Actually, same stroke: A12, A13, A12A have same the same crankshaft.

A12A has 75mm bore. A12 has 73mm bore. So the pistons are bigger.

A12S is not emission, but 'S' is the newer Nissan designation for Single carburetor engine.

See A12A Engine

All single carb a-series are "S" engines (Single carb).
