Yea you're probably talking about the H2B (H22 and B Series transmission = H2B, clever rite?) anyways all I can say is a H22 swap is a pain and I think mounting it too a B series tranny is more complicated but they do have its for this& yes it is faster than a K series as far as I have seen, but I wouldn't go around calling a "K killer" but It really isn't much faster...
