i was wondering whats the difference between 70mm and 75mm besides the size... and what will fit a 96 gsr

im deciding between SKUNK2, JG EDELBROCK, or BBK.. has anyone heard of BBK?

and one more question... lets say i get a skunk2 throttle body, and then i wanted to get an intake manifold, would i have to match the brands (get a skunk2 intake manifold) or could i mix them up?
