Nissan/Infiniti Cam Kit (PR)

The Nissan/Infiniti Cam Kit (PR) from SPC PERFORMANCE is an essential valve train upgrade designed for enthusiasts and mechanics seeking precise engine tuning and performance optimization. This kit is engineered for owners who demand tighter valve timing control, improved throttle response, and the ability to fine-tune their engine's breathing characteristics. Whether you're building a high-revving drift car, optimizing a street performance engine, or dialing in a track-focused setup, this cam kit provides the adjustability required for serious engine builders and tuners.

SPC PERFORMANCE's cam adjustment solution uses precision-engineered components that allow you to rotate the camshaft relative to the crankshaft, effectively altering valve overlap, intake, and exhaust event timing. This cam kit works by adjusting cam phase—the relationship between cam position and crank position—which directly influences cylinder scavenging, fuel atomization, and volumetric efficiency. The compact 2.5 x 5.5 x 5.75-inch design (1.44 lbs) integrates cleanly into tight engine bay configurations while maintaining durability under sustained high-RPM operation. Precision tolerances ensure repeatable adjustments, making this kit ideal for dyno tuning sessions where 1–2 degree increments can unlock measurable power gains.

This Nissan/Infiniti Cam Kit (PR) is best suited for owners of VQ-series engines—including applications in 350Z, G35, Altima SE-R, and Maxima models—who are pursuing mid-range torque increases or peak RPM optimization. Installation requires basic engine bay familiarity and proper timing mark alignment; it pairs seamlessly with bolt-on modifications like cold air intakes and cat-back exhausts, or integrates into comprehensive turbo and supercharger packages. Tuners and engine builders will appreciate the incremental tuning capability this kit provides, particularly when combined with piggyback ECU tuning or aftermarket standalone engine management systems for maximum synchronized results.
