A20A3

A20A3 & A20A4 The A20A3 and A20A4 were the fuel injected versions of the A20A engines. They were run by Honda's PGM-FI system on a partial OBD-0 computer. 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). The A20A3 was offered in the 1984-1987 Honda Prelude 2.0Si, the 1985 and 1989 Honda Accord SE-i, and the 1986-1989 Honda Accord LX-i.
