The Mitsubishi 4B11T engine is the first engine for the Lancer Evolution to use a cast aluminum cylinder block rather than the cast iron block used in the previous 4G63T engine. Engine weight has been reduced by 12 kg compared to its predecessor, even with the addition of a timing chain instead of a belt.
Aluminum is also used for the timing chain housing and cylinder head cover. The 4B11T engine features an electronically controlled throttle, isometric short bore aluminum intake manifold, and a stainless steel outlet manifold located at the rear of the engine.
