HKS Camshaft 264 IN SR20DET Step2 S14/S15 NVCS

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.

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. 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.

STEP2 / 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.

In addition to the ""Ultimate easy installation camshaft"" STEP1, ""For higher rpm & Higher horsepower"", STEP2/3 are re-launched.
With the latest profile design, it outperforms competitors' products.
Feel the performance.

*Difference of STEP3 is valve timing only.

Feature

Target engine for both STEP2/STEP3 is more than 450ps and revolution limiter is at 8000rpm/9000rpm.

Test result shows it outperforms competitors products.

As shown on the left, the performance is improved from STEP 1 at more than 6,000 - 6,500rpm that is effective for large turbines.

* If turbine size is smaller than GT3037S, STEP1 camshaft is better for all rpm range.

Remarks

STEP2
Required parts: Valve Spring Upgrade or Head System STEP2. (Maximum rpm : 8000rpm)

STEP3
Required parts: Valve Spring Upgrade, Lash Killer Kit or Head System STEP3 (Maximum rpm : 9000rpm)

The designed valve timings are targeting best balance of horsepower and torque. Valve timing can be adjusted with Slide Cam Sprocket.
