Stock 4cyl engine 5spd in my 97tj. Regeared to 4.88 to handle my 35x12.5 tires. No problems off road, bit I don't rock climb or do any steep hills, I live in south jersey so neither is a big issue. As for speed, yeah her name white lightnin is a bit of an oxymoron, but I didn't buy it to cruise 75 or better on hwy. I would buy another 4cyl in a heart beat. But like most things, personal pref. Is just that.
I have a 1997 TJ with no engine mods, 4"suspension, 2"body, 35x12.50 R15 BFG MTR's, 4.88 gears, 1.25" wheel spacers, locked front & rear etc
I struggle to climb hills on the freeway and headwinds are my worst enemy. Offroad - I have only outperformed or matched i6 Wranglers with the same general mods. Every time we go wheeling they're kind enough to let me and other 4 bangers lead the pack (on paved roads) because they know that we can't drive too fast.
I am looking to do an exhaust modification. I will seriously consider any suggestions/recommendations.
I'm in Florida. Got an 04 TJ 4 banger and love it.
I don't do much offroading other than cruising dirt roads in the woods around here and driving on the beach in St. Augustine, so smaller 235 75 R15s are all I need.

OK, Well I think something is wrong with my Wrangler (4.0/NV3550) when 4 banger owners start saying they can cruise to 75 easy all day when my 4.0 struggles at that speed, overtaking is painful, starting to think I'm not getting the power the 4.0 is supposed to put out? Bruce Lee says I can't compare it to anything because I've never driven anything else, or something like that.
Just because you can doesn't mean you should.
I have been in my friends 4 and my other friends 6 cylinder to be honest and in my own opinion I think the 4 banger is fine and has plenty of power in it. I also have a 4 banger I'm fixing up because I got it for cheap and am making it my off road jeep. The one friend that has the 6 cylinder swears by it but he doesn't know what he is talking about. Imo the only difference between the 4 and 6 is highway and hill power but off road they are semi the same and can do the same things. Also the one downside of a 4 banger is there aren't as many options on engine upgrades for it compared to the 6 also offroading u don't have to worry about the 2 extra cylinders and don't have the extra weight of them
My question since I cannot compare a 4.0 vs 2.5(never drove a 2.5 yet) is why did chrysler designed both of these types of Jeeps?
I own a 4.0, and I'm not saying anything is wrong with the 2.5 in any respect but when I started to look for my jeep last summer, I was told that I would be better off with a i6 engine because you dont want to end up flooring it and having that extra amount of torque would less stressfull on the 4.0 (in theory). My last truck I owned was simply a 3.0 Mazda B3000(rear wheel only) standard 5speed. So to me going 2.5 from 3.0 wasnt a logical choice.
Wanted a TJ. In my area, the 4.0's were going for 2-4k more than lower mile 2.5's. For my purposes, a 4-popper was suitable. Would I have taken a six??? Absolutely! Not for several grand more up front though.
All I use it for is driving around in the summer, and light off-roading on private property.
I had it re-geared to 4.88's, and added 30" Mud Rovers. This actually results in it being a bit "overgeared," but it'll run 65-75mph, even up the "hills" found around central Wisconsin.
The doors, rear seat, and soft top are all history. I store it in the winter, and it stays inside when rain is in the forecast.
I drive it as often as I can (coldest - it was 29 degrees when I left the house, but warmed into the low 60's during my workday).
