????Bottom end,,with what pistons?????
OK I have a b16a2 j-spec and I really don't know the piston size I have??? Oh and the bore of my cylinders???? Also what pistons could go in this bottom end. I know if I put ctr or itr pistons; in it would I need to bore the block out???? Any help would do....All I know is that I need something bigger than my stock pistons......

the size of your pistons is 81mm and if you want to go with ctr pistons you can get oversized ones that are 81.25mm
also there are alot of companys that make pistons for that engine in all sorts of sizes from 81mm to 86mm or something like that?

Correct. Also you if you have a JDM motor, you don't have a B16A2, you have a second generation B16A. It should be equipped with P30 pistons. I'd jump up to the .25 over CTR pistons, and later upgrade the cams. The stock bore on the B16 is 81 mm.
