IMO if your building the motor then ditch the SC idea and go for twins, built motor is overkill for a basic S/C build. Ditch the UTEC & go uprev or syvecs.
AAM basic kit is good enough for the figures your aiming for, I used it in my build. Cosworth fuel rails are not needed at these power levels but if you want rails then go for one of the higher spec AAM kits.
Don't forget gauges - Oil temp, Boost & fuel pressure at a minimum along with a wideband.
Have a look over on my350z.com at the Vortech bible also, I spent weeks reading that before my build
