  1. Good morning to all! I was curious as to which transmissions will bolt up to the Jeep 4.0. Right now I believe there is a Chevy trans connected to the vortex swap the previous owner did (haven’t ripped into my MJ for a swap yet). Appreciate the help this far guys! Love the website also quick side note I was told I need to do 10 replies or posts and I was just curious if someone who is a long time user of this forum could clarify that for me
  2. Hey Guys! The cold here in Philadelphia has delayed my work on my 88 Comanche project, 4.0 5speed. I got the slave cylinder put in and the transmission back in about 2 months back and figured why not try to start her up. I bought the truck not running and it hadn't run in 3 years. Well not surprising, didn't start. Cleaned all the ground, and electrical contacts. No dice. Everything having to do with ignition looked brand new, obviously someone had tried to start her before. What the missed? Crank position sensor. Put a new one in and tried to start her up. She lives again!!! Cranked up on 3rd try. She is running rough and over revved to 3000rpm but i am not all surprised. Its been a while since anybody loved her. Probably will need a new IAC. Any other thoughts on the high rpm? My next task is to fix the throttle body. The spring does not release. if i hit the gas it will stay in position. Tried soaking with pb blaster, didn't seem to help. My question is should I rebuild it? How do I rebuild it? does anyone know where to buy a new one. Only ones I have found thus far are not Renix compatible. I would almost rather replace than rebuild but if i cannot find one, that is not an option. Any input would be much appreciated. Thanks in Advance, Ant
  3. Recently purchased an 88 MJ Pioneer w 315k. Body is sweet, very unique color. My bud owns a Shell station and far handier than I on big stuff. Want to swap motor for junkyard 4.0 w less miles. What should i be budgeting for this? Really have no idea.
  4. I'm getting ready to retire the 2.8 liter so called engine to a 3.4 and while doing my research some forums say to turn down your flywheel and neutral balance it or there's say to get a 88 or newer already neutral balanced flywheel. Anyone tried either one????
  5. So my engine just quit on me. Anyone know a good place to buy a re manufactured one for a 1989 4cylinder??
  6. My name is Eli and I am 15. I bought my first 1987 Comanche base a few months ago. It have a 2.5 4 cyl. engine and 4 speed manual trans. I have already fixed the exhaust on it and changed out the headliner. I really enjoy this truck it is fun to drive and I'm wanting to do a few things to it. I'm wanting to put in a straight 6 engine with a 5 speed manual trans. Replace the dash board/ dash pad with a new one because the one it has now has a huge slit in it. Give it a new paint job, and customize my one light bar/sports rack to put KC lights in the back while still having a box in the bed. These are just a few of the major things I want to do to my truck. If any of you more experienced people out there that can give me a few tips or tricks about this stuff that would be GREATLY appreciated.
  7. Hi guys havent been on here in a while but its summer now and work on the truck begins once more. So ever since I have had the truck it has run rough. It has gotten rougher and rougher over the years. Its at the point where it won't start without some gas and then it won't remain at idle without gas. After it has warmed up itll idle okay, but still pretty rough.' So i took it to a basic auto shop to check it out. They found that one of the cylinders compressions is at around 25lbs which is what they said was low comparable to what they said it should be like all the other 3 is 150lbs. So its been practically running on 3 cylinders. I presume it will eventually just get worse. Do you think it would be worth the rebuild of the engine? My comanche is stock I use it for travel at school. I have one year left of school and I am hoping to have this running for a couple more years while I get my first job and settle down without worrying about a new car payment just yet. I have done routine maintenance on this thing, and have done a lot of work on it. Put a whole new exhaust on it. I put in a new radiator, water pump, and numerous other things. It doesnt have A/c nor power steering so there will never be those kind of problems. Its pretty basic and I'm thinking the rebuild of the engine really would nothing else to break, hopefully. What would be the estimated price to go take this engine to be rebuilt? and after the rebuild how much would you expect it to still run for? Thank you in advance for your help!

  12. Good morning everyone. So I am new to the Comanche club however I have been following the forums for quite some time now. I came by two comanches very cheap however 1 has a damaged frame and the other one has a blown 2.5 so I will be swapping the 4.0 and driveling into the 2.5. Now the trucks are as follows. 1988 swb comanche with 2.5l 2wd dana 35.not sure what transmission havent checked. 4 speed stick. Aside from engine truck is in great shape. 1989 (11 month) lwb comanche with 4.0l ax15 np231 and a dana 35 out back dana 30 front. This truck is in really bad shape frame and body wise. Now I am no stranger to engine swaps just a couple comanche specific questions. Being both renix do I need to change all engine bay wiring and if so will I run into c101/c100 issues. If I do run into issues there will I need to swap cab wiring as well? Will I need to change fuel pump/sending unit? If so will both tanks be the same lwb/swb. Lastly are there any comanche related engine swap issues I should look out for that I might not now about. Thanks for your time all and I look forward to your expert advice.
  13. Hi everybody!!! I'm new here and just thought I'd ask a question. I've searched everywhere but I cannot find a build log of someone putting a diesel Renault into a non diesel Comanche :???: I've been around the jeep scene for awhile now and I know people put a 4bt in them but nothing else :hmm: I searched this AWESOME forum and google but I found nothing. I imagine it would be easier just to find a diesel one but I've searched all north america and nothing (I'm Canadian eh). Just want you opinions on this topic. I know a few people on here have a diesel, hoping they will pop in to say hi :thumbsup: . :MJ 1: .
  14. I'm doing a 1.8l Isuzu diesel to my 89 mj and I wanted to know if anyone Knew ware to get an adapter plate made/bought so it bolts to my transmission
