since nobody else checked in yet, max half point drop in CR, not familiar with d series.

Re: compression ratio question (Hella_JDM)
 

i think you can figure this out by yourself...

Compression ratio = maximum cylinder volume / minimum cylinder volume

OR

compression ratio = (cylinder volume + chamber volume) / Chamber Volume

cylinder volume = .7853982 x bore^2 x stroke.

chamber volume = thickness of head gasket + original combustion chamber volume


someone that knows their shit correct me if im wrong.
