Need opinions on 4cyl vs 6cyl

So I'm in the market for a TJ and found one that is super clean with low miles, and at a fair price. However, its a 4 banger, and I want a 6cyl just for the power, cause I have a 4 cyl truck now and it has about 180hp which is close the hp on the 6cyl wrangler is that correct? Is there that big of a difference in between the 4 and 6 cyl not in numbers but in the actual feel of the power, if that makes any sense... Please post your opinions between the 2, and if I should make my choice just on the engine size. Thanks for advise.

Jeff

Do a search. Most people will tell you to get the 4.0. I was in the same situation as you and I just waited for the right 6 cyl Jeep to come along. No regrets

Just bought my TJ yesterday (6Cyl) i was looking at both and drove both. The 4 banger is a little sluggish -especially when there are mods.. like a lift .. 33's, heavier bumpers.. etc. But that is how it felt to me. If i found a good buy and it was a 4cyl, and i did not mod it much, then it should be fine. But i wanted a 6.

Hmmmmmm..... let me put it this way:

The 6cyl is like an energenic squirrel

The 4cyl is like a panting chipmunk

i've had, and do have jeeps with both motors. the 4 cyl is just as reliable and long lasting, but its a dog. i will not buy another 4 cyl, unless its too good to pass up.

tons of people that buy the 4 cyl start asking how to swap it later, and there is no cheap, quick, or easy way to change. buy the 4.0, and you will be happy.

The 2.5 will have a little bit more than half the torque the 4.0 has. Just on casual driving the engine will be screaming just to keep up with traffic. And i also heard that the 2.5 gets the same mpg as the 4.0 because you have to run it so hard to get to highway speeds. I heard people saying that with their 2.5s they have trouble getting to 75mph but with my 4.0 i got to 85 and it could do alot more.
I say wait a bit and go for the 4.0 and you'll have no regrets.
But do whatever you want "to each his own"

Ok, so it sounds like the 4cyl wont be worth it, cause I plan on putting a lift, bigger tires, bumpers, etc... Thanks for the advise, and I will keep looking.

I have never heard of someone regretting getting a 4 banger over a 6 cylinder, but lots regret getting a 4 banger over a 6 cylinder.

My TJ has the 4 cylinder. For normal street/road driving it's fine but when I get on the Interstate I wish it had the 6 cylinder.

I bought a 4 cylinder and no air conditioning because I was only going to use it once in a while for some fun. I liked it so much I started driving it a lot. However, I wished I had the air conditioning for the the hot months and the 4 cylinder was extremely underpowered. I sold it after 4 months and bought my 99 with the 4.0 and all the other options and love it. Go with the 6 cylinder.

Take it from someone WITH the 4banger... get the 6. I hate how slow my 2.5 is sometimes. It's cool because I'm never really in a hurry to go anywhere, but that doesn't take away from the fact that I'm starting to get my list together of stuff I will need to put the 4lt in my tj this summer. It is bad enough that I am putting my turbo R1 project to the side.

4cyl will give you the power you NEED to pull your vehicle.

meh, even the 4.0L is sluggish as hell. It doesn't help that the one I drive is attached to a 3 speed auto, but still, it sucks. I think my s10 with a 4-banger will accelerate faster.

But between a 4 and a 6, I'd NEVER go with a 4 again. Leave the 4-bangers in economy cars.

Shocked by how many people say the 4 banger is underpowered. Mine is stock, and will probably stay that way, and I have no problem doing 75 on the freeway (and frankly, in a gardening shed on wheels, I don't want to go faster than 75). I slow down some pulling hills, but not bad ... and I sure as heck HOPE I am getting better mileage than the 6 cylinder.

The 4 cylinder does not get better mileage than the 6. I have had both.

4cyl doesn't get better mpg.. it has to work harder and therefore uses more gas.

It's a 2001 Sport, and I want to say it has the 3.73 in it. But it's on 31's and not 30's.

But as far as gas mileage, it's non-existant in a jeep. They all get crappy mileage.

Mine is a 2000 Sport 4.0 Auto with 31" tires and I don't have any problems. If the AC is on it's a little sluggish on a large hill from 0-50 but nothing major. I mean it's not GT Mustang, but it's as good as the 4.0 Ford or 4.3 GMC I used to have.

my 2.5 gets 18 to 20 mpg with 31"s I guess it depends how you drive. i have had both too and i picked the 2.5 for the better gas mileage.

I've driven both the 4.0 ford (03 ranger) and 4.3 chevy (99 silverado, 95 4x4 blazer, 00 Safarri, and many more). The Chevy had the most power and get up and go from my expieriences. And all had autos, so that's similiar. The ford came in second for me, the jeep's 4.0 disappoints me, it does fine once at speed, but accerleration sucks IMO. I prefer a 99 extended cab full size chevy with a 4.3 over the wrangler, but I can't beat the "fun" factor in a jeep.

On topic: The jeep gets about 16-17 mpg, mostly highway. So it's not really worth it to get MAYBE 3mpg better with a 4-banger. Get the bigger engine and if you need it, you have it. Especially if you do decide to go offroading or need to pull a trailer, you have the options.

This makes no sense to me ... the 4 banger has to work hard to do what? Accelerate to 75 in the same amount of time the 6 could do it? I don't drive it like a race car, nor do I floor it every time hoping the 4 will accelerate as fast as the 6. Anybody got real statistics on what the MPG is between the 4 and the 6 (I'm gonna start tracking mine, and if I don't get more mileage than the 6 I am gonna be seriously annoyed).

I have the 4 cyl. for my needs it works great. Can do 75 on the freeway if I need to. I mostly use it to tow behind the motorhome and then drive around when I get some place. As far as off roading....it goes just fine for the trails I do. I not a rock crawler or mudder so it's perfect for what I do. I would have gone with the 6 but this one came along, was real clean, drove real smooth, looks like new paint.....and was the right price.

If you plan on a daily driver or doing more crawling or mods....I say go with the six, but if it's just for fun the 4 is fine.
