will a lexus sc400 maf work on a fc? it looks like it would flow a heck of alot better but i didnt know if the voltages were close enough to where it could be swapped on. . . any help would be greatly appreciated.

Of course not. It's a completely different car with a totally different EFI system.

And the AFM is not much of a restriction on most RX-7s.

on these cars exhaust restriction plays a much bigger roll in performance than intake restriction, relatively speaking.

Bwwhaaaaa? The afm's are interchangeable from s4 to s5? What are the drawbacks in a swap?

They cannot be swapped without some trickery, and even when done, it throws the fuel curve off.
