It would appear that the 300ZX and everything else from the 90s has been dropped from the Nismo catalog, the brochure on the Nissan USA website doesn't even cover the 350Z anymore. The one on the Nismo.co.jp website still has the old parts listed but it doesn't give off the impression of a website that's updated much. If one were inclined to call on enough dealers and parts stores it's probably still possible to put together a full set, though anyone so inclined should act quickly.
