Performance & Compatibility

Variable Valve Timing (VVT) is ideal for stock and mild-performance setups, but becomes restrictive in boosted configurations. The TSP 3-Bolt Turbo Camshaft eliminates the limitations and potential failures of factory VVT systems—providing superior performance, reliability, and tuning accuracy under boost. With no risk of sheared pins or misaligned phasers, the 3-bolt design dramatically reduces installation error and increases overall engine safety and performance.
