Give up on straight 4 TJ?
 
I bought this 2004 Wrangler Sport for 8000 with 36000 on the speedometer at the end of 2011. I've put over 30000 since and I love it. I need a new top, it's dry rotted. Someone broke into it by cutting the plastic passenger window but it just can't keep up with highway speeds. When I was in high school (living on the farm literally) we would have just put a straight 6 in it and been done with it. I found a straight 6 with under 40k in a salvage yard and started calling around to find a shop that would do it, none would!

I just need to not drive it in 4th all the time to get to 70mph. I can still get it to 85mph but it won't cut it around Houston and that would be 1 1/2 hrs to work and back.

Everyone says the cold air intake will not do any good. so I'm thinking about trading it and a 1997 bmw roadster I have in on a new jeep wrangler but they don't have a total soft model. After the 22,500 for the basic package I'll have to change out the radio for a usb aftermarket one (or buy the model with it for 3000 more) The doors are coming off.

A local shop suggested that they could rework work the engine (oversized cams etc) for about 2.5g-5gs and that seems like a lot.

How about some suggestions. :whistling:

Thanks,
Bubba

I also have the 2.4l... Plenty of torque off road but good luck getting it up to highway speeds. I know your pain, I have been thinking about trading it in for a WHILE but I have put too much of my time and money in it now and I am really attached to it. I went to a local 4x4 off road shop and they quoted me at 5k to swap to a 4.0l. That includes a new motor as well.

I am now saving up for it. A LOT of people on here will tell you that its not worth the swap for only 40-50 hp gains but I have driven my buddys 4.0l and its a big difference.

Went o the best and oldest engine and transmission shops around this area and none were willing to consider it.

Should have the 4.0 in it. Check the VIN. Either somebody swaped the motor or you do not have the "Sport" trim package. Also do you have a lift or larger tires. If so, look into regearing.

The title, the feature list from jeep and the car fax reported it as a 4 cylinder jeep sport, trail rated.. There are no signs of a sloppy swap on the engine.

As previously stated: Gearing, it's a bigger deal than power.

Keep in mind, I have the 4.0 and it was one of my criteria that was not up for compromise when I was shopping for a TJ. However, if you have the 2.5 and have issues driving it due to someone putting big-ass tires on it that it's not set up to run properly, gearing would be a step in the right direction mist likely.
