We don't get them because Nissan didn't want us to have them, simple as that. However, for all you fanboy's out there, Nissan will have the New GT-R over here, as I'm sure you know, in '08. There was one cool 200SX, and that was the '84(?) through '88 one, which was a direct import of the Japanese Nissan Gazelle, aka the S12 Silvia. Big engine was the 3.2litre(I think) V6, however, it was also available with the CA18.
Cheers,
Matt.
