I have a 92 jeep cherokee laredo (4.0)
I want to put a diesel in it (please don't ask why )
I need to know what diesel engine would be easiest to swap with and all the other things I would have to do
Thank you in advance to your replies
Much appreciated

 

Cummins 4bt. Pretty stright foward. I belive there is an adapter fir the aw4/ ax15 transmission.

 

if you have to ask, you probably aren't cut out to do the swap.

the 4bt is a tall engine, I'm pretty sure you would have to go through the hood or lose some up travel in the suspension to clear the oil pan.

 

At cheap. You can't learn if you don't start somewhere

 

Has anyone actually done this after posting this question....

Look up xj Mercedes diesel swap.
Or you can see about a 4bt with an adapter to a Chevy Trans/tcase.

 

Look on google or pirate 4x4 they would have most info youll need

 

there is also a guy who just joined this forum who did a VW diesel swap

 

Ill try and post a pic when I'm finished (though it will take some time). Y'all don't think the CRB diesels out of the liberties would be an easy fit?

 

Why?

 

My friend DDs his TJ with a ax15 and 4bt. Everything down to the a/c and stock gauges work, everyone sells adapters and wiring is easy. Gets 22mpg commuting and 28-29 on the highway with 3.73s and 33s.

Have fun.

 

some cherokees came diesel find out what motor that was.. and you should be good

 

Those motori diesels suck.

 

I saw some j8s renault diesels and a lot of people had good things to say about them

 

the Renault diesels are sluggish, under powered and leak oil almost as fast as you can add it in......

 

Not that practical:
- VM Motori 2.8L: Found in Euro Jeeps across the pond aren't that great and parts here for them blow.
- Liberty etc CRD: Amazingly expensive
- VW TDI: Lots of work, looks nice when done properly, but really lots of work especially if you have an electronic one

Practical:
- Cummins 4BT: very popular engine and easy to source the unit and parts. Mechanical diesel injection so no computer to move over. Pretty tall so I think 3" or 4" lift is a minimum.

- Mercedes OM617: 5 cyl with similar numbers to the 4.0, mechnical injection, easyish to find, pretty much bolts up with an adapter plate to the AX-15 (great resource: http://www.mercedesdiesel4x4.com/)

Don't forget you'll also need to look at regearing, the exhaust system, and fooling your ECU to stop whining & made the tach work if you're going to do it right.
