About this engine family

The B-series are a family of inline four-cylinder DOHC automotive engines introduced by Honda in 1988. Sold concurrently with the D-series which were primarily SOHC engines designed for more economical applications, the B-series were a performance option featuring dual overhead cams along with the first application of Honda's VTEC system in certain models, high-pressure die cast aluminum block, cast-in quadruple-Siamese iron liners.
