How is your ground between the engine and the battery?
So I just did a little research and found out that the 2001 Pathfinder had a 5sp manual 2wd option. About a dozen assumptions aside, that probably means that there's a VQ to FS5W40A bellhousing out there. So there's an option to VQ a car and use the proven 300ZX transmission.
Also, 2009 G37 MT Convertibles have 3.916 differentials (open) stock, which would be a lot better option for 350Z/G35 guys than paying $500 for a gearset and another $500 for someone to install it. It should just drop in.
