The B16A is JDM, both the first and second generation JDM B16A engines where stamped B16A. The USDM engines have an additional number, such as the B16A2 and B16A3.
I would take a B18B over a B16A any day of the week. VTEC isn't everything, torque is. I'd happily take the extra 239cc of the B18B over the B16A.
