HKS RB26 Vcam System Step1 (wo/Valcon RB) 22007-AN020

RB26DETT engines in the R32, R33, and R34 Skyline GT-R gain significant performance improvements with variable valve timing that enhances power across the RPM range. The HKS RB26 Vcam System Step1 (without Valcon RB) (22007-AN020) is an affordable upgrade that modifies the intake cam side to allow variable valve timing. With a conservative 248° duration, this system unlocks additional power at both low and high RPM, providing stronger acceleration and a more responsive driving experience while reducing the need for frequent gear changes.

HKS has engineered this system to promote more complete combustion, resulting in improved fuel efficiency and cleaner emissions. It is designed to work seamlessly with stock pistons, making it a convenient upgrade for many builds. For optimal results, HKS recommends pairing it with specific exhaust cam profiles such as GT-SS 256° or GT2530 264°, ensuring compatibility with stock pistons. Note that thinner head gaskets or modified cylinder heads may require additional clearance checks to avoid valve-to-piston contact.

At Terra Firma Automotive, we supply this genuine HKS RB26 Vcam System Step1 as a premium valvetrain upgrade for RB26DETT owners seeking better low-to-mid range torque and overall engine response. It transforms your RB26 into a more versatile and powerful unit while maintaining reliability for street and track use. For enthusiasts serious about optimizing cam timing and unlocking additional performance, this HKS Vcam System is one of the most effective upgrades you can make to your Skyline.
