SS-CAM (STEP1)
HKS SS-Cam are designed to fit unmodified cylinder heads with stock valve springs to be a simple bolt on cam kit that can give added performance without changing any other parts or the valve timing.
By changing cams, cam duration and lift are altered making the ideal valve timing different. HKS SS-Cams have been tested on the engine bench to find the optimum valve timing and the knock pin has been relocated in a modified position to offer perfect valve timing, by simply replacing stock cams with no need for measurement or adjustment.
STEP2 / STEP3 (Pro)
STEP2
Offering more power over SS-Cams through increased lift. However, strengthened valve springs (RB26 also require Piston recess modification and Cam clearance on head) are required.
STEP3 (Pro)
Camshafts designed for further power and high rpm use over step 2. The following parts will be necessary for installation: (SR20) HKS Lash Killer Kit, Need to change the strengthened valve springs.
