I'm currently running a stock JDM B16A3 long block and am starting a rebuild. I have B16A head with an ITR valve train and CTR camshafts. Since I'm going to have it apart, I was considering going ahead and swapping the P30(JDM B16A) pistons with the PCT(JDM B16B)ones. I also plan on using an OEM three layer head gasket. On Zealautowerks.com this would give me a 11.91 compression ratio. From what I understand, this should be pretty a straight forward swap. I haven't done this before & want to know if this will work, or if there is anything I am overlooking or need to change or do to make this a successful build. Your help is greatly appreciated!!!
