Revision as of 15:32, 10 April 2009

The B-series Honda inline (I4) DOHC(Dual Overhead Cam) engines are popular automotive engines from the modern series of Honda engines. From the factory they produce between 126 horsepower (94 kW) to around 200 horsepower (150 kW), with even some models having a redline over 8,900 rpm. The engine has been made in 1.6, 1.7, 1.8, and 2.0 liter variants, with and without VTEC (Variable valve Timing and Electronic lift Control). Later models have some minor upgrades, for instance modifications to the intake valves and ports and piston tops, along with individual cylinder oil injectors (b18c_ models).

B16B (Type R)

VTEC
Found in:
- 1997-2000 JDM Civic Type R[EK9]
  - Displacement: 1,595 cc (97.3 cu in)
  - Compression: 11.0:1
  - Bore: 81 mm (3.2 in)
  - Stroke: 77.4 mm
  - Rod/Stroke ratio: 1.84:1
  - Rod Length: 142.42 mm (5.607 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'
