cosmo
 

what year to what year did mazda produce the cosmo? and what was the hp rating on the 3rotor 20b?

The 20B produced ~276hp. They started having the (JC) Cosmo's in 1990 to early 1996.

thanks!

I think you will find they produced closer to 300-320HP, 276 is just their rating on paper thanks to silly rule in Japan.
