I just recently saw a Jeep wrangler Rio grande Edition Standard. The car is beautiful, silver no rust and is intact from the inside. The upholsetery is just a bit dirty, but thats about it. Her car is lifted and I believe it has 32" or 33" wheels. I tried the car out and it seemed to run good. I know wranglers are heavy, but when I we tried it in the freeway the car wouldn't go above 50 or 55 mph going up the little hills. I was wondering if this is normal for a 4 cylinder wrangler because of its weight and the lift. If it is, what parts can I add that are not that expensive that will give the engine that expra hp push to take the car up to lets say 70 mph. Just enough to ride it in the freeway.
first off its a jeep, i think...haha, those four bangers are a little underpowered and any changes you make to the engine will probably only due more harm then good, from what i have read and experienced. on flat surface with stock tires you should hit 70 or 80 but your driving a brick (aerodynamics ) and a jeep is relatively light it should say on the inside of the drivers door. but i think it is in the mid 2000 lbs. so anyway hope that helps, i don't know much....
" Crocs have the rare combination of being expensive, poor quality, and ugly. It's quite a feat for one shoe to suck this bad." -some bad a$$
i have a stock yj 4 banger, motor wise, and today i was doing 70 no problem. I run 30's on it and a 4 inch lift with stock gearing, pretty much running it out but it will still do it, in 5th gear at like 2500-2800rpm it will run at like 65-70 but the speed really reduces over hills or over passes or anything of that nature, just the way these 4 bangers are
skip the highway and take side streets. More fun with the top off anyways. I have a 95' Rio Grande with pretty much stock everything and mine hits 70 no problem. Looking for tires though as we speak, I wont miss going 70 if I can get her some swampers.
Nothing you can really do will do what you want. I spent alot of money trying, then I spent another 3000 putting in a vortec V8. Its much better now, infact the other day I smoked a little black mustang off the line !
side roads are good right up untill i have to get to school thats 20 minutes on the highway lol i love the jeep though so i dont car about the speed, and i agree on little roads, pretty fun to drive on with the top off
Well, Im planning on using that jeep for college. My only problem is just the doubt wether the wrangler 4 banger can go on the highway for 6 hours with no problem... Anybody know? I don't have a problem with the car going slow, I don't need speed. I was just wondering if it was normal for the jeep to do that or could have there been something wrong with the car, but this pretty much clears it out. Now Im just wondering about the traveling. I know it won't be comfortable, but that's not the problem either. Just want to know wheter the car would be able to travel the six hours with no problem?
I have a '95 YJ 4 banger and it does 70 without much of a problem. Now - 80 may be a different story.
Anyway, the reason you have a hard time getting any speed up a hill is because the little 4 banger just doesn't have the torque to motor up the hills - even in 4th gear - especially with 32 or 33" tires.
I have 30s on mine and will downshift to 3d sometimes merging onto the interstate ramp or hills on the interstate on the way to work.
Also, consider that you may actually have been doing 60+, since the larger tires will throw off your speedometer. With the 30s on mine, my speedo is off 9%.
The best way to get an actual speed with oversized tires is a GPS unit. Then you can compare the two and find out the % your off by.
had the same problem in my 90 YJ 33.12.5 tires stock gears at first would if I was lucky to get to 60 flat out with a tail wind pushing, went to 456 gear ratio now I'm pushing 75-80 mph and yeah she's squirly at 80 mph and I changed the speedo gear so I wouldn't get a speeding ticket so mph is actual. at 80 mph I am at 3000. rpm and at 70 I am at 2500 rpm.
