Brian Crower Mitsubishi 4G63 EVO IV-VIII Camshafts - Stage 3+

The Brian Crower Stage 3+ camshafts for the 2003-2005 Mitsubishi Lancer feature a 272-degree intake duration and 272-degree exhaust duration, with 11.0mm of lift on both the intake and exhaust sides. These specifications are chosen to significantly increase airflow into and out of the engine, making them a popular choice for modified 4G63 engines looking for a substantial power increase, especially in the mid to upper RPM range. They are designed to work with the factory valvetrain, but upgrading to stiffer valve springs and titanium retainers is often recommended to handle the increased lift and RPM potential.

Crafted from high-grade billet steel, these camshafts are built for durability and consistent performance under demanding conditions. The Stage 3+ grind is a step up from milder performance cams, offering a noticeable bump in horsepower and torque, particularly when paired with other engine modifications like a larger turbocharger, upgraded intercooler, and a performance exhaust system. Installation involves replacing the stock camshafts, and while the factory valvetrain components can often be reused, ensuring proper timing and spring pressures is crucial for optimal results and engine longevity. This camshaft set is a solid option for enthusiasts aiming for a more aggressive power band and improved engine breathing.

Please note that these camshafts are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your mechanic or a performance tuning specialist to ensure these camshafts are the right fit for your specific build and intended use.
