AS far as turbos goes it not going to happen
the intake and exhaust ports are inches away from each other as peripheral ports and cooling on that scale can not be done, But supercharging maybe. The higher rpms of the rx-8 still do not make up for the RX-7 turbo system.

My how stupid and foolish those idiot Mazda guys are, I mean who do they think they are anyway? What the hell would MAZDA know about putting a turbo on a rotary? Nothing I'm sure!
Then there's those hopeless asses at Mazdaspeed putting together a turbo charged challange car. Be sure to tell them it's a waste.
And Paul Yaw? Yawpower? He's got to be the stupidest son of a bitch on the planet for putting together a supercharged renisis for competition. I mean we all know Paul Yaw has never put together anything decent in his whole life, all his work on rotary engines just SUCKS ***!
You tell em!

For all those people who have studied turbo thoery and have actually put them on cars put your hands in the air 
Also put you hands in the air if you know or can caluculate heat transfer,thermodynamics, of casted steel taking.
put your hands up in the air if you have a ruler can measure between the rensis intake ans exhast ports
After you have calucalted all these things and still say that a turbo is a go options as far as a performance feature that means you are not an engineer or engine rebuilder.
MAZDA if they ever plan to produce a turbo model of the engine will more then likely use a big old cast iron exhaust manifold increasing tha amount of heat that the intake port will see. A tubular exhuast is a better option but
in mass production is expensive and doesn`t last as long as a full steel.
The supercharged option it the best due to the relativly recent growth and inprovement in centrifical supercharger set ups. You don`t have any of the heat build up with the turbo exhaust manifold, and lower compression rotors will also reduce emission even further during ideal.
I have much respect of Paul and for the work that he has done in the rotary engine community in the states. I also think that the renisis is more of an eco engine then pure performance.

It's very simple.
The Renesis is only an attempt to prove to the guys sitting in the big chairs at Ford corporate that the rotary in fact is a viable engine in the US market. If they can manage to back that up with some impressive sales numbers. Then maybe just maybe Ford won't keep Mazda from making another rotary powered car.
Hopefully one day Mazda will get back to making what would have (hopefully will be) the most uniquely powered "Super" car ever put into production.. The Rx-7
I would even settle for a turbocharged/rotary powered MX-5
I would suggest taht if you ever want to see any other mazdas running unedr rotary power you get out there and buy a rx-8 even if it is not as fast as you might have hoped it would be. You do realize that it's not easy to beat a Fd
