Yeah, stay where you're at. If you think a simple zetec-already-been-engineered-to-work swap is too much trouble, you have much enlightenment coming in the future...........your idea of 'a small performance build' is going to need some serious adjustment to agree with the real world. Giving away modern 4 valve tech to old school 2 valve low HP tech is ridiculous. The supercharger will only make that difference lightyears worse.
Of course, some people ENJOY banging their heads into the wall.
