Contact Iron Chef if you're dead set on importing a turbo car (there are a few turbo imports on sale locally).
I don't recomment buying a turbo car as your first car. You're better off getting an N/A (R31 wooo) until you get a decent amount of mileage under you (i.e. experience). Plus it will be cheaper for you and you get more time to save for a better condition turbo car later on.
On a side note. The R31 Ti came with speed sensitive auto locking feature, think it locks once you go into double digit speeds. Driver's door should unlock when you pull the lever though.
