ or less. Being a cummins motor, tranny options are abundant, nv4500, few automatics from dodge, sm465, and so on. I guess a 4bt swap would run close to the same price as putting in a 5.0, or any other efi motor. Also, i would guess easier too, no ecm to worry aboht, no ignition system, plus a lot of other stuff that u need to run a gas motor. 4bt has what, 4 wires goung to it.

The only reason i know any of this nowadays is my hauler is a 1997 dodge 2500 cummins. Learn alot when u own one.

1988 Wrangler 89000 miles, no rust, no rot, all nice and pretty.. Runs down the highway really nice too.. This is great fun.

Tishomingo comes up as in Oklahoma. It's Paladin trucks. Company's posting: Product Detail It's weird that they didn't say who they were in the CL ad.

I'm all for more J54 owners, I love mine. Got it off eBay from a fellow in Oregon. Get's 30 mpg and with lockable hubs plus overdrive that'd be more like 38 or 39 mpg. CJ3B clone. Transfer case is Dana Spicer 18 clone. Transmission is either a T90 with an additional intermediate gear or a T98 with no granny gear.

But that's off topic from the engine question. Engine is the Mitsubishi 4DR5, used in the US in Mitsubishi forklifts: 2.7L 4 cyl. Variants were used in the Mighty Max pickup. A Mitsubishi Diesel Jeep is a great option if you don't want to pay the $12000+ labor (Jeff Daniels quote) to swap a 4BT into a CJ. You won't have many options to select from unless you import it yourself. Luckily there weren't many factory options, so they're all about the same anyways, just condition.

If you're swapping a diesel into a Jeep stick with the tried and true 4BT. There's tons of info online about solving the custom things you'll have to deal with.

Just realized that I wrote all this and it's an old thread. Oh well...

About California: Recently looking at a thread about Diesels in CA and the issue of which diesels can be put in a jeep because of vehicle type etc. For instance the 4bt is not for a passenger car or 1/2 ton truck. This is why people can swap in a 1.9 TDI and others. So what I was thinking... has anyone put the 3.0L diesel from the BMWs? I have one in my X5 and it's a great engine and would love to have it in my CJ. I'm sure there would be tons of issues with the computer not to mention the tranny. Just a thought.

3500 cj7 are sold by Renault in France: 500 with gazoline engine and 3000 with diesel engine; a lot was swapped with a turbo diesel engine with
88 HP and 20 mkg, the same engine has equiped the cherokee
the parts are perhaps available also in USA

If you're going to adapt a German engine, do the OM617 motor out of the older Mercedes.
It's the cast iron "million mile" engine. There's a ton of them out there, and generally, in
the rust belt, the bodies go long before the motor. Pick one up for $500-$1000 if you get
lucky...
