T2 center iron in an s4 engine ?
I was watching the RA overall dvd and the guy said that substituting a t2 center iron into an NA 13b would basically be like a slight port without having to actually do a port. As i already have to replace my center iron so is it worth it I haven’t really seen anything else about it.

the answer is an it depends.
if you have an S4 both ports open at 32 and the NA closes at 40, and the turbo closes at 50, so that is a little improvement
but
the S5 has the same closing times as the S4, but the S5 T2 opens later (45 vs 32), so who knows what that would do?
