Smyrna388Z posted a topic in DrivetrainBy chance has anyone on this site changed the gear ratio of a 1989-1996 Q45 differential? My project is to change the 3.54 gears in a Q45 differential to the 4.08 gears from a NA 300ZX. The Q45 differential is currently installed behind an LT1 and 700r4 transmission in a 1976 280Z. Thank you to anyone who may be able to give me some information.
