I am sending my b20 block off to get sleeved soon, and I would like to know if anybody runs a 12.5:1 CR in their motors. If you do, what kind of upkeep/maintainence if required for this high of a CR? I already have a Hondata, so tuning is covered. What kind of power could I make out of this setup: sleeved b20, 12.5:1 CR, CTR cams, skunk2 valvetrain, eagle rods, light flywheel, 99 Si tranny, head that was port matched to the stock intake manifold and had the ridges before the valve seats removed and the entire thing mildly polished. Sorry for the long confusing sentence. Thanks!
