depends on the turbo setup too... if its a sts a 38mm waste gate would be ok. im gonna be running 15lbs on a 383 and have a 46mm that RealQuick said would be better than the smaller stuff he usually used. BUT my kit is a lil different than others. i would say 38-40mm waste gate.

for the BOV i have a tial 50mm it should do the job just fine w/tons of room to spair. i mainly got it b/c of the design.
