Mj Looking to swap to diesel. 1988 Comanche

I want to drop a diesel engine in to my 1988 comanche pioneer. Has anyone done this? Looking for advice as to what engines would be good options and where I can be looking for them.

4bt Cummins is the most popular and plentiful swap. There are several other options that get more complicated and expensive, but are smaller packages. Like Isuzu.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

Why diesel?

Maintain, wheel, upgrade, repeat.

A Toyota "L" series diesel engine will go in your MJ or XJ without major modifications. Those engines came in early 80s Toy pickups sold in the US. The "L" is 2.2liter, the "2L" is 2.4liter. The 2L-T was a turbo variant.

Not a lot of power, but good fuel economy. I put one in my XJ four years ago to save it from the junkyard. After 30,000miles, still doing great.

This is the company I plan to get my adapter kit from when I get around to replacing the 2.5 in mine. I believe they make a kit that will work in your comanche and can shed some light on the process. I spent some time talking with the guys at their booth at Bantam and it's pretty nice work they do, far lighter than a cummins, and you're only changing the engine and keeping pretty much everything else.. and you can burn fryer oil.

my buddy in the club just finished his 89 swap with a 4BT. lots of work and a few changes along the way.....I'm trying to talk him into making a small bio-diesel plant in his backyard so the MJ smells like french fries...hehehe.

Here's a couple pics.

I second this, get a early 80's 300d. inline5 turbo very little work and have plenty of power for a mj. im currently driving the donor car for my next project back and forth to work. easily reaching 80mph+ and im running used 10w hyd oil. sometimes a little diesel mixed in these engines are super tough and inexpensive.

Try to look for what is available as a complete package. Here in Europe diesels are much more common. In my 1981 CJ7 originaly is an Isuzu 2.4 diesel with a T150 and a Dana 20; I set it up again with a complete drivetrain of a Daihatsu fourtrack 2.8td with a manual 5 speed and a limited slip in the rear dif. You can get a complete car here for some 800 euro's (850 dollar). The early XJ Cherokee came with a 2.1 Renault diesel which is underpowered for an xj. Later models came with an VM diesel as also used in Grand Cherokee ZJ. A complete drivetrain would be easier then working with adapters, and probably cheaper. On the other hand; I have problems getting my hands on some nice american parts like a SM465 as you will have finding diesels over there!
For example; find me a nice 1956 GMC suburban, and I will trade you for a dozen XJ diesels

I'm now working on a deal for my donor car...$1000 for a 84 mercedes 300sd, already has a grease kit installed, being daily driven. It even comes with an older parts car that i can scrap to recoup some of the cost. I'll be looking at it next monday, hoping it checks out and I can bring it home next weekend.

Edit- the guy sold it before I could get there. back to searching craigslist.
