These Honda D series inline-four cylinder engine is used in a variety of compact models, most commonly the Honda Civic, CRX, Logo and Stream. Engine displacement ranges between 1.2 and 1.7 liters. The D Series engine is a SOHC and might include VTEC variable valve timing. Power ranges from 62 hp (46 kW) in the Logo to 130 PS (96 kW) in the Civic Si. D-series production commenced 1984 and ended 2005. D-series engine technology culminated with production of the D15B 3-stage VTEC (D15Z7) which was available in markets outside of the United States. Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled.

The D14A3 and D14A4 engines are identical, the difference is only one small gasket under the throttle body in D14A3 which restricts the air intake of the engine, this happen in some European countries.

The D14A7 and D14A8 engines are identical, the difference is only one small gasket under the throttle body in D14A7 which restricts the air intake of the engine, this happen in some European countries.

They are also almost identical to the D14A3 and D14A4 engines. Differences are only in the compression ratio and some different mounted components.
