TitaniumTT's I hope I make it to DGRR '09 Build

You can say that again!! I would love to see that (0.91L and 38 BTDC timing FTW)

Do you intend to take the Twin Turbo out and put it in the FD and then build the 6-port for the '88? If so, I would hope that most of the beautiful intercooler work would port over to the FD (although I think you like doing that kind of thing anyway).

I won't know until I see what I get for power from an E8 (Yukon Coil packs) and 9.5:1 rotors. According to my calculations:
Actual Power: 216 WHp @ 7500 rpm and 160 Wlb-ft @ 6100 rpm
Power based on VE with 8.2:1 rotors (if ignition is really an issue and it isn't something else) = 248 WHp @ 8500 rpm and 176 Wlb-ft@7700 rpm
Power based on no VE change going to 9.5:1 rotors (11% increase) = 277 WHp @8500 rpm and 195 Wlb-ft @ 7700 rpm
Power based on lower dynamic head loss from shorter-runner custom intake manifold (Shifting power band 1000 rpm) = 195 Wlb-ft@ 8500 rpm = 315 WHp @ 8500 rpm

Bear in mind that none of these calculations require VE in excess of 108%, nor do they require revving in excess of 9,000 rpm, so they should be completely feasible. Of course, this relies on piston-engine rules of thumb holding true. Namely:
Torque is a direct function of VE
Compression ratio improves performance by about 8% per full number in the 9:1 range
Intake runner loss calculations (relying on relative surface smoothness, number of bends and length) are similar for a rotary.

We will find out in the spring (if I ever get the high compression rotors in the engine and an E8 for in the car).

(I am expecting the streetport to exceed my P-port power, actually) I am going to build the P-port using Renesis housings so that I can locate my exhaust port differently.
