First off again I have a 1993 SSEi. I wanted to know if I could swap the series 1 with a series 2, and if can what is all needed. Also is it a good idea? Will I lose horses/gain? Lose gas mileage/gain? Also what are the major differences? My big concern is that whole hydrolock im hearing about. That an having to use Premium sucks ( is that only with the super charged models?). Also at what milage should the supercharger oil be changed? I'm new to the super charged scene.
