Template:Short description Template:More citations needed Template:Infobox automobile engine 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 (available in some models), high-pressure die cast aluminum block, cast-in quadruple-Siamese iron liners.[1]

To identify a Honda B-series engine, the letter B is normally followed by two numbers to designate the displacement of the engine, another letter, and in US-spec engines, another number. The Japanese spec-engines are normally designated with a four character alphanumeric designation.[2] The B-series, the B20B variant in particular, is not to be confused with the earlier Honda B20A engine introduced in 1985 and primarily available in the Prelude and Accord-derived vehicles from 1985 to 1991. 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.[3]

They were made in Template:Convert, Template:Convert, Template:Convert, Template:Convert, and Template:Convert 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 Template:Convert and Template:Convert, with some models capable of a redline of 8400 RPM.[4]

Although it has 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 distinction between them was the cylinder block deck height. The one used for B16 and B17 engines (except for B16B) has a deck height of Template:Convert while the short block used for B16B, B18 and B20 engines has a deck height of Template:Convert.[5]

The Honda B16 has appeared in six different forms over the years. The Honda B-series was replaced by the K-series in Civic, Integra, Odyssey, and CR-V applications.

Note: This engine uses the same block as the Integra Type R, which is taller than the B16A block, but with a crank the same stroke as the B16A. It uses longer rods to accommodate for this, which is why the Rod/Stroke ratio is higher than a standard B16. It is basically a ‘Destroked B18C Type R engine’[7][8]

  • Some came with limited production head P8R which had 33mm intake valves (normally found on VTEC B-series) vs 31mm intake (non VTEC B series), and the head had an 84mm shrouding vs 81mm for all other B series heads. They also had a thinner head gasket which yielded a higher compression ratio vs the normal B20B of 9.2:1.

B20B JDM

B20A/B20B

The B20A3 and B20A5 are the predecessor to the B family. All B-series engines were based from the B20A, but most engine components are not compatible. For more information, refer to the F3-series Honda race car that used a B20A engine. Also see Honda B20A engine.
