The Honda A series inline-four-four-cylinder engine is used in 1980s Honda Accord and Prelude models. Introduced in 1982 with the second-generation Honda Prelude. Available in three displacement sizes: 1.6, 1.8 and 2.0 liters. It features cast iron block and aluminum SOHC head design with three valves per cylinder for a total of 12 valves. It was available in carbureted and fuel-injected configurations.
The Honda A-series engines succeeded the earlier EZ, ES, BS and ET engines in the Honda Accord and Prelude. There were several variations, ranging from the 1.6 liter A16A to the 2.0 liter A20A.
Beginning in the 1988 model year in the North American market, the A20A3 and A20A4 used a dual-stage runner intake manifold design, 4-2-1 exhaust manifold, and a more advanced electronic distributor. The Programmed fuel injection engines were equipped with partial OBD-0 engine computers.
The aftermarket has produced various parts for the Accord and Prelude A series engine. Most upgrades and modifications to the A-series engines are of the do-it-yourself variety, with one of the more popular being a turbo setup and OBD-1 conversion for more tuneability options.
The A16A1 was a carbureted 1.6 liter engine used in 1986-1989 Accords and Vigors outside the North American market. This engine was known as the EZ in 1984 and 1985, non-US Accords.
The A18A engine was the 1.8 liter engine found in 1982-1987 Honda Prelude and 1986-1988 Accord found in JDM models. Prelude A18A has twin side-draft CV carburetors (also named ET2 in some years) while the Accords came with single down-draught carburetor.

The A20A was available in both carbureted and fuel-injected versions. It has a SOHC 12-valve NON-CVCC cylinder head, with two intake valves and one exhaust valve per cylinder. They were found in both Accords and Preludes during the 1980s.
The A20A1 and A20A2 were the carbureted versions of the A20A engines. It was available in the 1986-1989 Accord DX and LX. 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.
