Camarozz is correct. If you are not a mechanic or have a lot of experience under your belt, it will be expensive and time consuming. It isn't as easy as everyone says UNLESS YOU HAVE A DONOR JEEP. And if you have that, we wouldn't be "discussing" this right now.
I have put a V6 in my 1992 YJ. It began with a 2.5. I didn't go inline six because I already owned the V6 BUT THE CONVERSION IS ALMOST THE SAME. You can't use your AX5 transmission or your NP231(unless you change input shafts.) If you check out my signature below, you will see my rebuild information and you can check it out. It goes into a lot of detail about what you will need to do for the swap and most of it applies to your swap, as well.
I know it will be some work and my dads been a motorcycle mechanic for 35 years.we actually just did a motor swap on my brothers ranger.we put a 302 on it.I'm just trying to figure out which motor i need
oh, sorry, Transfer Case; referencing that I would use the motor and transfer case from the same donor. Otherwise you might have to change the input shaft of the transfer case depending on what transmission, and transfer case, you end up with.
