Spend some time reading these:
Forced Induction Finished Builds
370z Forced Induction for Noobs...
On that note, things to consider.
-Oil cooler is required
-Custom tune is required (this will also allow for fan speed adjustment)
-Clutch/flywheel/csc will need to replaced at some point, can do it now to maybe cut down on some labor cost
-Gauges, you will need to monitor the car beyond the normal gauges. Preferably boost, AF ratio, and possibly oil pressure. Many options, can replace the 3 factory gauges, run a carPC or obd2 reader with extra sensor.
