Cosworth Billet Steel Crankshaft for the 2001-2007 Mitsubishi Lancer Evolution VII-IX 4G63BT / 4G63BT MIVEC (2.0L)

---

Cosworth Billet Steel Crankshaft for the 2001-2007 Mitsubishi Lancer Evolution VII-IX 4G63BT / 4G63BT MIVEC (2.0L) are designed for high performance and maximum horsepower and torque. This 94mm crankshaft is machined from heat treated EN40B steel and features an Isotropic Superfinish for superior friction reduction and lubrication properties. This revised crank is significantly lighter than previous versions and is available separately or in our 2.2L stroker kit and assembled high performance 2.2L 4G63 short block. Lighter rotating components help increase engine response and reduce the stress on other rotating components. This crankshaft is manufactured at Cosworth's world class facility in Northampton England. Unlike many respected companies now offering engine components that are allegedly manufactured at their facilities in Japan but actually made off shore, they control every aspect of design and manufacturing. And with over 50 years of engine design and manufacturing, Cosworth has the intimate knowledge of the interaction between engine components making their matched parts the perfect combination for maximum reliable performance. Upgrade your 2001-2007 Mitsubishi Lancer Evolution VII-IX with a Cosworth Billet Steel Crankshaft and experience the performance and reliability that has made Cosworth renowned in the performance aftermarket as well as racing circuits all over the world.

Isotropic Superfinish: The ISF Process is a chemically accelerated vibratory mass finishing process Any time two metal parts come into contact with each other, the resulting friction causes heat build up. These high temperatures cause wear and over time reduce efficiency and eventually create the need for replacement. By creating a smooth and shiny finish, the ISF Process improves the life and efficiency of moving metal parts. Increased life translates into lower operating costs as well as better performance. In extreme environments, such as automobile or motorcycle racing, every component must work in harmony at 100% capacity. Races are won and lost by fractions of a second, so it all comes down to getting the most power output possible. With the ISF Process, the energy normally lost to friction is now available in the form of increased power output. Once friction is reduced, the engine will run cooler allowing for longer durability of parts and fewer failures.

• Allows a freer movement of parts with less surface resistance
• Extends life of parts and reduces risk of part failure during operation
• Reduces maintenance expenses and fuel costs
• Improves oil shedding
• Increases power output resulting in increased speed
