? about 4bangers in jeeps

hey yall, ive been a member on here along time but I troll on cherokeetalk mostly since that's what I own, im not here to talk bout the xj though, I bumped into a fellow with a 90 [ I think he said 1990 ]wrangler man.trans 4wd 4banger with 200k on it for 2500obo, I think I can get it for around 1800 though, he wants it gone, a older genltleman owned it most its life and used it in town, someone cut the side pass. window with a blade recently, pass.side front fender is bent a little and has some rust, fires rite up ,no smoke, no knocking, no leaks , its dry underneath and the frame is rust free [ been here in s.c its whole life], I have the 4.0 in my xj and its a beast still with 180k on it, my question is are the 4bangers as reliable as the inline 6 ? Im not a mechanic by any means, I do as much as I can in my yard,, but rebuilding or pulling motor, trans. etc. is way out of my mechanical skills, I like it a lot and heard it run but I haven't drove it yet but that's a must before I do buy it, does the 4cyl. have as good of a rep. as the 6, and what would be the pros and cons if I do purchase the jeep, thnx for any input guys and gals

The 4 bangers can be just as reliable. The downside... Less power and not really any more fuel efficient than the 4.0.

You do get 4:10 gearing tho. As mentioned they are underpowered and not particularly fuel efficient. If you like it. get it and learn some mechanical skills!

Wheeled the hell out of my original 93 YJ 4cyl. Mileage was up to 160k when I got it, but over half was flat towed. I noticed the loss of power when loaded with people, uphill at high speed, or trying to tow a midsized trailer. If you lift and get heavier wheels, regearing will be more critical than with a 6cyl.

For just me in highschool? I had no issues. That engine was reliable all the way until the next owner (a relative) ruined the body and interior. My biggest reason to upgrade was a worn out factory top and no A/C (it gets HOT here in the summer while raining!)

My first Jeep was a '95 YJ with a 4 cylinder and 29" tires, and it had plenty enough power for 5th gear on the road. Reliability with the 2.5 is probably almost as good as the 4.0 6 cylinder, and you routinely see them with mileage over 200k. Mine had 150+ when I bought it, and never had a days trouble with the Jeep. In fact, I wouldn't hesitate buying another if the price was right.

My 98 and 95 wranglers were 4bangers they are reliable engines. Just as reliable as the 4.0 and 4.2l I6's. As far as power is concerned your not going to shatter and records. But with proper gearing they are great.

4.88 gears and 33" tires are the sweet spot for the four cylinder Wranglers. And people with six cylinder Wranglers change their gear ratios too, so it's not just a four-cylinder thing.

^ This is true, I am going to change the gears in my 4.2 from 3.07 to 4.10 soon as I install my lift and 33's

I agree with these guys my 97 four banger had 160k on it when I got it and ran just as good when I got rid of it two years later with 193k. I would probably still own it had it not had the 3 speed. I never had any issues with it.
