Product Description

The Skunk2 Pro Series Stage 2+ Camshaft Set (part 305-05-5145) is a performance-oriented upgrade designed for the Honda/Acura B-Series VTEC engines (1.6 L to 1.8 L) in the 1992-2001 Integra and 1994-2000 Civic / del Sol models. With its aggressive lift and duration (~12.65 mm intake / ~11.90 mm exhaust; ~260°/272° respectively), it yields solid mid-to-high rpm power gains while maintaining engine response and drivability in the right build.

Manufactured from precision CNC-ground, chill-cast camshaft blanks featuring Skunk2's Fast-Ramp & AMAX technologies, this cam set delivers a broader powerband and improved throttle response. It is ideal for naturally aspirated or lightly boosted B-Series VTEC builds with upgraded valvetrain components (valve springs, titanium retainers, lost motion assembly) and tuned engine management. Installation requires degreeing the cams, setting correct valve clearance, and ensuring proper supporting hardware.
