The A20A3 was offered in the 1984-1987 Honda Prelude 2.0Si, the 19 Honda Accord SE-i, and the 1986-1989 Honda Accord LX-i. Again, there is no real difference between the A20A3 and the A20A4 besides the A20A4 having a slightly higher power output because of not having emissions components (hp and tq numbers for A20A3 only). They were run by Honda’s PGM-FI system on a partial OBD-0 computer. The A20A3 and A20A4 were the fuel injected versions of the A20A engines. They are the same engine, the only difference between them being that the A20A2 has no emissions components, so it has a slightly higher power output (hp and tq numbers for A20A1 only). It was available in the 1984-1987 Honda Preludes as well as the 1982-1989 Accord DX and LX. The A20A1 and A20A2 were the carbeurated versions of the A20A engines. They were found in both Accords and Preludes throughout the 1980s.

It was available in both carbeurated and PGM-FI versions. The A20A is probably the most plentiful of all the Honda A-series engines. Abroad, it was also available in the 1986-1989 Accords. The A18A engine was the 1.8 liter engine found in the 1982-1985 Honda Accords as well as the 1984-1987 Honda Prelude in the US. The A16A1 was a Carbureted 1.6 litre engine used in the 1982-1985 Honda Accords in North America and in some of the 1986-1989 Accords in the non-USDM market. This list includes most inline 4-cylinder engines only, starting in alphabetical order from A-series on. If you are unsure about which Honda engine powers your Civic you can look at this list for your year and model to see which engine you have.
