I am going to turbo my car, most ppl go the easier route with the s/c. If you get with the company making your turbo kit, you can get thru everything with them and they will help choose the correct kit for, thus pretty much eliminating lag. smaller turbo will have less lag but prod. less power, and a larger has more lag with more power, but either way, properly set up both ways it will prod. more than enough power to take on the superchargers. the s/c may get the jump but once the turbo hits, it will be all over...
