Contact Racing Beat and Mazdatrix. They both sell pulleys.

Dear Paul
    I checked out the two co. you mentioned  and they have regular V
pulleys for auto use. What I am talking about is one flat belt driving
everything  plain and simple. Does any co. out there make such a set up. Has
any of the rotary people out there used alum under driven pulleys and if so
what has been thereopinion of them-  good or bad

The third gen RX7 uses the multi v belt almost flat pulleys.
That is it as far as I know. There are not a heck of a lot 3rd gens in
the country. Several people are using under drive pulleys.
Whether they are needed is still open to speculation.
My guess is they would more likely be needed with the new 2.85:1 gear box.

=============================================

Can a third generation 13B pulleys and belts be used on second generation 13B's?

If not, is there a serpertine under driven pulley set available for the the 86-91 13B engines?

Also, is there any serpertine system that will work on the 12A?

Thanks
Rich Gillen

I am not sure about that. The third gen water pump rotates 
in the opposite direction. Runs off the back side of the belt
as I recall.
