Need Advice on 4 Cyl Jeep

I am looking to get a relatively new ('97 and newer) Jeep Wrangler. My question is regarding the 4 Cylinder engine, I will mostly be doing trail driving through mud and sand in South Florida. Will the 4 Cyl. engine give me enough power and reliability to get me through? or are there any known issues with this engine I should know about. I currently own a Ford Expedition 4x4, which is a bit too bulky for some of the local trails.

Thanks for the help.

It certainly has less power than the 4.0L engine does. But if you don't go too crazy about big meats, it should do just fine.

Re: Need Advice on 4 Cyl Jeep

unfortunately, the place you notice lack of horsepower most is in mud. on rocks you can regear to make up for it, but in mud nothing will put you on the same level as a v8

Not sure if with respect to the sand, you are driving sandy trails or trying to climb dunes. Dunes favor speed and power. General trail driving and crossing obstacles require more finnese and skill than power. I'd be more worried about keeping up with the traffic on the highway if I had a 4 cylinder.

if you have about $5000 to spare you can slap on a supercharger which will put you at a claimed 210HP.... a lil pricey for me though...

Re: Need Advice on 4 Cyl Jeep

I have a 97 TJ problems off-road....running 31's on it and I will say that on the highway it's a lot of work to keep up even at 65mph with the small hills we have here on the highway....

Off-road I have never had a problem with it....

1. Welcome to the forum.
2. Thanks for filling out your user profile.

5. IMHO... the 2.5L engine is just too light for Mud and Sand.
6. I'd be saving for the 4.0L

Re: Need Advice on 4 Cyl Jeep

I own a 97 TJ with the 4 cyl and a 00 TJ with the 6 cyl. I put a K&N FIPK (fuel injection performance kit) on both engines. The kit is a tube with a cone air filter that replaces the stock air filter box. This made a very big difference on both engines. The best way to describe it is that it is like pulling a sock out of your throat. I run 31x10.50x15 on the 4 cyl and prior to the K&N it had a hard time holding 65 going down the freeway. After the K&N it not only held 65 but it would accelerate fairly well even up hills. If you can hold out/afford the 6 cyl you won't be disappointed. If not, don't buy a 4 cyl with automatic tranny, it makes the Jeep even worse. (I also own a Grand Cherokee Limited with the 8 cyl and put the K&N on it, I swear by the things. And no I am not a salesman for K&N). Airaide also makes a kit that is less expensive. As far as problems go the 4 cyl has 68k on it and the only things that went bad were the radiator top tank came unsealed (mainly because they are plastic) and the coil went bad. Other than that both have been real dependable. Good luck!

Re: Need Advice on 4 Cyl Jeep

My 97 tj with 2.5 has never disapointed me off road. However with 32.11-50 tires it now does not go down the highway near as well as it used to. I have been somewhat disapointed with it going to and from work. A set of 4:88 gears would help. Base thing is the 2.5 is a good motor for what it was designed for. I do not think I would be happy with mine off road if it consisted of mud and sand, but rolling through the woods up and down dirt hills with a little mud and sand is no problem...

Re: Need Advice on 4 Cyl Jeep

The Knee jerk reaction to hearing that you are going to be running mud and sand with a 2.5L is kind of scary. If you are seriously going to play in the goo, and the sand then a 4 dinger is not going to really do it.
It is a pretty horable feeling you get when you get into a mud hole and you engine just can't move the tires. If I were you I would hold out for the 6 cyl. You won't be sorry later on.
