I've got a 4 banger. It climbs and goes thru all kinds of stuff. It'll go really fast down 7% grades. On the flats I can go 50-65 but when I go to 5th, it bogs down. I didn't buy it for speed, don't care much after 50-60mph which it'll do. I sold my 300C hemi to buy this old jeep so I'm out of the speed business.
I've got 31's and no lift. Plan to go to Ourey and Telluride next week to run Ophir, Big Bear and other locally famous trails. If we want to really go somewhere we drive our Aspen with the hemi. We tow 4 wheels down, transfer case in neutral tranny in 5th with the switch set to acc. We can go fast towing but the jeep is like a brick when it comes to aerodynamics.

|Gate53||I was talking about the axel shaft. The nice part of stock is that everyone wants the "biggest and best" when everything else is stock why not use stock. They are cheap and easy to change. Junkyards are full of the stock ones. With oversized tires the axel is the first weak point so I carry extras I figure that if I upgrade those then I'm going to break the next weak point which is the pinion gear and I'd rather fix an axel that open the punkin. In a couple of years I plan on building a rock crawler. But, right now if I had the best there is I just don't have the skills to enjoy it. I think of my little 4 bangger as training wheels that can grow with my driving skills.|

thanks guys for the pointers.
and the axel you guys are refering to (the drive line? or actualy the axel in the differentials?

|Gate53||The thing about pics is that they never do justice to where you went, a "ya had to be there" thing. As for tips armor plate for the steering box, oil pan, tranny/trans case, differentials, and a spare axel for front and back d30 and d35. tow hooks front and back, a good strap w/loops,cheap CB, and lube everything with a zert. Then point it and go. Always go with someone else so you can pull each other out or give each other a ride. lol check for clubs in your area there's always someone that wants to go somewhere and they can clue you into what's around. Till you find out what your Jeep will do follow the herd. I found that mine would go 90% of where anyone elses would go. And 9 of the 10% wasn't the Jeeps fault I credit those to good sence. Enjoy it it's a fantastic learing experiance.|

|woodsballnc||I have seen many a 4 cylinder out preform a v6 or v8 on the trails. Mine is a YJ 4 cylinder and it does good on trail but getting driving it on the freeway sucks. But you can turn it into a really good trail machine.|

right on bro. lol you wanting to race my truck but u pick the track lol im willing to bet its off the pavement lol and then my friend thats when i have no room to brag cause my truck likes the pavement lol only time its seen off road is at my ranch
i do agree with you on the off road part i can feel were it has the power to handle that just fine.
and i agree with taking the truck on long trips or going fast.
any pointers you can throw my way on the do's and dont's on our tj?

I have a baby 4 bangger that I'll race your supercharged truck with as long as I get to pick the race track.
The only thing you can do to improve the preformance of the little Jeep is to take it offroad and experiance what it can do. The Jeep won't get any faster but the way you look at it might. From what I see as your setup that Jeep will now go places that you would have a hard time walking. You might pass me on the road but when you do you'll see a big shi% eating grin and I'll be thinking of the next trip off road or the last trip. What I'm getting at is they are built for 2 different functions. The 2.5 is designed to power the rest of the drive train in your Jeep and it does a good job without breaking things. If you up the power then you have to up the strength of the places that power goes. It is an ongoing battle once you start. Throw some armor under it and a spare axel in the back and have a ball offroad. If you want to take a long trip, or your in a big hurry take the truck.

|4Jeepn||It can handle a turbo, 505 performance makes one for it. Cost is 3-4k. Better off to get a 4.0L at that point.|

|haaswyk||ive got a 4 banger on 31's ... they aren't fast i push it to do 70 (down hill) gears will make allot of difference for you also losing any weight you can from the jeep will help.|
|08-13-2010 11:42 AM|
so basicly we gota live with the bs power.. see i was thinking of doing a small single turbo run like 6 lbs of boost what can and what cant the 2.5L hold?

I hate to say it but short of regearing both axles to a slightly lower ratio (which I would not do for only 31" tires) or installing a supercharger, there's nothing you can install that will help. Not an air intake, not headers, not a K&N air filter (don't EVEN install a K&N air filter) not a throttle body spacer, not a larger throttle body. You can only make sure it is running as well as possible with good plugs, distributor, cap, clean air filter, etc.

|02maddness||So on the intake portion on the motor, theres a small little intake tube coming off the air filter box the id is like the size of a quarter can that be removed for added throttle response that and spark plug recamendations?|
|08-12-2010 01:05 PM|
I couldnt agree more. on the exhaust and intake. I just dont know the do's and dont's of the jeep.
Angeless: the tires are 31x10.5 R15 LT Dunlop mud radial to my understanding i was told these are stock tire size the the jeep just a more agressive tread pateren.
but as i am a Ford guy i have a 2002 F150 harley davidson SuperCharged truck and i know the slightest tire change in size can effect my et's on the track.
and Wes i know bout the good ole cj's with the Ford powered engines.
and thank you guys for helping out.

You will be happy to know that Ford made lots of Jeeps in the early days and in the 60's and 70's in Australia many were sold with Ford motors.
Every time I see the words 'performance mods' in a Jeep thread I check it out hoping that finally there is a verified, documented, worthwhile, useful upgrade only to be dissapointed yet again. Then I get a big warm fuzzy feeling thinking of all the other reasons I have the Jeep for.
|08-12-2010 04:59 AM|
The 4 cylinder is notorious for it's lack of power. They do well off road though, as long as you don't want huge tires. What size tires are on it now? That could be affecting your highway drivability.
|08-12-2010 04:31 AM|
How does it run at all without
a exhaust or a intake??
