FC is a chassis code. Every car has one.

RX7 wise, FB is a first gen RX7, FC is a second gen, FD is a third gen.

RB I would mean Racing Beat. RE is re amemiya. MS is mazdaspeed.

Than you have engine components, AFM = air flow meter, CAS = crank angle sensor, MAP = manifold absolute presure sensor, OMP = oil metering pump

I am not sure what other ones there are that really mean anything

T2 = Turbo II model rx7. Available 87 to 91 in USA.

MAF = sometimes used instead of AFM, stands for Mass Air Flow Meter

SA/SB are sometimes referred to as well, these are just earlier chassis codes of the first gen(FB) cars.

FCD = Fuel cut Defender

LSD = Limited Slip Differential

TB = Throttle Body

UIM = Upper intake manifold

LIM = Lower intake manifold

ITB = Individual Throttle Bodies

That should get you started floating around the forum world, feel free to post any more you come across and don't understand....
