2001 1.8t intake manifold
 

so I have a 2001 1.8t VW passant. I just got a 3" downpipe and 2 1/2" exhaust the rest of the way back. And I have a performance chip. It boost 16psi. And I was wondering if I buy an intake manifold well it give me any HP or a waste of money right now??? Please help. I plan on. Buying a gt28ts turn o kit for it and stuff in a couple of months so I was wondering if I should just save that moneyfor the turn o kit and then buy the manifold later or would manifold help me out now and even more once turbos on????
Thanks
