datsun is what nissan of japan named nissan of america when they released the 510 and the later Z's. the reason for this is because nissan of america wanted to go road racing and compete against bmw and alfa romeo. nissan of japan had no faith and figured that the 510 is no match for its european rivals. so in order to save their name from potential himulation, they changed the name to datsun. and as for 200sx. the 200sx is what the austrailians and the europeans call the silvia. nissan has a way of naming cars from their displacement size. since hte euro spec silvia also has a SR20DET and a SR is a 2.0 liter engine. so they call it a 200sx. just like how we got 2 different 200sx's in the states. one is from a S12 chassis and the others are from the B14 sentras with the SR motor.
