Question about silvias'

Hello every one i have a question about the silvias' i'm wondering if the silvia S13, S14, S15 are sold here in the states under a different names?

thanks all :)

S13 and S14 - Kinda. Nissan bastardized them into the USDM 240SXs. The S13 Silvia got the 180SX front end (pop-up lights) and the KA24.. motor, and the S14 looked pretty much the same, but again, it got the KA24.

S15 - No.

Alright, thank you Jay.
