Hello Mr. Lamar,

I have an RX8 4 port engine in a competition car.
Is it possible to use Mazdatrix P-Port rotor housing from an RX 7
in my RX-8 engine?

Will it be good?

Respectfully, Michal

Yes.  You can use RX7 P-port rotor housings in your RX8
engine. You will then have six exhaust ports which is very good.

I would not use all six ports for the intake however because
I think you would get more power with just the two p-ports.

It is easy to try all six intake ports so I would try that as well.
