well there are many things needed, but it is possible. swapping doors(they need door bars) rear 3rd light, amber signals(and enough of them) US cluster, but those are some of the more basic things. There are companies that can import a car for you and get it registered, but it can cost a lot. I plan on making mine US legal incase I decide to sell when I buy a new house. Good luck, there is info out there, but sometime you have to make some phone calls. I know of at least a dozen tourings in the US, and not much more than that in Canada.
