PRP Street Series Cam Ignition Timing Kit - Nissan CA18

The PRP Nissan CA18 Street Ignition Timing Kit is a modern, simplified replacement for the factory cam angle sensor (CAS) found on single cam Nissan CA18 engines. Designed as an entry-level upgrade, this kit replaces the ageing OEM CAS with a reliable Hall Effect sensor setup, delivering a clean and consistent signal for your ECU—without the complexity of a full crank trigger system. Built for straightforward installation, the Street kit mounts directly to the camshaft and requires no modification to the harmonic balancer, making it an ideal solution for street-driven vehicles or anyone looking to upgrade from a failing factory unit. This is a cam-based ignition timing solution only and it does not include a crank trigger sensor. The Street kit is designed for: Easy installation Reliable street use Budget-conscious builds If you are running higher horsepower or require maximum accuracy under extreme load, we recommend stepping up to a system that includes crankshaft sensing. Key Features Direct replacement for OEM CA18 CAS Single Hall Effect sensor design for simplified setup Single or Twin Sensor 24-1 tooth trigger pattern on the camshaft Clean, stable signal for improved ignition accuracy No need to remove harmonic balancer Entry-level upgrade with PRP billet styling Power Recommendation Suitable for street and performance applications up to approximately 500–600whp. For higher horsepower builds, or engines seeing extreme RPM and load, consider upgrading to: PRP Race Series Kits These systems include both crank and cam sensors to eliminate timing inaccuracies caused by belt stretch. ECU Setup Notes Trigger pattern: 24-1 (camshaft speed) As this kit runs off the camshaft, it operates at half engine speed ECU configuration will need to reflect a cam-based trigger input This kit using a Single Sensor will NOT WORK with a Haltech Platinum Pro or any other older model ECU that does not support a 24-1 cam trigger If you are using a Haltech Platinum Pro or older ECU models, please select the Twin Sensor version - If you need clarification on which kit you need, please reach out prior to purchase Why Upgrade from OEM CAS? Factory CA18 cam angle sensors are now decades old and prone to failure, signal inconsistency, and timing drift. The PRP Street kit provides a modern, reliable alternative with improved signal quality and long-term durability.
