【Camshaft】
The Pursuit of Maximum Camshaft Efficiency
The concept behind the HKS 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.
HKS requirements for
high performance cams.
To smoothly take in air and exhaust, i.e. to make the valve move both in and out with accuracy under any circumstance.
Absolute power at high RPM
Accelerator Response at low-mid RPM
Stable idle
Development possible because of true "In-house" production
When HKS refer to "in-house", it does not simply mean to produce everything with our own facilities. HKS does build from the ground up instead of looking for a guide from the vehicle manufacturers. The design, processing, test and production are all linked together with particular attention, therefore, the testing and redesignings are based on those results. The results of this R&D are then reflected on the final production of the items. All of this is necessary to provide the customer a product which they can be truly feel happy with and to maintain HKS' position as the pioneer in the tuning industry
From "Bolt-on" to Full Tune-up Specifications.
The Right Profile to Extract Maximum Performance from Engine
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 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.
【V Camshaft】
The camshaft that is compliable for stock consecutive variable valve timing system. It was VALCON plus V CAM KIT Pro, but now Camshaft is available without VALCON unit.
FEATURES
- We recommend to use the valve timing with VALCON II to produce the maximum power of the camshaft.
- By using the variable valve timing, it can be used from the boost-up to turbine change.
