SKUNK2 Camshafts B16A B18C Integra GSR / Civic Si VTEC CAMS PRO 3 + 305-05-5150
Gain an extra 25+ hp with Skunk2’s Pro 3+ Camshafts, our professional line of high-lift, racing camshafts for Honda’s B-series VTEC engines. Pro 3+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, raising peak power 700 rpm higher than what Pro 2+ Camshafts allow for. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2’s Pro Series.
Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of newly revised chill-cast, billet camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.
Skunk2’s Pro Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response from idle to redline. AMAX technology simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power. And thanks to Fast Ramp, the same technology used in Formula One racing, seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.

Please note: When using camshafts with greater than 12.6mm of lift, the following components must be used due to the stock lost motion assembly’s limited ability for maximum camshaft lift. Failure to do say may result in potential engine damage:
• Skunk2 Pro Series Valve Springs (P/N 311-05-5350)
• OEM Honda lost motion assembly (Honda P/N 14820-PCB-003 or Honda P/N 14820-PCB-305) Important: must use shims with P/N 14820-PCB-003.
