The 42-year-old former grand prix driver has been racing in sportscars since the end of his Formula 1 career in 2002 and won the GT2 class of the American Le Mans Series in 2007.
He has had a seat fitting with Michael Waltrip Racing and expects to test one of the team's Toyota Camry Cup cars at an undisclosed venue at some point in November.
"It will be great to get to test a NASCAR at last," Salo told this week's AUTOSPORT magazine. "After two years of trying, I finally met the person who could make it happen. Racing sportscars in the US has definitely helped.
"My hope next year is that I can do some races in Nationwide, maybe even a full season - but I understand that I may have to raise some money to make it happen."
