Get the mazdatrix 6-port streetport templates, they are tried and true, I'm unsure of the power gains, but I think they will get you to your goal, while being streetable.

Mazdatrix says to go with the TII rotor housings because you can port the exhaust easier, while it's easier, it's not required, you can drill the pins out on the exhaust diffuser and pull it out and port the exhaust and the put it back in with new pins. Check out mazdatrix's website, they go into major detail.
