2.5 4 Cyl TJ vs 4.0 6 Cyl TJ. What do you think?

My dream vehicle is a TJ with the 4.0, buuuutttt there's a sweet deal on a 2.5 TJ in my area. Seriously thinking about getting it.
I currently have an '04 WJ with the 4.0L and I'm really happy with it as is, but I'm wanting to get a Wrangler.
Has anybody went from one of these engines to the other? For those that went from the 4.0 to the 2.5, What do you miss? Those who went the opposite, What are you glad to have?

Guaranteed opinion-based argument right there.

Go test drive the local four banger and form your own opinion -- you're the one who'll be paying money for it and will have to live with the decision.

Had a 2.5, was fine around town and off road, the highway it was terrible, I was getting passed by RV's. and hills or into the wind

Now I have a 4.0, more 'power' and torque than I need, 80+ on the highway

Also went from a soft top to a hard top, same thoughts, night and day

What kind of driving and what kind of mods do you plan? And just fyi the frames are different so if you are considering "I'll just swap it down the road" it don't that easy. I say do the 6 banger.

Hold out for the 4.0L, especially if you plan on modding it down the road.

After the new wears off you will wish it had the 4.0 every time you see it and be disappointed. A swap is a terrible idea down the road. I think it’s a bad idea and you're hoping to hear it will be ok if you get the 4cyl.

Newcomer here. Before I bought my 2000 in 2004 I test drove several 2.5L models. I didn't mind them for in town driving, but I felt like I was being blown all over the highway at speed.

I jokingly say that every time someone turns the key on a 2.5L engine the baby Jesus kills a dolphin.

"buuuutttt there's a sweet deal on a 2.5 TJ in my area"

There is a reason why it seems like it is a sweet deal. Ask yourself why that might be. Unless you plan to leave it stock and drive it mostly on city streets, the day you buy it and the day you sell it will be some of the most joyful days of your life. It would be for me anyway. Your mileage may vary. How do I know? Based on comments from people who valiantly try to go wheeling even moderate rocky terrain. Will never forget the time one such Jeep had to be towed by another (4.0) through some rugged and steep hilly terrain, late into the night.
Even with the 4.0, once you start to pile on the mods, most anyone is going to wish for more power. A 2.5L? Good luck with that. Sorry 2.5L owners, it is just my $.01 opinion. To each his own.

My first Jeep was a 4 cylinder. I ended up trading it for something more useful.

When I was TJ shopping, I had a list of "must haves", a list of "don't cares", and a list of "absolutely nots". And I stuck to it, and still happy with my purchase and TJ over 12 years later, no second guessing or regrets.

OP, if this 2.5 is such a "sweet deal", buy it, drive it around while you look for "dream 4.0", and then sell the 2.5 for a profit.

I am multi-talented, I can talk and piss you off at the same time.

Unless it's in VGC , under 100,000 miles with AC and under $3000, there's no profit to be made where I live. I had one and made a profit after driving it over 2 years. Mine are pretty though.

If you gear the 2.5 Jeep properly for the tires you chose, they're not too bad. Folks with 4.0 Jeeps regear their Jeeps too, so it isn't just a 2.5 thing. Geared properly for tire size and with lockers, a 2.5 will pretty much go anywhere a similarly equipped 4.0 Jeep will go off-road. It isn't just about the engine size off-road; it is also about traction. And geared properly for the tire size, fifth gear is also usable on the highway.

As already mentioned, go take the 2.5 for a test drive and see what you think.

Hasn't this been beat to death already numerous times? Does somebody not know how to do a search? Or they think their question is different from every other time this question has been asked?

Pictured is a 2.5/five-speed TJ with 33" tires, and 4.88 gears with lockers front/rear (Dana 44 rear).
