transmission gear ratios

[Auto-X 240]

Anyone know where I can get the gear ratios for an S13 manual transmission that came with my SR20DET redtop? Also, are the gear ratios the same in the SR transmission as the Ka transmission? And yet another question: Did automatic transmission equipped 240s have a different rear end ratio from the manual 240?

Thanks for your help

I think I found the transmission gear ratios. Here goes:

1st 3.3212nd 1.9023rd 1.3084th 1.0005th 0.838reverse 3.382

These #s are from a CA18det manual. I ASSume the ratios are the same for the SR20DET.

The reason why I wanted these was to see what my top speed would be in 2nd gear for autocrossing. I want to avoid the 2-3 shift if possible. With a J30 diff with a 3.90 ratio it works out to 71 mph. Not perfect, but close enough. Anyone here autocross their 240s with SR20DETs?
