    Yes, I'm looking for 2 gear boxes for a 250 H.P/engine twin with about
2.5-1 ratios.

Ok. As it stands know I think you will have to design and build your
own. BTW 2.5:1 sounds ideal for a rotary however.

The Mazda rotary will not run backwards like a piston engine will.
Nor is it a good idea to turn it around and take power off the front.
The front part of the shaft is way less strong than the back part.
