A friend is going to rebuild his B16a when he gets it, but wants to know about the possible differences of the internals of the JDM vs. USDM B16's. Aside from pistons, and rods, what are the differences between the two?

Heads the same? Gaskets? Cranks? etc.

I searched H-T, and the Internet extensively, but couldn't come up with anything conclusive...which leads me to believe all the consumables are the same. Any help would be appreciated.

same, unless is the newer jdm b16's that have p30 pistons instead of pr3's.
Older b16's have less casting flaws also
