Glad to see that you are going to go with a JDM theme on this. PBM make some really good shit, they are like 20 minutes from my place, and they have a pretty down to earth shop. Have you started premixing yet?
Sounds like a plan mane. Don't eliminate the intake bridge when porting unless you want to balance the eccentric shaft and rotors and shoot for a 10k rpm limit, that much intake port is useless on a street driven car without a huge budger. It's really useless on a street driven car, a mild streetport on 1-2 intake, large streetport on 3-4 exhaust and maybe the largest port allowable without removing the bridge on intake 5-6. My buddy caleb had that setup when we were in high school, it retained it's good manners on the street, and screamed up to 9k. The engine builders said it was good up to 215rwhp all motor NA, and would be a monster to boost even with the higher comp s5 6 port rotors. A cheap alternative to lower the compression if you want a bit safer time boosting, look into the NA s4 rotors, and swap on some good seals. Hope that helps a bit. Oh yeah, most of the TII stuff is a bolt on affair except the IM, but if you go FMIC and standalone, or good piggyback it shouldn't be a problem. In all if you get it all done at a good shop with you helping out a setup that can hold 400 at the crank should be sub $4000 including a cooling system overhaul and supporting mods like injectors.

If you have questions, always check these websites. If you think you have a strange problem, those guys have had the same problem 100 times over. Just put on your flame suit when asking questions.
Oh yeah, welcome to the rotard side.
Remember to pay once and cry once. Poorly made engine components and a failure to adhere to the strict maintenence requirements of the 7 is the main downfall of the rotary engine.
