Description
Brian Crower Honda/Acura B18A/B Stage 2 Camshafts – Forced Induction Spec
Engineered specifically for forced induction non-VTEC B-series engines, the Brian Crower BC0021 Stage 2 Camshaft set delivers optimized cylinder pressure and airflow efficiency under turbo boost.
Overview & Performance Benefits
Purpose-built for turbocharged and supercharged Honda B18A, B18B, and B20B engines, the Brian Crower BC0021 Stage 2 camshaft profile features a short-duration design combined with maximum valve lift (.470″ / 11.94mm). By reducing valve overlap, these camshafts prevent compressed intake air from spilling out through the exhaust port, maximizing dynamic cylinder pressure and dynamic airflow efficiency under boost.
Every Brian Crower profile is precision CNC ground on state-of-the-art machinery to sub-micron tolerances, ensuring repeatable, dyno-tested performance gains and rapid cylinder charging for high-horsepower street and motorsport builds.
