Alright so I have a question. What are the performance differences between the 04 -06 RX8s and the R3? (Excluding basic driving differences and cosmetics) would I be correct in sayign that the R3 just has upgraded exhaust, intake, and suspension?

Secondly, I was wondering a lot about porting. Basically here is a rundown of questions. Feel free to add more answers in because though I know the basic concept (the diff b/t street, race, and bridge port) I dont really know to much more. So here goes:
1) How much would a street/race port cost?
2) I believe street ports are street legal and race, bridge ports are not. Is that correct?
3) Where would I have to go to get this done? Would a tuner who knows a lot about rotories be able to do this, or would I have to go to rotory engine rebuilder?
4) I understand that porting makes the car louder, less fuel efficient, and more powerful. Would I be correct in saying that the increased flow or air would create less wear on the apex seals? (less pressure on the third stroke?)

Thanks for your time guys
