Bourne HPP Performance Billet Camshafts Honda K20/K24 Race (High Lift, Super Finished)

Bourne HPP 32R Billet Camshafts (Super Finished)

The Ultimate Race Specification

When second best isn’t an option, the Bourne HPP 32R Billet Camshaft is the definitive choice. Engineered for extreme applications, this is an all-out race profile machined from high-grade billet steel.1 It is the exact specification used in our own Bourne HPP K22 Honda NSX, proving its dominance in the harshest competitive environments.

Engineered for Extreme Output

Designed for fully built engines, the 32R profile utilises aggressive lift and duration to unlock massive airflow at high RPM.

• Forced Induction: The structural integrity of billet steel makes this the ideal choice for high-boost setups, supporting up to 1,000 horsepower.

• Naturally Aspirated: Capable of pushing high-compression N/A builds to over 300bhp.

The Billet Advantage: Super Finished Technology

What sets this camshaft apart is the manufacturing process. Machined from a solid billet blank for maximum tensile strength, these cams undergo a specialised super-finishing process.

This treatment polishes the camshaft to a mirror-like quality, significantly minimising friction losses. The result is a valvetrain that runs cooler, freer, and with greater efficiency—essential for endurance racing and high-boost applications where every horsepower counts.

Installation & Requirements

The 32R is a non-standard race profile that fundamentally changes how your engine breathes.

• VTEC Delete Required: To support this aggressive profile, the VTEC system must be removed.

• Fixed Cam Gears: Installation requires fixed cam gears (sold separately).

• Valvetrain Upgrade: Uprated valve springs are essential.

• Tuning: A professional standalone ECU calibration is required.
