initially i was just stating that taller pistons will affect the compression ratio w/o affecting the total volumetric displacement of the engine (1998cc) assuming both heads are the same. now that we know the rods and pistons are the same, then the difference is definitely in the head design. i believe Smaay's post about how head design having no effect on the CR is incorrect. by altering the head chamber, it will also alter the volume of the head chamber at TDC which also alters the CR. just to clarify, factors that affect the CR are the pistons, rods, crank (which alters the stroke), and even head gasket thickness. however, the total volumetric displacement of the engine (1998cc) remains unchanged as long as the bore and stroke remain unchanged.
delusionz, you're absolutely right in that you can have different cc's when using different generation heads. but just to be clear, the primer is referring to cc's as the volume in the head chamber, not the total volumetric displacement (1998 cc). -------------------- -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- |
