Have you asked the seller about this yet? I swaped my car and I never got a rebuild title. But I also live in wisconsin, it never even crossed my mind to think of getting one. Were you aware that it had a b16a3 when you bought it, or were you under the impression that it was the stock motor? Never the less the first thing you need to do is confront the seller of the car. If he does not know anything about cars, then maybe he did not even know what motor it had in it. And you definately should have checked out what was under the hood before you bought the car.
