turbocharging a fully built B20v

i have a 96 coupe with a fully built b20v(GSR head) running a 12:1 compression. originally its built for all motor( aries pistons, buddy club st.4 cams, milled, p&p, etc..). I wanna turbo it with this set up, but i need to know if its safe and howmuch psi i have to run. thanx for your help.

the 12:1 compression and thinner b20 sleeves should tell you something in a search.

buddy club cams are a no go with boost.

rods and pistons does not = "fully built"

Well you said yourself its "built for NA" so why turbo it? You need to drop that compression to 9.0 at least, new cams, new bottom end, etc.
