Mark Curley sent me some stuff from the Detroit auto show
on the RX8. This is from a press release on the RX8 engine.

The intake ports are indeed 30% larger.
They claim twice the exhaust port area.
The exhaust ports open later and open more gradually.
This should quiet the engine a bit and and improve the BSFC.

More spark energy and finer fuel injector atomization.

Mazda also claims lean burn under high load conditions.
