Better performance on streetported na.. s4 intake or s5 intake w/vdi ?
Ive been reading on this, still isnt really clarified well as to whats better for a streeported engijne.... mine is getting streetported from rotary resurrection....
Was wondering why s5 intake is good for stock ports but not streetported ?? thought s5 is higher flow so is better for powerband 4000-7000rpms .
The s4 from what i saw is more for lower rpm 5000-6000rpm
im hoping to get 170+ rwhp out of my car, what would be better , s5 intake or s4 intake ???
this thread on stock ports sure shows the difference....

i also saw some people port the s4 intake manifold , but ive heard alot of mixed opinons about how much of a difference you get from doing it

I've pulled 166rwhp out of a stock port S5. So your goals should not be difficult with either.
