Ak, bought and read a REALLY GOOD book on rotaries from amazon (Street Rotary HP1549: How to Build Maximum Horsepower & Reliability into Mazda's 12a, 13b & Renesis Engines (Paperback)) and have a few more questions specifically regarding porting the 6-port.

I have only been able to find a "street-port" template for the 6-port. Is it feasible to do a half bridge of sorts on the 6-port? i.e. retain the street port on the primaries and secondaries but put a bridge on the aux ports? Would this help any on an N/A motor retaining the aux port sleeves and actuations? Also, what sort of effect would this have on the powerband? broaden the top end more? and a related question would be, when running a ported motor like this and a standalone like MS, where would i have to set the rev limit as a ballpark number? 8000?

If the above is NOT a good idea, what are some other things that can be done for power improvements on a 6-port specifically regarding porting?

Keep in mind, this is intended to me a mid N/A build with the eventual addition of a mild boost setup on S4/S5 hybrid N/A motor...
