Starting points:
Forced Induction for Noobs...
370z Forced Induction for Noobs...
Forced Induction Finished Builds
Then go here through a few individual threads in the FI section and find out what you are looking doing it.
Tracking, street, show, etc.
What is your budget?
Do you have any current mods that can be used or have to be removed?
To start you off, there is not really a "piece together" type of setup for the 370z group. You really buy the full kit with a couple options, tuner or turn key from different companies.Tuner is the whole kit minus fuel and tuning while a turn key includes the missing items.
