The B-series are a family of inline four-cylinder DOHC automotive engines introduced by Honda in 1989. Sold concurrently with the D-series which were primarily single-cam engines designed for more economical applications, the B-series were aimed more as a performance option, featuring dual-overhead cams along with the first application of Honda's VTEC system available in some models. The B-series, and the B20B variant is not to be confused with the earlier Honda B20A engine introduced in 1985 and primarily available in the Honda Prelude. While sharing some design elements and both being multivalve Honda four-cylinders, the B-series and B20A differ substantially in architecture, enough to be considered distinct engine families. We have repaired and re-built the B16 series engines for many clients. Call for an estimate today.
