Answer
All this depends on which year you where looking at and do you mean to import one or one already here.to import one will depends on which state your in as each is different some require changes to the car whilst some need only a very few changes whilst some states are a no you cant have one.if your going to buy one over here or import on it maybe worth looking at the gts,gts-t,gt,gtt versions also as the gtr is dear anywhere in the world whilst the non turbo and single turbo versions offer rwd fun and all are tuneable,with the single turbo versions be able to mod a little cost to gtr bhp but all these models are cheaper on your budget at the start. again which year from the r32,r33,r34 and you even go down in years to the fifties in skylines.price wise will again depend on where you are getting it from and can vary so much,http://www.nhtsa.dot.gov/cars/rules/import/http://www.nhtsa.dot.gov/cars/rules/import/faq%20site/pages/page10.htmlhttp://www.nhtsa.dot.gov/cars/rules/import/faq%20site/pages/page10.htmlhttp://www.nhtsa.dot.gov/cars/rules/import/graymarket_ri_list010807.htmhttp://www.edmunds.com/insideline/do/features/articleid=105699http://jdmstock.drifttuners.com/?id=usa#dochttp://www.azines.com/linked_cars.asp?pid=55http://jdmstock.drifttuners.com/http://www.pistonheads.com/sales/list.asp?s=153if you are wanting the new gt-r then cool,but as there new they will be expensive compared to an older model,and the older ones are great fun hence them already being legends across the globe.the new model will come as lhd also,but as said yes they look great and are new but the older ones are a car which gives you a huge smirk each time you sit in the drivers seat.
