Honda B engine
Former Japanese automobile engines

The Honda B-series engines, introduced in 1988, are a family of inline four-cylinder DOHC performance engines featuring Honda's pioneering VTEC system in some models. Produced alongside the more economical D-series, B-series engines range from 1.6L to 2.0L and produce between 126 hp and 190 hp, with some capable of a redline over 8500 RPM. Notable for high-pressure die cast aluminum blocks and cast-in iron liners, the series includes variants distinguished mainly by cylinder block deck height. The B20B should not be confused with the earlier B20A engine. Over time, the B-series was succeeded by the K-series in several Honda models like the Civic and Integra.

B16B (Type R)

  • Found in:
  • Displacement: 1.6 L; 97.3 cu in (1,595 cc)
  • Compression ratio: 10.8:1
  • Bore x stroke: 81 mm × 77.4 mm (3.19 in × 3.05 in)

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’78

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.
