Does anyone have any thoughts on the durability of an all aluminum rotary.
Why hasn't Mazda done it?  Cost or heat efficiency?

Has anyone used the Racing Beat PP housings? I don't feel comfortable
reworking a housing.

PP [rotor housing] for non-turbo

$837.00

PP [rotor housing] for turbo

What about building up a complete aluminum engine using these parts?
Sure they are expensive, but you are still looking at probably less than
$8K for an engine, low by airplane standards. They have a part for the
20B as well.

Cost probably. The competition is stiffer now and they need an all aluminum
3 rotor in the RX8. Durability should be about the same as the rotor housing
with steel lined aluminum end housings.
