This has been done, and there are many write ups on the internet. It's extremely expensive, and not easy.

Honestly, if this is how you start such a monumental task, it's unlikely to be something you'd actually do.

One of the most talked about, but rarely done swaps when it comes to TJs. Weight alone would end any thought about it for me.

See above...almost 800 lbs hanging off the front is just too much for a short wheelbase TJ...especially over OEM axles..

That's cool. You should definitely do some challenging work on it. That's the only way to learn. Get it running as it is, and then make some mods as you go. Keep it simple at first.

It's just that the Cummins swap is very expensive, very hard, and of debatable value. There are so many peripheral things to consider. It's not a good way to start with your first vehicle.

There's a lot of things you can do to a 20 year old TJ that will teach you a lot about vehicles and working on them.
Maintenance, replacing bushings/bearings, frame cleaning/painting...
If you really want a 4BT TJ, you've got a lot of research to do, and you're probably looking at $10k.
In the mean while, if you're going to make your TJ into one, there's a ton of other things you could do first, with a diesel Wrangler being the ultimate goal.
Most questions have been asked already, don't let that stop you from asking one, but you already have access to a ton of info without waiting for replies.

I would Imagine a lot less considering it's a car, Google JF for it because it's been done.
Personally,any way you look at it this endevor is going to cost a lot of money.
