GSC P-D Nissan VR38DETT S4 Camshafts 294/306 Billet (Use w/Methanol Fuel Only)

What you get in this package are a pair of GSC Power Division S4 camshafts, specifically designed for the Nissan VR38DETT engine. These are billet camshafts, meaning they are machined from a solid piece of steel for maximum strength and durability. The specs are 294 degrees of duration on the intake side and 306 degrees on the exhaust side, with a lift of .460" on both. It's important to note that these camshafts are intended for use exclusively with methanol fuel. This is a significant consideration for your build, as running them with gasoline will cause damage.

These S4 cams are a popular choice for VR38DETT builds aiming for serious power, especially when methanol is part of the fuel strategy. The increased duration and lift compared to stock allow the engine to breathe much more freely at higher RPMs, which is crucial for making big horsepower. Because they are billet, they can handle the increased stress and heat associated with high-performance applications. The 294/306 duration profile is designed to work well with other upgraded components in a performance engine, helping to optimize airflow and combustion efficiency. Remember that these are not CARB approved and cannot be shipped to California.

When installing these camshafts, you'll want to ensure your valvetrain is in good condition and capable of handling the increased lift and spring pressures. It's always a good idea to consult the manufacturer's installation instructions for specific details regarding setup and break-in procedures. Given their specialized nature and intended use with methanol, these camshafts are a serious upgrade for performance-oriented VR38DETT engines.
