EVO X Components
Mitsubishi 4B11T Components
We've been busy engineering a complete range of motorsport grade components for the new Mitsubishi EVO X and the 4B11T engine. The all new engine features advanced architecture compared to the tried and trusted 4G63. It's all alloy construction utilizes a heavy duty main bearing girdle to promote block stiffness and a high flowing cylinder head with chain driven, twin MIVEC camshafts for a smooth flat power band. Relying on over 50 years of motorsport technology, we've developed some very exciting components that will allow you to achieve maximum reliable performance.
MX1 Camshafts - Available Now!
The 4B11T's performance is very impressive right out of the box, however there is always room for improvement. Older style camshaft designs used on the 4G63 are not ideal for the 4B11T and the new engine requires a different approach to camshaft profiles. The new Cosworth MX1 camshaft set will unleash additional performance and increase power across a large portion of the power curve. The Cosworth MX1 camshafts are ground from new blanks and have been engineered to be compatible with the original valve springs. Sold in matched pairs.

4B11T 2.2L Stroker Kit
Increased displacement means increased performance and the Cosworth 2.2L EVO X stroker kit is the perfect way to add power and torque to your EVO. Each kit includes select, matched motorsport grade components ensuring maximum reliable performance. Features billet steel, fully counter weighted crankshaft for smooth, high revving operation along with Cosworth forged steel connecting rods and forged pistons. The Cosworth 4B11T 2.2L stroker kit combines the perfect bore to stroke ratio, yielding potentially big gains in torque while still allowing the engine to rotate and produce power in the higher rpm range. Additionally, crankshafts, connecting rods and pistons are available separately.

4B11T Forged Pistons
With 50 years of world class engine design and manufacturing experience, Cosworth's intimate knowledge of the interaction between the piston and other engine components gives the us the distinct advantage in piston design resulting in the finest piston available. All Cosworth pistons are manufactured using the same methods as our Formula One pistons and include features such as anti-scuff skirt coating, ultra-strong pins, polished top and patented anti-detonation bands. Additionally, we have developed a completely new forging for the
4B11T to minimize weight and ensure the strongest possible piston
for maximum performance.
■ Skirt profi le & ovality technology - reduces engine noise, increases life & performance
■ F1 quality forgings - proprietary CosAl 010 for high stress applications
■ Oil and combustion gas control features - reduced blow-by and oil consumption
■ Offset pin bores - for reduced engine noise
