Brian Crower Toyota 1FZFE Camshafts - Forced Induction Stage 4

If you're building a serious forced induction engine for your Toyota 1FZFE, you're probably looking to get the most out of your turbo or supercharger setup. That's where a camshaft like Brian Crower's Stage 4 comes into play. These aren't your everyday camshafts; they're designed to work with higher boost levels and modified cylinder heads to really let your engine breathe when it's under pressure.

Brian Crower is known for making well-built valvetrain components, and these camshafts are no exception. They feature a more aggressive profile than stock, with increased lift and duration. This means they hold the valves open longer and further, allowing more air and fuel into the cylinders and more exhaust out. This is crucial for making big power with forced induction, as it helps the engine utilize the extra air being pushed into it. The Stage 4 profile is specifically tuned for engines running significant boost, so you'll want to make sure your supporting modifications, like the cylinder head and tuning, are up to the task. They are made from solid steel billets and ground to precise specifications to ensure consistent performance and durability.

When installing these camshafts, remember that they are designed for a specific purpose and will require proper tuning to get the most out of them. You'll also want to ensure your valve springs and retainers are up to the task of handling the increased lift and potential for higher RPMs. Because these are performance camshafts for a specialized application, they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance.
