I've got a del sol with a b16 in it and i'm going to start building the engine up to take more boost, But my question is if i have a jdm b16a sir2 do i buy headstuds,pistons,rods and etc. for the b16? or do i have to get special ones for the jdm b16? Sorry if its a common sense question i just want make sure before i buy expensive parts. Thanks!

 

the block and head are the same across al B16a's in all countrys
the main diffrence is in the cams and valves and valve springs
with a small compression diffrence as well
the only special B16 is the B16B

 

So every thing engine related i can order b16 parts?
