The high-revving heart that defined Honda's performance era

In short: Introduced in 1988, the Honda B-series engine transformed the brand's reputation. By pairing dual overhead cams with the revolutionary VTEC system, these engines offered a level of high-RPM performance that challenged the boundaries of small-displacement motoring, paving the way for a new era of enthusiast driving.

The B-series family, launched in 1988, was designed as a high-performance alternative to the more economical, single overhead cam D-series. These engines featured a high-pressure die cast aluminum block with cast-in quadruple-Siamese iron liners. While the basic design remained remarkably consistent across the series, the family utilized two distinct short blocks differentiated by their cylinder block deck height: 203.9 mm for B16 and B17 models, and 212 mm for the B16B, B18, and B20 variants. To identify these engines, the letter B is typically followed by two digits denoting displacement, an additional letter, and sometimes a further number for US models. Japanese-specification units are generally identified by a four-character alphanumeric code.

A defining characteristic of the series was the application of Honda's VTEC technology, which stands for Variable Valve Timing and Lift Electronic Control. This system allowed certain models to achieve extraordinary performance metrics. Some variants were capable of reaching a redline of 8400 rpm, providing a visceral driving experience. The range of displacements was diverse, spanning from 1.6 L (1,595 cc) up to 2.0 L (1,973 cc). The B20B variant is notably distinct from the earlier B20A engine introduced in 1985. Although both are multivalve four-cylinder units, they belong to entirely different engine families due to substantial architectural differences.

The power output across the series was equally varied, ranging from 126 hp (94 kW) to 197 hp (147 kW). Later iterations saw technical refinements, such as the B18C models, which featured individual cylinder oil injectors and modifications to the piston tops, intake valves, and ports. Eventually, the B-series was succeeded by the K-series in various Honda applications, including the Civic and Integra. The B16A block is shorter than the one used for the Integra Type R. To compensate for this, the latter uses longer rods to maintain the same stroke.
