anyone know the stock CR of a Y7 bottom end?

 

it depends on the top, the stock bottom end with no head has no compression

do you know what compression ratio is?

incidentally the y7 engine has a cr of 9.4

 

well, with a y8 head, do you think it would raise or lower the compression?

 

not enough to matter

a y8 head, would hardly change the cr, very true. but as far as HP, the vtec would help much more than the change in compresson

 

The compression is raised to around 9.8 or 9.9 when using the y8 headgasket as compared to the 9.6 of a stock y8.

 

do you think this would be a decent boostable setup?

 

Boost it as it is without the headswap.
