Ill just chime in even tho Im a few days late and way more than a dollar short...
RHD is no big deal, at least in Arizona. I know a guy down there who has an RB20DET swapped S13 and he also converted it to RHD (dont ask why, wayyyyyy too much time on his hands) anyway, its all registered and legal and crap. Im DAMN sure ND's registration and driving laws are a wee bit more relaxed than AZ's, so you should be fine. I hope to see you next saturday at the autoX, that should be PIMP-tastic. Ive seen a few GT-R's (as well as an RB26DETT swapped into a GTS base model) skylines before and have loved every one of them!
