DC2 breathing>EK9??

[93whitehatch]

im just wondering if and ITR breathing (throttle body, intake manifold) better than the CTR? if it is then suppose if switching to ITR breathing system would the B16B motor see any gains?

They have the same intake manifold, only the TB is different with the TB being slightly larger on the 98spec DC its 62mm vs the EK9 60mm. As far as gains probably 1-2whp

Should you change to the dc2 tb would you not need to port the ek9 manifold to mat h the bigger bore ?

And the header is better, isn't it? I thought both or only the 98 spec header was better than the EK9 header.

98 spec header is excellent (if not a little heavy)
