I posted on this recently. The poster who said it had been done was relying on someone else's word that it had been done.
The 350Z's tranny won't fit. I did extensive measurements and comparisons trying to see how it could be made to work, and nothing lines up from the bell housing to the tranny mount to the gearshift. Even the speed sensor's different and doesn't interface with our ECU's. The only part of it that mates with our cars is the input shaft and splines. And if you were thinking about making adapters, good luck to you.
