The RX8 rotors are 10.0:1 but they need to be machined to work in a older engine. I know the apex seals are different and I believe the corner seals will cause you issues. It is just easier to run the 9.7:1 S5 N/A rotors.
here is the ratios and weights, I was off a bit.

You can make good power with the N/A rotors in a boosted engine (which is why I'm doing it), but the chances of detonation are higher due to the higher compression. I'm fixing this with e85 but a lot of people probably aren't willing to do that. I'm only doing it this way because I'm starting with a N/A platform. If I had my druthers it's just easier to start with a TII block.
