Bet its mostly Suby. 170 hp vs 117 hp. Probably the same price. Only reason to get the Audi/vw is to get the 0 mile crate engine. Think I'd find a 2.5 L Suby with 30,000 miles or less and use that. If I ever do another IM it will be an outlaw Suby speedy probably with a 4-speed 3.44. Kind of enjoying my conv D right now.
