TOYSUP is right. It would be more cost effective to save the money and just buy a TT than to swap the engine, ecu, ect...
Even if you are intrested in the SE because it is a hartop (hardtop TTs are difficult to find), this would probably not be a good idea (financially).
To my knowledge, all of the SE models were autos and the auto tranny on the NA models is significantly weaker than the auto on the TT. Pretty doubtful that it would hold up to the power level of even the smallest Single turbo.
Soooo... unless you planned to change the engine, tranny, brakes, ecu, etc....this would not be the best course of action. In the long run, it will probably cost you *ALOT* more.
