Ignore what i said about 10 8 10 boost, thats for 3rd gen rx7's with sequential turbos. Didn't think about it being a 2nd gen. I wouldn't worry too much about vacuum provided you have good compression numbers. But stock ports usually pull over 16". My large street port pulls around 15" at 1000 rpm.
