D16y7 with VTEC Head

By PopKorn689
- Sun Nov 28, 2010 11:00 pm #224960 Hey guys so far in the past month this website has helped me out tons with D series info and I am going to come to you for more help. A buddy just got a 97 DX Hatch and we are thinking of putting the y8 head on it but were wondering what kind of compression and power would be made with this. I'll keep searching for the time being but if anyone knows let me know. Thanks.

Also something about the y8 head gasket being thinner? What's up with that? Again still searching so I'll post what I find and see what ya'll think.

- Tue Nov 30, 2010 1:28 am #225119 I love that page! Thanks a ton! According to that calculator I'll be looking at 9.9:1 Compression with a y8 head on a y7 bottom and if I can locate this mythological 2 layer y8 head gasket it'll be around 10.25:1!!! :woot:

that is correct, AJ.
i don't recommend doing this.
just mill the head if you want a noticeable compression bump.
