BloodReign, I've got the 80cc ports on mine.
Theoretically, I'm not sure if it is good bad or indifferent to have larger exhaust ports on a turbo car. I think it'd be good because it improves flow, which should mean quicker evacuation of the exhaust from the cylinder and hence less reversion. And, I can't see why the decreased exhaust velocity from the ports would hurt performance. After all, I don't think turbocharged engines take advantage of exhaust scavenging the way n/a and blower engines do. It's just all speculation on my part, though.
