Bourne HPP K-Series VTEC Lock Pin Set

Bourne HPP K-Series VTEC Delete / Lock Pin Set

Streamline your valvetrain for pure competition use with this VTEC delete and lock pin set. Designed for dedicated race engines, these pins permanently engage the high-lift cam profile, eliminating the variable valve timing mechanism to ensure consistent, reliable power delivery under the most demanding conditions.

By replacing the standard VTEC slide pins with these precision components, you remove the reliance on oil pressure and electrical solenoids to actuate VTEC. This modification not only simplifies the engine management but also significantly reduces mass in the valvetrain, helping to maintain proper valve motion and reducing the risk of valve float at extreme RPMs.

Performance Pedigree

These pins are essential for high-stress racing applications where consistency is paramount. By locking the rocker arms, you eliminate the risk of wiring or solenoid failures causing the engine to drop out of VTEC during a run. Furthermore, blocking the VTEC oil channels increases available oil pressure to the engine’s bottom end and camshaft spray bars, providing superior lubrication to critical bearings during high-RPM use.

Installation Note: This is a race-only modification that permanently engages the high-lift cam lobe. It requires specific ECU tuning to operate correctly. We recommend professional installation to ensure proper fitment within the rocker assembly.

We also recommend removing the VTEC solenoid and utilising a block off plate which can be found here
