Here is the other thing s/c work with higher compression engines wheras turbos need lower compression which would mean I would have to change the pistons in order to achieve a lower compression ratio in my engine.
INCORRECT. Because the S/C is crank driven it will not reach full boost until a certain RPM,, you don't just sit a supercharge on the intake and expect it to instantly make boost. Ask anyone with a supercharger (plenty of duratec owners on here) I believe the vortech for the duratec doesn't reach full boost until over 3k rpm. You can easily setup a turbo to reach full boost at the same place a s/c does or before. Not all turbos have lag, they have something else, can't remember what it's called, which is the point before they reach full boost but it is NOT LAG. A small turbo with a good setup will not have any lag. And as low compression is good for s/c AND turbo. High compression is good for n/a and nitrous... Why is this even being discussed,, you're not even gonna do it anyways.
