Honda B engine: Information from Answers.com

The B-series Honda Outline (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).
