This is taken from wiki:

A few D-series variants are labelled "ZC" (usually JDM), but they are not truly a different series.

There are both SOHC and DOHC ZC engines.

The non-VTEC SOHC ZC is similar to the D15Z4 and D16A6 engine, but with more aggressive cam timing.

The VTEC SOHC ZC is identical to the D16Z6, and the DOHC ZC is similar to the D16A1, D16A3, D16A8, D16A9 and D16Z5 engines.

thanks... i knew the specs of the zc but wasnt sure of the specs of the b2..

 

Don't mention it I know the bore is the same but i don't know if the stroke being different will make a difference in the pistons being able to be swapped.

 

if nething i may have to notch the rods.. kinda the same way when u put ITR pistons in an LS block
