Housekeeping first:
Vehicle: 87 shortbed MJ 2wd, 2.5L throttlebody FI, 4 speed manual (AX4?).
Drivetrain I'm think about swapping in: '90 4.0L, 5 speed manual (AX5?), NP 231 t-case.
Basically, what I want to know is what do I need to watch out for because I've done my fair share of wrenching but never an engine swap. This thread is also supposed to help me decide whether or not to buy this drivetrain.
-I assume I'll need the computer with the engine and all the sensors.
-Will a 6 cylinder bolt in or does the body need to be modified?
-Will the transfer case bold on to the current cross member or will that have to be replaced or modified?
-Obviously I'll need a new driveshaft do to longer drivetrain, hopefully I can find one at a JY.
I did a google search, and search but didn't come up with anything even though I'm sure this has been covered a hundred times. So, feel free to point me to a relevant thread. Any help is appreciated.
