I'd look for a GU4 optioned 231/3 speed car. That would give you a 3.23 axle ratio and a huge improvement in acceleration without a big drop in fuel economy. I paid $50 for the whole rear axle and it's the best bang for the buck I got for that kind of money. Mine had the 2.41 axle, but going to the 3.23 actually improved fuel economy around town.

would 3:42s work if i cant find the 3:23 optioned axle?
