Not to sure, but the comparison should be interesting. While the FRS is about 300 kg lighter than the 350Z so in theory the power to weight should balance out. But considering the FRS is FWD I think it will always loose out acceleration from a standing start. Rolling might be a different matter.

The 350Z extra power should help it out for top speed. But the focus is supposedly the better handler.

Personally I prefer the 350Z over the FRS
