I recently bought a 1995 Wrangler. It has the 2.5L engine and manual trans. Sitting on 35'' tires it is quite possibly the slowest thing I have driven. It was regeared to 4.88 and it will get to 30 in a hurry, but anything after that is a no. There's a 3 mile flat stretch by me. Foot-to-the-floor, I was able to hit 60 after about 2 miles.
