Forum:KB:what makes a TIE

Hey guys! I just wonder, what have to be done to make starfighter a twin ion engine? I mean Eta-2 got 2 ion engines but it isn't a TIE, and since X-wing got 4 ion engines, wouldn't that make the X-wing QIE(Quad Ion engine)? Wait, bad example, X-wing got fusion engines right? And while we are talking about thrusters, correct me if I am wrong, but sublight flame color don't matter right? (A-wing got red flame, Delta-7 got yellow, but A-wing's faster...)
