Thread: s3 intake/ s4 exhaust set up

air going in needs to go out, why would you only put a larger cam on one side?

we were talking about using two big cams with very minor differences on intake and exhaust.

Just use both, they're only slightly different and should deliver a nice performance increase (especially if you combine it with some tuning time on a dyno). If it's really that bad (which it won't be), you could always remove one or both quite easily.

I ran this combo in my old n/a nx2k. it's definitely an upgrade to run both according to the butt dyno.
