2.5 standard vs 4.0 auto

I'm looking into picking up a beater to go sand dining and possibly some rock climbing. Won't be a DD and only highway for about 15 min. Once or twice a weekend. Based on the two best xj available on my area one is a 2.5l standard 3" lift and 31" tires and the other is a 4.0 auto 3.5" 35 tires. Which would you pick and why! Thank you

Hmmm if you can prove the 4.0 had it's mods done right that's a good set up. But I'd be worried to buy a modifies jeep off of Craigslist because there's a lot of ways to lift jeeps and for big tires, but few ways that are reliable and correct.

I would take both to a mechanic as part of the conditions of the sale, and have them checked out. Either would be fine, but you never know what the PO did to it. and you could have a lot of redoing or just a lot of work in general.

I understand and If they have nothing to hide they won't object to tAking it to a mechanic. With regards to the engine tranny situation which would be preferred for what I would like to do. I've read most say 4.0 but the one I found is auto and the 2.5 is standard. Not many choices here. 2.5l Standard is about $400 cheaper leaving $$$ to regear.

I'd be happy with either the 2.5 or the 4.0.

What are the years and condition of the vehicles? I would go with whichever is in better condition, most will knee jerk and say go with the 4.0 just because it has a little bit more power. But I would rather have a functional Jeep with low power, than a bucket of bolts with more power.

either will work if they are done right. if you want a standard, buy the 2.5 and just be prepared to take it slow on the interstate.

If the question is based on the motor and trans combo, I vote 4.0. I would be happy with either a 5spd or auto trans, but do prefer the auto offroad. The 35" tires have me concerned, but you could always buy a tire to more accurately fit the rest of the rigs set-up. IE, gearing and whether or not the axles have been upgraded.

The 4.0 one if you're wheeling it in rocks. The 2.4 is the same motor just less 2 cylinders. It's a good motor but I wouldn't want to run bigger than a 33 or in rocks with one.

The 4.0 auto was crap. I went to see the 2.5l. It is a 1986. Drove fine. 4lo had a wine noise but didn't grind but did make the jeep feel real heavy and slow to move. I never fully understood 4lo,I always drove in 4hi sand trails. 4hi seemed great. Ac didn't work or blow air so I'm guessing a new blower as well as a r134 conversion

Sounds like it might be best to keep looking unless the 2.5L is $1,000 or less.

Agreed. The 86 is still renix era (I believe) and those engines have a bunch of... Personality haha

I paid $500 for my unmolested 89, I've put another $600 into it. and got a good running jeep. Its not lifted or anything, but all the parts and bits work. I'm sure you can find a better deal out there.

Yea I would even pass on a Renix 4.0 unless it was a good deal or in immaculate condition.

4.0 didn't come out til 87. Only downside to Renix is the ****ty cooling system.
