 Is the 16b all aluminum?  If so what do these engine cores fetch on
 the used market?  What do you think a single rotor 16b variant would
 weigh?

 Matt Naiva

 Yes all aluminum except for the rotors and e-shaft.

 It is not in production  yet.
 They are still doing R & D on it.
 Mazda now claims the prototype burns less fuel than
 their excellent piston engines per HP generated.

 That is an earth shaking event.

Lets hope they obsolete the piston engine and make several million a
year of the next gen rotary and offer it in all their vehicles :-).
What does the RX8 use? 13B?

Matt Naiva


The RX8 uses redesigned end housings and a modified 13B rotor housing.

The exhaust ports are changed from peripheral to side exhaust.

This reduced the un burned hydrocarbons in the exhaust
and further improved the idle. Other than that it is
basically the same as the 13B.
