HKS Step 1 256 Intake Cam w/11.5mm Lift for Nissan S14 S15 1993-02 SR20DET NVCS 22002-AN023
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 an added performance without changing any other parts of 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.
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 redesigns 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 with 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
|

 |
Feature
- "Ultimate easy installation camshaft" is the concept of the product that outperforms competitors' products.
Improved performance for the range of more than 5,500rpm enables a "wide power band" for sport driving. The enhanced performance continues up to the revolution limit. -
The new camshaft profile has 11.5mm lift that was for STEP2 camshaft although it still can be used with stock Valve Spring. (Limitation: Stock revolution limit)
For more than the stock revolution limit, reinforced Valve Spring is required. (Limitation: 8,000rpm)
Vehicle specification
S15: GT-RS turbine, Metal head gasket, Exhaust manifold, Extension, Intercooler (S-type).
* As the thickness of the Head gasket is 1.6mm, the intercept point (RPM that boost reaches to the set boost level.) is shifted to higher rpm. This data is just for performance comparison of camshafts.
