I got toasted last night by someone running a 'mini-me' setup. the dude said his y7 block + y8 head yields more torque in higher revs than my stock y8 because of the higher compression ratio.

from what I understand, one way to increase compression in an engine is to bore the cylinder heads and get oversized pistons. is this the only route? and if it is, what specifically is involved? does this also increase displacement?

any help/info/experiences would be appreciated.. lates!!!

 

I think you mean bore the cylinder sleeves, not head. Why dont you get a VTEC head(D16Y8 head), it shouldn't be too expensive at all.

Ways to increase compression is to get higher compression pistons, or a thinner head gasket.

 

You can mill your current head. Reducing the effective size of the combustion chambers, thus upping compression...

he has a d16y8 so he already has a vtec head....You could mill your head to get a higher CR.
