yes you can import it. I've imported a few cars. The biggest stickler is the ownership but you don't need it but the border agents are senseless sometimes.
First i suggest you use a broker as you will need a us itn to export it. The broker can handle everything.
You need a bill of sale and proof it's a competition vehicle. Us customs needs to stamp it then canadian customs needs that paper and proof it will be used for competition here only.
I got a letter from casc and a bill of sale and that was good enough.
I paid these guys $100 well worth it.
