What I mean is that it's the head that makes it high compression, not the pistons.
All 3s-gte are 1998cc (499.5cc per cylender) 499.5cc / 8.5 = 58.76cc (per head chamber) 499.5cc / 9.0 = 55.5cc (per head chamber) You see? Since the bore and stroke are always the same (86mm x 86mm), if the compression was raised using taller pistons it would take a different bore and stroke to achieve 1998cc This is just to give you an idea, Pi * R2 * H obviously doesnt factor in piston crown and head shape, and piston ring recess, but you get the gist of it. -------------------- Mike W
