Step1 (SS-Cam) Base radius 32mm
The Pursuit of Maximum Camshaft Efficiency
The concept behind the camshafts was to produce something that the customers would be truly happy with. This sounds simple on the surface but this is something very challenging. When the development team looked carefully at the details, the ultimate conclusion they drew was to look at the core purpose of the cam itself (to smoothly allow air into and out of the combustion chamber) and a good cam would do this job for the maximum efficiency.
Variation line-up
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 is altered making the ideal valve timing different also. 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. - STEP2 / STEP3 (Pro)
Camshafts designed for further power and high rpm use over step 2. The following parts will be necessary for installation: (SR20) Lash Killer Kit, Need to change the strengthened Valve Springs.
Improved performance and reduced cost is the concept with the latest profile design. It outperforms the previous models at lower price. Feel the performance.
HKS
In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Goichi Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan. A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.
HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
