Aside from it being a different year and a sedan, it has the same motor and all of the parts I put into my car, fit into a 2000 Si. What sets an Si apart from a regular coupe? The motor, and some slight interior adjustments. I have the motor, just not 2 doors or the interior difference. Plus my car has walked Si's before so i should call it an Super-Si :]How do you figure?
