Weird engine question

[Halo]

What differentiates one B16xx engine from another? To be more specific, what differentiates a B16B engine from a B16A2. Is it the combination of all the different components, or is it even more significant than that (ie. the engine block itself or whatever it's called).
A glance at the B-series engine article on Wikipedia gives me some idea as to the answer (that being 'yes' to both of the above) but I thought I'd go for a more knowledgeable answer.

Bonus points for links to relevant articles.

[Halo]

Three of those threads I had already read. I managed to somehow completely miss the one that answered my question. I'm an idiot.

Thanks!

I would just say that what B16A and B16B share in common is the fact that they have the same crank, and both being Dohc Vtec! The rest are for discussion! Every component contributes to the others so, everything is important even the fact that B16B has higher deck height
Bonus points?? I thought it was bonus($$$)

not exactly, that is somewhat of a misconception.

while the stroke of the b16a and b16b crank is the same, the cranks are NOT the same.

-the b16b crank uses the GSR/ITR main bearing size while the b16a uses the b16a bearing size (smaller bearing)
-the b16b crank is fully balanced
-the b16b crank is heavier, yes the b16B crank is heavier.
-the b16b crank will NOT fit in a b16a block and a b16b crank will NOT fit in a b16a block.

I meant they have the same displacement! My mistake!

-the b16b crank is heavier, yes the b16B crank is heavier.
-the b16b crank will NOT fit in a b16a block and a b16b crank will NOT fit in a b16a block.

Why are you repeating your phrases?? We got it ok?!?!

its just that most people are shocked to learn that the type R crank is heavier since the type R cars usually use lighter parts
