2. Vacuum distribution box is tested, quite good.
3. For injector upgrading, i am looking for new solution with AIC (instead of replacing bigger injector and Power Commander V)

Good work!
Don't do AIC, that's 1980s technology! You also need to program new ignition map. Reduce full-throttle ignition-advance by 5-10 degrees while leaving idle and partial-throttle/low-RPM ignition stock. Using 3D mapping of ignition (load X RPM) is much more accurate than factory 2D map.
Get replacement aftermarket programmable EFI system. Look up greg737's excellent EFI conversions. Use EFI system from Accel DFI, Austronic, Electromotive TEC, Haltech, LinkECU, Megasquirt, MoTeC, SDSefi, Wolfe 3D, etc
Megasquirt is best value EFI system. Controls both fuel and ignition with 3D-mapping. Plenty of on-line support from large installed base of users. Someone probably already has maps for Ninja 250+turbo and all you need to do is download it.

Some sites with great info and support on Megasquirt:

I've blown up plenty of turbo engines by trying to keep factory EFI system and use piggyback systems on top. Very wasteful of time and money. Now my first upgrade is programmable EFI system, even on factory engine with no mods. Good for +10% increase in power immediately and smoother running with optimized maps.
Remember: cheap/powerful/reliable. Pick any two, but you can't have all three.
