!need a walk-thru on replacing stock pistons with high comp.!
i've got a 93 cx shell, with a ctr jdm swap-i threw a rod... didn't damage the block... but, that isn't the problem. i figured since i'll be in there, i might as well build it up a bit-and ordered the oem high-comp pistons, valves, and springs... problem is: i have no idea what i'm doing... lol
anyone willing to offer an in-depth walk-thru...? it would be much-appreciated... thanks
