Geonovast Posted April 9, 2010 Share Posted April 9, 2010 4.0 would be your easiest option, and it keeps it Jeep. Link to comment Share on other sites More sharing options...
91_2.5_2wd Posted April 9, 2010 Author Share Posted April 9, 2010 I was thinking that, but a 318 would keep it chrysler.. Link to comment Share on other sites More sharing options...
Geonovast Posted April 9, 2010 Share Posted April 9, 2010 Eh.. But remember your MJ was designed to house a 4.0. Several people on here have small blocks in their trucks, and it takes heavy modification, and I believe all of them have cooling issues. Easiest swap would be to find yourself a busted up 91-95 XJ with a good drivetrain and wiring, grab the whole truck, and swap it over. Link to comment Share on other sites More sharing options...
91_2.5_2wd Posted April 9, 2010 Author Share Posted April 9, 2010 Is the wiring hard? or is it all like hook up and go lol Link to comment Share on other sites More sharing options...
wyk Posted April 9, 2010 Share Posted April 9, 2010 Engine swap? 4.0? or a small block. Keep the 2.5, add 4:10 or 4:56 gears to the rear axle since it's a 2WD. You'll notice a huge difference, and similar mileage unless you travel much at high speeds. Link to comment Share on other sites More sharing options...
Geonovast Posted April 9, 2010 Share Posted April 9, 2010 You will need to swap over all the wiring from the 4.0 donor. Along with all the accessories, cooling system, etc. There are multiple 2.5 to 4.0 swap threads on here, you should be able to dig up pretty thorough instructions on how to get it done. Chances are pretty good you can get yourself a 4wd swap while you're at it. Link to comment Share on other sites More sharing options...

Geonovast Posted April 9, 2010 Share Posted April 9, 2010 I think i need to find someone to help me lol This isn't something to be done by a total amateur(unless you really, really want to) :brows: . It's a lot of work, and a lot of things could go wrong. I'm assuming your MJ is not your primary vehicle? If you tackle something like this, you should take your time with it, and make sure everything's done properly. I'm certainly not telling you not to do the swap, just heavily suggesting reading up on as many 4.0 swaps as you can. If you've got friends that can help, the more the merrier :thumbsup: We'll certainly be here to help you through the entire process, multiple members have done this exact swap.

Geonovast Posted April 9, 2010 Share Posted April 9, 2010 I suppose someone's gotta ask.. What transmission do you have? 4 speed? 5 speed? Auto? Link to comment Share on other sites More sharing options...
91_2.5_2wd Posted April 9, 2010 Author Share Posted April 9, 2010 Okay, I'm buying an 86, not sure what tanny is. but I'm swappin that one and drivin my 91 Link to comment Share on other sites More sharing options...
Geonovast Posted April 9, 2010 Share Posted April 9, 2010 Okay, I'm buying an 86, not sure what tanny is. but I'm swappin that one and drivin my 91 That information would have been good to have at the start of this thread. Given your lack of a signature, we all assumed you wanted to swap into your 91 with a 2.5, which we only knew you had because of your screen name. 86 could be a completely different animal when it comes to swappage. I suggest you get a signature with more details of your vehicles, (year/engine/trans/4wd or not/bed length). It will help further tech questions. Also be a tad more specific when asking your questions. Please? 8) Link to comment Share on other sites More sharing options...
91_2.5_2wd Posted April 9, 2010 Author Share Posted April 9, 2010 bahaha, sorry dude, okay. it's an 86 2.8(6cyl) and i want to put a 4.0 and maybe 4x4 swap. does that help? Link to comment Share on other sites More sharing options...
Geonovast Posted April 9, 2010 Share Posted April 9, 2010 If you're looking for a (fairly) quick and easy swap for the 2.hate, you can track down a GM 3.4L V6. It's the same block as the 2.8, it's still a V6, and in the realm of motor swaps, it's among the easiest. Plenty of 2.8 -> 3.4 swap threads around here too. :thumbsup: Link to comment Share on other sites More sharing options...
