hi, are you have rx8 porting templates?

thank you vins lee


I don't recommend porting the RX8 engine. It is cheaper to p-port and
you get far more power.

Paul, I'm new to all of this, although I've been interested in rotary
engines since they came out. What is a P-port?

In the youtube video demonstration of a tandem Autogyro. I believe
the Mazda 12a is the power plant. Could you also have used the 13b .
I am assuming the power  requirement is between 100- 110 hp

Regards Zahid


Yes. The power could be much higher. Perhaps as much as 150 HP.

    12b spare parts are fully discontinued, while some 13b still remain.
