The cylinder head intake and exhaust ports and intake and exhaust manifolds are shape optimized for improved volumetric effectiveness. Mitsubishi lowered the friction on the engine by which includes elastic grinding from the valve stems, adopting a superior-effectiveness shroud Geared up plastic impeller within the water pump and working with 0W-20 small-viscosity oil. Mitsubishi elevated the combustion performance by optimizing the look from the cylinder head intake and exhaust ports, by incorporating the MIVEC technique on both of those intake and exhaust valves and by making use of injectors that provide an ultra micro droplet gas spray.

5k so travel in and drive out all however they don’t tune it that's exceptionally important! I'm sure one individual who has turboed their manual two.4l, and about if is interesting, it might not be really worth the future repairs!
Using a direct-acting valvetrain eliminates the need in the roller rocker arm configuration Formerly Employed in the 4G63. The 4B11T options constructed-up hollow camshafts and its valve stem seals are integrated Along with the spring seats. The inner parts with the 4B11T engine are reinforced to face up to superior amounts of boost.[ten]
