In a week or two, head out to some of the local speed shops, and ask around about getting a b16 swap. If a place says "yeah, we got one in the back in stock" or "I can have you one in 2 days," go check it out. Maybe you'll find your vin # on it. Thats when you start asking some serious questions, and/or threaten to call the cops unless they tell you where they got it. Give it a shot...it can't hurt.
