What cam belt?

I'm changing my head for a machined skimmed and all new gasket one I'm doing so while the block is split I though I might as well change my oil and water pumps too.
As I'm looking to go turbo on my B16 I'm going to put in B18 oil and water pumps. From what I remember the B18 pumps have more teeth on the drive gear am I right???
If so what cam belt should I use for the build???
