Why J-Spec B16a Engine?

The B-series Honda DOHC engines are popular automotive engines from the modern series of Honda engines. They are good performers from the factory having models with around 126hp to around 200hp, with even some models having a redline over 8,900 rpm. They accept high performance modifications well without much risk to reliability. The engine has been made in 1.6, 1.7, 1.8, 2.0, and 2.1 liter variants, with and without VTEC (Variable valve Timing and lift Electronic Control ). Later models have some minor upgrades, for instance modifications to the intake valves and ports and piston tops.
