I have a 98 laredo with the 4.0 in it. I've found a guy with a 97 5.2 that has been wrecked in the rear end that he is selling for 400 bucks. Assuming that the v8 and is in good condition, how hard would it be to swap it into my jeep? What all would I have to do in order for it to work? Everything I've found on here is just people bickering over whether or not to stroke out the 4.0 or swapping in a dodge engine. Thanks
everything needs to be swapped over. motor, trans, wiring, exhaust, etc. alot of work. but if youre hell bent on doing it, it can be done. personally i would just find a good one with a 5.2 already in it.
Reliability is relative
Well, my trans is gettin ready to bite the bullet anyway, my exhaust has leaks, and there are a bunch of other things that could be fixed a lot easier with the engine out. I just figured that if it was as straight forward as, taking old out and putting new in, it would probably be worth it since I'm going to end up doing it one piece at a time anyway. As far as emissions go, I live in rural Kansas where apparently your neighbor can't be gay but you can single handedly ruin the environment and get a high five, so I don't think it will be an issue. I would love to find a good 5.2 but everyone around here is trying to get rich off of craigslist so they aren't cheap and I don't have the money to drive 300 miles in any direction to go look at a vehicle. I haven't bought anything and I have other things to pay for before I could consider buying the wrecked jeep but I'd like to know as much as I can before I spend the money on it.
It's a lot more effort than you think. Remember, it's not going to be just a motor swap. You are going to have to swap out the motor, transmission, exhaust, ECU, TCM, both axles if you want 3.73 gears, motor mounts, transmission mounts, etc. It's better to just find a jeep with a 318 in it already.
