Actually, the trans has as much to do with clutch selection as the flywheel. The clutch disc itself has to mate to the transmission input shaft (which NA and T2 have a different spline count). Of the same token, flywheel diameter also factors in clutch disk diameter and pressure plate diameter.
When I used to havea Starion/Conquest I used to keep up with their forum as well, and on it there was a guy that specialized in making bellhousing adapters for various engine swaps and transmission swaps. He would always state that when selecting a clutch you would buy for the transmission (coincidentally the 88/89 model year starion/conquests used the same diameter flywheel as the turbo rx7's)
But OP has stated hes using a S5 turbo flywheel (on a S5 NA) and mating the S4 turbo trans to it (which is all well and good as S4/S5 trannies are interchangeable, just the trans mounts differentiate).
So he needs a 13BT clutch set of either S4 or S5 origin, which series he chooses is probably up to the wallet if there is a pricing difference

are the starters different? Since the starter bolts to the transmission wouldn't it effect the engagement if you mix flywheel and transmission? i.e an s4 starter wouldn't reach an s5 flywheel because of the 10mm difference in diameter.

turbo starters are interchangeable as are the non turbo if you keep it either boosted or naturally aspirated being that the non turbo starters have the solenoid on the opposite side of the starter.
the non turbo automatic starters are the exception and can be used as a high torque alternative for turbo motors.
basically there is non problem using a s5 TII starter on a s4 TII and vice versa.
