Top Speeds

[cormac163]

Does any one have gear ratios for an early 901 gearbox.
Sorry here is some background.
1975 1303s Rack and Pinion steering wahey
Subaru Legacy 2.2l
Twisted Sanity NOS 100hp
Porsche 901 gearbox (early box with beetle flanges )
Porsche 911 seats, steering wheel, design 90 alloys etc
I am trying to work out what my top speeds through the gears are I know of a couple of calculators but what i dont know is the ring and pinion size of the box and the 5 different gear ratios either.
thanks
