If you have a 3.91 now, going to a 3.23 would be worse. I have only looked into this for 5 speed manuals. Im guessing you have a 4 speed auto, so your tranny gearing ratio is way different than a 5 speed manual. Im thinking that this would reek havoc on your auto tranny if you played around with the gearing ratios.
