97 TJ 2.5L performance parts
hey all,
Last week purchased a 1997 Wrangler SE (2.5L), automatic transmission. It has large 32" tires and lift kit. Nice looking but performance is poor. If I could eek-out another 10-15 horsepower it would be much more drivable around town and on the highway. My questions are: Does anyone have experience with performance mods; air-intake, exhaust, etc. for the 2.5L 4cylinder? Also, how can I tell what gear ratios I have? Judging from the performance with the 32"'s I'm guessing I have the stock Dana 35's. ... ( 0-60 in about 5 minutes on flat ground. No chance of even hitting 60 on a hill :) Any opinions on reputable/reliable JEEP performance parts places? I have no books or documentation on my JEEP yet but I am learning about it by trial and error! Any help would be appreciated. Someday I will be able to give back! TJ |
Re: 97 TJ 2.5L performance parts
Put the stock tires back on it, and get rid of the auto.

As for the tires...well...I'd like to keep them. So any performance minor mods available while still keeping the auto and 32's? Thanks, TJ |

Re: 97 TJ 2.5L performance parts
And the re-gearing will run $400-$500 for parts and that same amount for
labor. None of the other 'bolt-on" products will get you the necessary power out of the 2.5 liter engine. Your differentials should have a tag that shows the gear ratio, if not you can get a "Build Sheet" from your corner DC dealership... all you need to provide them is the Jeep VIN number. Build Sheet: http://s112.photobucket.com/albums/n...Build%20Sheet/ Axle ID and Gear Charts http://s112.photobucket.com/albums/n...06/Axle%20IDs/ Once you know your stock gear ratio there are charts to point out the appropriate new ratio given your new tire size to regain 'stock' performance.

Better gas mileage wouldn't hurt either. Worth the try at least. Regearing the axles does make the most sense. I just need to figure out what I have and how to change them. I'm not looking for much performance gain. Thank you for your advise. I much appreciated it. TJ |

Re: 97 TJ 2.5L performance parts
Normally the 2.5L engine with a manual will be geared at 4.10's, but I guess
they may have 3.07's with the automatic (the auto 4.0L does). You would want to get at least 4.10 gears. If you already have 4.10 gears, consider 4.56. Your transmission doesn't have an overdrive, so after you regear get used to your tach being at around 3000RPM at highway speeds and your gas mileage going south. You'll also need to replace your speedometer sender gear with one that will compensate for the new gears. The shop doing the gears can do it. <hammertc2000@yahoo.com> wrote in message news:1172350151.251419.221200@m58g2000cwm.googlegr oups.com... > On Feb 24, 2:31 pm, "Earle Horton" <graci...@usa.com> wrote: >> <hammertc2...@yahoo.com> wrote in message >> >> news:1172344565.073873.112240@8g2000cwh.googlegrou ps.com... >> ...> Yes, I guess your right, getting rid of the auto trans and the 32's >> > would improveperformance:) >> > Unfortunately, getting rid of the auto trans is not an option as I >> > only have one leg to drive with.

Normally the 2.5L engine with a manual will be geared at 4.10's, but I guess
they may have 3.07's with the automatic (the auto 4.0L does). You would want to get at least 4.10 gears. If you already have 4.10 gears, consider 4.56. Your transmission doesn't have an overdrive, so after you regear get used to your tach being at around 3000RPM at highway speeds and your gas mileage going south. You'll also need to replace your speedometer sender gear with one that will compensate for the new gears. The shop doing the gears can do it. <hammertc2000@yahoo.com> wrote in message news:1172350151.251419.221200@m58g2000cwm.googlegr oups.com... > On Feb 24, 2:31 pm, "Earle Horton" <graci...@usa.com> wrote: >> <hammertc2...@yahoo.com> wrote in message >> >> news:1172344565.073873.112240@8g2000cwh.googlegrou ps.com... >> ...> Yes, I guess your right, getting rid of the auto trans and the 32's >> > would improveperformance:) >> > Unfortunately, getting rid of the auto trans is not an option as I >> > only have one leg to drive with.

You can't have performance and 32" tires.

Re: 97 TJ 2.5L performance parts
You have 4.10 gearing. 4.56 will return some performance and gas mileage.
Get the 4.56 gears, cat-back and 4.0 throttle body, and be happy. FWIW, my 89 YJ 2.5L pushed my 33's around town and on the highway with no problems, but it was a five speed. The 2.5L is a great engine.

In the meantime, I looked today at the rear differential cover. It definately has Dana on it.

I guess I was actually doing 68MPH. Good thing the speed limit on that stretch is 70. TJ |
