a 4bt into a mj has been done. although i think it would be easier to do it to a tj or yj as they have frames instead of unibody

there is another option that has not been mentioned yet. its a 6at. basically a small cummins 6 cyl diesel. came in some of the bread vans. if i remember right its about a 3.2l and a bit lighter then the 4bt.

the 4bt can be commonly found in the big box vans use by bread company's. and they pop up on craigs list every once in a while.

do you guys have more on the Isuzu diesel? that seems to be more of a better potion.

has anyone tried a duramax swap? i know it being a 6.6l it may be too big for the bay to hold. idk just a thought

Anyone ever tried to use one of the Toyota engines?  The 2H engine put in the 80's FJ cruiser would put out 177 ft lbs of torque (4.0L).  Or more interesting, using a 4.5L V8 1VD turbo diesel from the Land Cruiser 200 series...  My dad has a 100 series land cruiser with the 4.2 L I6 1HD turbo diesel engine, which would be also another good choice.  Or maybe the one 3.0L Turbo Diesel engine that comes in the Hi Lux and the 4Runner in overseas markets...

I believe there is a 22rh or something like that in a cherokee on NAXJA, something like 85hp/95tq and it gets 35mpg, just BARELY drivable on the freeway though, haha. I would imagine a turbo'd oiler would be MUCH better. Still, closest and best thing I've seen is the CRD swap into the Comanche. The same guy recently acquired a whole, totalled, CRD KJ, and plans to use it for a later model cherokee. I swear he has four or five projects coming along!

This thread needs a wakeup.

The turbo Deisel Registry has a lot of cool projects.

I've been looking at a small turbodeisel that Kohler builds. Sweet little unit and the weight is doable.

No way it will go through  a smog test its a offroad motor but if you can dodge the bullet it would be coool .

In CA, Diesels aren't smogged.  Although the DMV might send you to a referee station to get it checked.  It's a gray area where if the DMV says OK, you're golden.  If not then you'll probably get caught at the referee station.

Just on a side note,,, I noticed folks worried about the power levels of a couple engines.

The original Cummins dodge trucks only had like 160 HP stock, no inter-cooler and a small turbo.

Our pulled a 14K lb trailer just fine... I think 135 Diesel HP is pretty good for a YJ... :)

Well, with diesels, you're not looking at HP but rather torque.  The 4BT non-intercooled makes 105hp but 265lbs-ft which is huge.  The power-band is really narrow so it's like you have all torque all the time.

It would be so cool to have a 25 gal tank and gt 30 in a YJ.
I could actually drive past a gas station...

there is a company that makes aluminum 26 gallon tanks for YJ and TJ i believe, saw that somewhere but they were pricey - the way they did it is to remove the cross-frame brace in front of the tank.

[dwtaylorpdx]

I just re-read my post,,, :)

I should have said get 30 MPG! (Small diesel)

Yea I've seen the AL tanks Pretty Shiny (Pretty pricey  )

i was "admiring" my stock gastank today - with the 1'' body lift i have i could probalby fit another 4 or 5 gallons if i would have an aluminum one that is 1'' taller - too bad you can't extend the stock one

Here are some other engine swap ideas.  VW 1.6L TD and a 1.9L TD.
