check out both because there's different stuff at each for some reason. the museum has some really nice pics and info (NOT in english), check out the S13 sr20 redtop pic. there's also scans of the many brochures nissan printed out, (it's under catalogs, might be hard to find). under the history link there's more pics and info (NOT in english).
