b16 turbo question.

well i was thinking of going turbo on my b16A2 teggy and well was wondering if i can boost it on its stock form. I mean i dont have to drop the compression to boost and if not whats the safest i can boost on. My next question is that my b16 head has some headwork done to it wich is…port and polish with a competition 5 angle valve job TI valvs and retainers and i think i have some stage 2 vtec cams killers well can i keep my cams or i have to go back to my stock ones?
