does anybody feel a big difference between the d16y7 intake manifold and the d16y8 manifold on a d16y7 head?

does anybody feel a big difference between the y8 headers on a y7 head v/v y7 on y7?


any difference at 4000 and up rpm... because i might just put an intake on it

d series ftw...too broke to smash and waste gas...damn it

Yes, the y8 manifold has better flow than the y7 does. As far as actual HP goes, i wouldnt say it makes a significant difference on paper, but anything is better than a downdraft manifold.

i went from y7 to y8, i think the y8 defn has a little more kick to it. Nothing jaw
dropping though.
