370z Forced Induction for Noobs...
Forced Induction Finished Builds
2 Good threads to start with. Greddy is no longer manufactured so you can cross that off the list. For Twin setups, you are looking at AAM or F.I. Boosted Performance has a very popular single setup as well. If your Nismo is AT, you will need to upgrade the transmission as well as the 7AT is not built for much more torque than stock.
