"120Y" is simply the marketing name for a B210 or B310 with A12 engine. This name "120Y" was only used in some countries (markets). In other markets the same car was called "Sunny". The same car with A14 was called Sunny, 140Y or B-210. With A15 was called Sunny, 210, or 150Y. It depends on where it was sold. Newer FWD Sunnys also sported 130Y for E13 engine, etc.
