All depends on how one takes care of their engine. Same with everything, including the 4.0.

Running circles perhaps, better re-sale value depends on location and the buyer..

But my 5.2 runs circles around both the 4.0 and 2.5

My stock 2.5l got 14.5mpgs. My 4.0l with 4.10 gears and stock tires got 20. It gets 16-17 on 35s.
Sounds like your 2.5L was neglected badly, as was mine. Mine had more than enough power to lay down 11's on the tarmac for a decent distance if I tried to, and I never had any issue whatsoever breaking the rubber loose offroad, doing donuts, slides, etc.

I don't know what y'all are sayin' about the 6cyl being slow... Haha! Maybe compared to cars at highway speeds... But I've beaten ricers off the line and past a block distance in my YJ with 33's. Plus the I6 is just about invincable.

Granted - if you already have a good 2.5L there's no sense in making the SWAP... But I'd take a 4.2L over it ANYDAY - I've driven a 2.5L TJ, and a JK with their 3.8L and they both were a totally different experience for me - hated how sluggish they seemed... (Granted they were both automatics and my YJ is a manual - don't know if that makes much of a difference or not...)

I don't know about that
My friends 91 2'5 has about 230k on it with no issues at all. Still runs great actually. His 99 4.0 is going to die soon with the same mileage. All about how you maintain them

I base my findings on the jeeps I have had over the last 4 years (52 right now). I have had one 4.0 that knocked, 7 2.5's with rods hanging out the side, 3 2.5's that had valvetrain noise, and 1 2.5 that was running perfect and blew up on me as I was driving it into town.

LOL 5.2, you coulda done way better than that thing Xpress

Sounds more like you are just looking for excuses to flame the 2.5L. You cannot deny its robustness. For the 11 2.5L's you've seen, you've missed out on the millions of other ones you have not. Stop pretending like you know the 2.5L is garbage. There's more than a handful of locals rolling with the 2.5L with well over 200K on the clock.

Internet heresy goes a long way. I've heard several 4.0's that were knocking, one was trashed and spitting oil, going to the junkyard I've seen 4.0's with rods out the side (far too many to count), 4.0's with cracked blocks, scarred pistons, and one even had a head that was split right in 2.

The automagic slushbox kills it. I've driven enough auto and manual 2.5/4.0 TJ's and enough 3.8L auto/manual JK's to know this. Not enough gears with the auto.

And not saying the 3.8L gets better, it really doesn't, but the manual makes it bearable to drive.

Im not pretending anything paco, proof is in the pudding. Why do you think the 2.5 motors are worth twice what a 4.0 is? Prolly cause the cores are more money, because a broken block isn't fixable Trust me, I love the 2.5 jeeps, they put food on my kids table....but as far as them being a good purchase to drive and keep? Not a chance. And its not 11 2.5's, just 11 broken ones out of the 25 or so I have had.

2.5l on 33's and I love it! Its fun to play the drafting game on the highway to break 70 MPH. (No, I do not have a death wish - handles like a dream on the highway!)

Just because you have an opinion on the 2.5L does not make it a fact. There are MILLIONS of 2.5L Jeeps still on the road today, and that is a fact you cannot deny.

As I've said before, my 97 2.5 manual won't go anywhere fast, but it will go anywhere. I, too, have thought about moving up but when my only criticism is "it isn't fast enough", I catch myself. It's not my regular DD. I don't care about fancy interiors and fancy switches and knobs. I drive it because it's fun. It may take me longer to get "there" but if I'm on a schedule I just leave early. It's pretty much stock except for 32's and a small body lift. I've accidentally wandered onto some "more difficult" stuff that may have even been black diamond material and lived to tell about it. For me, it's just fine. As another person posted, we're both old and slow so as long as it gets me there and back it's all good. I know this will earn me scorn as a Jeep owner, but...<ahem>...I have other things to spend my money on <don't hate me>.

I have owned 2 2.5l powered Wranglers and now a 4.2L wrangler. The 2.5 is a great little workhorse but when it comes to power there is no replacement for displacement ! I'll admit when I was looking for another YJ. I looked at 4 bangers and 6's. I got a 6 since it was a cleaner Jeep and better price.

Both of my previous Wranglers had 4.88's and 33-35" tires. My TJ the engine spit a piston through the block at 83k miles. It was replaced with a junkyard block and 505 performance stroker kit. It really woke it up however the tranny didn't like the extra power and it went kaput 3 weeks later. But it still did not have the low end power of my 4.2l. On the hiway the 4.2 does get to speed better and I will say my XJ will walk away from the YJ on the hiway but getting to hiway speeds the XJ and 4.2 YJ are about the same.
