HKS Step 1 Intake Camshaft 256 for Nissan S13 equipped with the 2.0L SR20DET.

HKS high performance camshafts are CAD designed to optimize torque and horsepower over the widest possible power band. Each camshaft application is offered in multiple profiles, each with their own lift & duration characteristics to suit various levels of tuning. Lower profiles offer substantial gains in power and a broad useable power band with little compromise in drivability. Higher profiles offer greater increases in power, but are tailored for the higher RPM range and racing applications. HKS camshafts are not reground OEM units; they are machined from new billet cores which are constructed from a high nickel content iron alloy. By manufacturing all camshafts from billet cores, HKS is able to produce camshafts that equal or exceed the quality of the OEM units they are designed to replace. HKS camshafts are direct replacements and are designed to be compatible with the factory valve train components. However, due to the higher profile of HKS camshafts, HKS high performance valve springs are highly recommended, and required in certain applications.

Features:

• Based on the concept of "the strongest plug-in cam in history," we conducted thorough comparison tests with our conventional products as well as with competitors' products.
  As the graph shows, the results show that the engine has a "stretch" from 6,000 RPM onwards, making it possible to use a "wide power band" during actual sports driving. You can also experience the "stretch" that continues up to the rev limit when actually driving.
• By reviewing the profile, the 11.5mm lift previously used in STEP2 is now compatible with the stock valve springs. (Upper limit: stock rev limit)
• If you want to increase the revs beyond the factory rev limit, you can do so by replacing the valve springs with stronger ones. (Maximum: 8000 rpm)
• Considering that there is no NVCS, the valve timing is set to ensure sufficient torque and emphasize high RPM. You can also adjust the valve timing with the slide cam sprocket to prioritize torque according to your preference.
