Product Overview
Skunk2 Tuner Series Stage 2 Camshafts – Honda B-Series VTEC
Unlock more performance from your Honda B-Series VTEC engine with the Skunk2 Tuner Series Stage 2 Camshafts, part number 305-05-0145.
Developed for performance-oriented Honda B-Series VTEC applications, these Stage 2 camshafts are designed to optimise horsepower and torque on engines equipped with supporting performance modifications. The cam profile is suited to builds featuring improved intake and exhaust flow, increased compression and an upgraded valvetrain.
Skunk2 publishes a potential gain of 15–20 horsepower and 16–20 lb-ft of torque, with an operating range of approximately 1,500–9,000 rpm. Actual results will depend on engine specification, supporting modifications, ECU calibration, fuel, installation and tuning.
Why Upgrade to Skunk2 Stage 2 B-Series Camshafts?
The camshaft is one of the key components controlling airflow into and out of an engine. By changing valve duration and lift, a performance camshaft can alter the engine’s power characteristics and improve its ability to breathe at higher engine speeds.
The Skunk2 Stage 2 B-Series cams provide a more performance-focused profile for enthusiasts looking to extract additional power from a naturally aspirated Honda B-Series VTEC engine.
They are particularly suited to properly built performance engines where the intake, exhaust, compression ratio, valvetrain and engine management have been upgraded to work together.

Designed for Performance Engine Builds
Skunk2’s Tuner Series Stage 2 camshafts are intended to work with engines that have suitable supporting modifications. For maximum performance, the camshafts should be matched to the rest of the engine rather than installed as an isolated upgrade.
Supporting modifications can include:
- High-flow performance intake system

Skunk2 Tuner Series Camshaft Technology
Skunk2 develops its camshaft range using computer simulation, modelling and testing. The company’s camshaft range is designed around performance applications, with profiles developed to improve engine power across the intended operating range.
The Tuner Series sits within Skunk2’s performance camshaft range and offers a Stage 2 option for enthusiasts looking for a significant upgrade over standard camshafts without moving to the more aggressive profiles in Skunk2’s higher-performance ranges.
Installation & Tuning
Camshaft installation should be carried out by a qualified engine builder or experienced technician. Correct cam timing, valve clearance and valvetrain compatibility are essential.
After installation, the engine should be checked and appropriately calibrated. Professional ECU tuning is recommended to take advantage of the additional airflow and to ensure the engine operates correctly with the new camshaft profile.
Incorrect installation, unsuitable valve springs or incorrect cam timing can result in poor performance or engine damage.
