Not sure if Mazda plans on bringing back the twin turbo version of the engine, but I"d have to think that you'd get 320 out of it with twin turbos blowin in to it. Problem is the related seal issues that come with that extra air blowin through there.

 

Nice Job
I like the RX-8's, they're very sharp. And afterall they are owned by FoMoCo

 

Well, simple fact is that hp sells cars, torque wins races.

These produce good hp for their size, but the torque produced is low. RX8 vs '05 Stang is a no brainer win for the Stang.
