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

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.
