Re: D16Y7 and D16Y8 bottom end...same?? (thinkbrianthink)
^^higher compression due to vtec valve train, and thinner headgasket
d16y7 and d16y8 both have the same block, and all the internals are the same, it's just the heads that are different...but the y8 head flows better than the y7...

Re: D16Y7 and D16Y8 bottom end...same?? (4potnick)
Some wrong info going around here.
The Y7 head yeilds 0.2 less compression than the Y8 head due to a large combustion chamber (lower CR)
Y7 head's combustion chamber= 34.6cc CR= 9.4:1
Y8 head's combustion chamber= 32.8cc CR= 9.6:1
Same pistons is memory serves...
The Y8 also comes with a super thin stock H/G.
