Honda B Engine

Honda B Engine

The Honda B-series are inline-4 DOHC automotive engines. 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 150 hp (112 kW) and 200 hp (149 kW), with some models capable of a redline over 8,500 rpm.

Allthough 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.

The Honda B-series was replaced by the K-series in Civic and Integra applications.
