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

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

Sorry,It is my fault that in my previous email I have not provided enough information to get the answer I a looking for.

My end goal is to have a mazda rotary power plant for my parsons tandem and the project completed in the next 12 months.
(saving as much money as  possible).
So far I have the drawings of  parsons tandem (attached).

I also have in my possession Bruce Turrentine's video on overhauling the 13b mazda roatry engine.
Having seen it I believe I can overhaul the Mazda 13b  engine.( not sure about the 12a I do not have knowledge of the differences between the two)

The reason I ask the question is because I am starting a project and it seems me to be that
the 13b engine is easier to get hold of than 12a and I have video showing on how to overhaul it.

I am currently waiting forthe aviator's guide to rotary conversion by Tracy Cook to get a better idea of what is involved in the conversion after the rebuild of engine.

I know there is a lot of documentation on the website , but for me I need a step by step guide.

I am looking for guidance for my project,  at the moment  I am looking for  a recommendation on whether  I should use the 12a  as per video or should I use 13b for my parsons tandem.

regards,

Zahid

use the 13B.
