Chronology

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 2.0Si,1986-1989 Honda Vigor and Accord. 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.

They were made in 1.6-, 1.7-, 1.8-, and 2.0-liter variants, with and without VTEC (Variable Valve Timing and Lift Electronic Control). Later models have minor upgrades including modifications to the intake valves and ports and piston tops, along with individual cylinder oil injectors (B18C models). They produce between 130 hp (97 kW) and 200 hp (149 kW), with some models capable of a redline over 8,500 rpm.

Although it has so many variations, the basic design differs very little among the B-Series. There are actually two short blocks which are used for the entire series. The main difference between them was the deck height. The one used for B16 and B17 engines (except for B16B) has a deck height of 203.9mm while the short block used for B16B, B18 and B20 engines has a deck height of 212mm.[1]

The B - series engines have become the most coveted Honda engines due to their reliability and the ability to produce high horse-power relative to their displacement. The major benefit of the B-series engine is also the ability to be transplanted into various Honda chassis, such as the Honda Civic. Best of all, Honda and Acura dealerships nationwide still have huge support for the B-series and it's factory parts.

The Honda B16 has appeared in 6 different forms over the years. To identify any B-series engine, the letter B is normally followed by two numbers- which designates the displacement of the engine-another letter and in the case of US-spec engines, a final number. The Japanese spec-engines are normally designated with a four-digit alphanumerical designation.[2] The Honda B-series was replaced by the K-series in Civic, Integra, and CR-V applications.
