Actually...the b16b does share the same block height with the b18c5/1 motors. It is essentially a destroked jdm b18c R motor. The only thing it has in common with the b16a is the displacement and the higher revving capabilities. It also comes with a block girdle like the b18c motor, where the b16a does not.

Having said this, I would rather get a 1.8 :thumbup:
