Question from a newbie---
    On a Mazda Rotary engine, what do the terms "13B Street Ported Side
Plates" and "Fc3s" refer to?

Street ported means it has been souped up by streamlining the intake ports.
There are a wide range of street ports so it is hard to predict what
the power would be. I would keep it down to below 150 HP if it is
a pre 89 engine for reasons stated in the lest message.

You got me there on the Fc3s.
