No, I don't know the ratios of either box, last time when I had them checked/re-built the guy was supposed to note them but forgot.

I know the rally box is a kit ex Reg Cook.
The race box is interesting because I've been told its a collection of gears from other nissan boxes i.e. the first in my box is actually second gear from a vanette or something like that, my race box goes back to shell sport days, where I believe Reg built 4 or 5 of these boxes and mine is the only one known to still be in use (A year or two back, Reg was very keen to get it back into his possion, but couldn't do a good enough deal on a replacement box for me).
