Im building a ld9.t and im planning going over 16psi of boost.
Whats the max boost that this stock intake mani could hold?
Do you guys recomend to change anything from the head? Its currently virgin..

really no limit on the stock intake manifold.
agree with John, I've never heard of anyone blowing out the stock manifold......... although at a certain point its got to become a HP restriction.
