What is the primary benefit of the 290/290 duration on these camshafts?

The 290-degree intake and exhaust duration means the valves stay open longer. This allows for increased airflow into and out of the engine cylinders, which is crucial for making more power, especially in high-RPM performance applications.

What does 'billet' construction mean for these camshafts?

Billet refers to the manufacturing process where the camshaft is machined from a solid block of steel. This results in a stronger, more durable component that is less likely to flex or wear under high stress compared to cast camshafts.

Are there any restrictions on shipping or installation for these camshafts?

Yes, these camshafts are not CARB approved and cannot be shipped to California. Professional installation and ECU tuning are also highly recommended to ensure proper function and maximize performance gains.

Product Details

These GSC Power Division S4 camshafts are specifically made for the Nissan VR38DETT engine found in the GT-R. If you're looking to significantly upgrade your engine's breathing capabilities for high-performance applications, these camshafts are a solid choice. They feature a 290-degree intake and 290-degree exhaust duration, which means they stay open for a longer period, allowing more air and fuel into the cylinders and more exhaust out. This is key for making more power, especially at higher RPMs.

Crafted from billet material, these camshafts are well-built and designed to handle the stresses of a performance engine. The billet construction offers a strong foundation that's less prone to flexing or wear compared to cast cams. The S4 profile is a popular choice for serious engine builds where maximum airflow and power output are the goals. Installing these will require a good understanding of engine timing and potentially other supporting modifications to get the most out of them, such as upgraded valve springs and ECU tuning.

It's important to note that these camshafts are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and timing procedures. For optimal performance and reliability, professional installation and tuning are highly recommended.
