dishdude Posted October 23, 2005 Share Posted October 23, 2005 88 Chevy 2.5 into 87 Comanche. Is this an easy swap? I have the entire Chevy truck in running condition Link to comment Share on other sites More sharing options...
whowey Posted October 23, 2005 Share Posted October 23, 2005 Its not the same motor. The Comanche would have the AMC 2.5l, sharing basically only the displacement with the Chevy motor. Jeep had previously used a Pontiac 2.5l in the CJ series, but the GM 4-cyl never made it into XJ/MJ's. Jeep stopped using the GM 4-cyl in 1984. The 2.8l Chevy V-6 was in the 84-86 XJ's and 86 MJ's, were dropped for the far superior 4.0l Jeep motor beginning in 1987. So the difficulty would start the same place any other 'non-like' kind swap would be. Motor mounts, tranny adapters, fuel delivery, engine control functions would all have to be addressed at the beginning. Getting a good Jeep motor is almost always a better solution, from a simplicity stand point. You may be able to trade the Chevy truck to a salvage yard for a parts XJ. Most of the parts would be a direct swap from the XJ to the MJ. Link to comment Share on other sites More sharing options...
Cooter Posted October 23, 2005 Share Posted October 23, 2005 As swaps go a complete PITA with no payoff. If you want to go through the trouble to put something with a Chevy bellhousing into a Jeep, go for a 4.3 or 350, you'll be better off in the long run. MJs and XJs are so cheap, however, it would be a better idea to buy an MJ with a 4.0 already in it and not worry about science projects. Link to comment Share on other sites More sharing options...
Pete M Posted October 25, 2005 Share Posted October 25, 2005 The easiest swap for a Jeep 2.5L is a 2.5L. Get yourself the newest one you can cause the blocks are pretty much interchangeable but the newer ones are built better. Jeep on! --Pete Link to comment Share on other sites More sharing options...

HatchetMJ Posted October 25, 2005 Share Posted October 25, 2005 I'm changing out a 2.5L in mine to a 4.0L out of a XJ and its a pain in the sack..pull all wiring harness, mounts, I decided to just swap the dash to save some time...and reconnect a few plugs that don't match between the two for lighting and such...its a pain in the @$$.....I hate fuel injection....had i swapped in a 350 I'd be done by now and have it running..

DirtyComanche Posted October 26, 2005 Share Posted October 26, 2005 ...and then inject it with propane :D Isn't propane inconvenient in the states? Here probably ever 3rd gas station has it. I heard from a dude with an RV on propane that he had trouble finding places to gas up, and had to wait outside BBQ stores and crap. Link to comment Share on other sites More sharing options...
Bounty Hunter Posted October 26, 2005 Share Posted October 26, 2005 Many gas stations in the states have it, mostly for BBQ grilles and RV's. Popular with CJ's around here. Link to comment Share on other sites More sharing options...
whowey Posted October 26, 2005 Share Posted October 26, 2005 Many gas stations in the states have it, mostly for BBQ grilles and RV's. Popular with CJ's around here. We get it from Farm Supply. But if they are closed, most of the hardware stores here have bottle exchanges. Very few still have fill tanks. The gas stations have bottle exchanges only. And noone except Farm Supply or the propane distributor stocks any bottles bigger than 20lb grill bottles. Link to comment Share on other sites More sharing options...
DirtyComanche Posted October 27, 2005 Share Posted October 27, 2005 What's your price for it? Pay like .63 a liter here, 87 is at 1.08. Link to comment Share on other sites More sharing options...
Bounty Hunter Posted October 27, 2005 Share Posted October 27, 2005 whowey, where you at in IL? What farm supply store do you have near you? Link to comment Share on other sites More sharing options...
whowey Posted October 28, 2005 Share Posted October 28, 2005 whowey, where you at in IL? What farm supply store do you have near you? I'm up in Ogle county, in the NW corner of the state. We fill at the local FS dealer, they sell all the consumables on a farm. Unfortunately I live in town, so I can't have a large tank on my property. I paid .65 a pound, last time. But I know that the price is up now. We just paid .73 a gallon at work for the forklift tanks, so it is going to be about 85 or 90 cents a pound. 87 octane is $2.49 a gallon, but E85 is 1.95 Link to comment Share on other sites More sharing options...
DirtyComanche Posted October 28, 2005 Share Posted October 28, 2005 That's cheap! I think a lot more people use it here, might have something to do with it. Link to comment Share on other sites More sharing options...
Bounty Hunter Posted October 28, 2005 Share Posted October 28, 2005 We were just through there going up to Wisc. Dells and back. We're in Monroe Co. a little south of St. Louis on the IL side. Link to comment Share on other sites More sharing options...

The MJ isn't my primary trail rig, and far from my DD, so it isn't a big deal. I have 2 forklift tanks, and will probably get a couple more as spares, but for my uses, the two tanks are more than enough Link to comment Share on other sites More sharing options...
pingpong Posted October 30, 2005 Share Posted October 30, 2005 Around where I live.. There are several places to fill propane tanks, be it what ever size yoiu have. Also Propane powered forklifts are just about everywhere in the j-yards, so some parts can be found on the cheap. Patrick Link to comment Share on other sites More sharing options...
