My original 901 (never been rebuilt) tranny lost second gear. So I have found a loaner 901 transmission while I have mine rebuilt. I'm going to go for shorter gears. Can somone help educate me to options around shorter gears for a 901 transmission. I'm having a shop do the work but I want to educate myself to what track drivers think works best for gears. I have a 2.4 that makes something around 160 to 170 HP and use 265/45/16 tires in the rear. I will mostly be just having fun doing track days.

I failed to mention also that your redline is going to have everything to do with your gearing.

If a ficticious car was redlining at 4000rpm its speed would be hugely different than the same car runnnig at 8000rpm.

so if you aren't working from a dyno chart then your working redline has everything to do with the gearing you choose

my new tranny is amazing because its both a long and a short box in one, and really pretty applicable at all tracks with the FJOSV ratios
