![]() Akin to its predecessor, block keeps oil jets to cool forged aluminum pistons by Mahle. The motor is 220 millimeters high with a cylinder width of 96 millimeters. Its block keeps the partially closed deck, not a monoblock deck like 4G63. It’s a debut EVO motor featuring a die-cast aluminum cylinder block plus cast iron sleeves. 4B11T (Turbo) Engine Reviewīeing designed for Mitsubishi Lancer Evolution X, 4B11T is a 2.0L turbo version, applied as a substitute to 4G63T. ![]() The 4B11T is a high-performance engine with a long life expectancy however, it is naïve to expect it to be as reliable as its predecessor, the 4G63T. The non-turbo engine’s longevity is around 200,000 miles (320,000 km). As it features high efficiency, its lifespan is shorter than its non-turbo modification. The durability of 4B11T is almost similar to 4G63T. It is able to run for 200,000 miles (320,000 kilometers). It’s important to examine catalytic converter regularly as dirt from broken converter can get to cylinders and scratch them. Under pressure, they break into pieces, jolting within cylinders and destroying cylinders, valves, and spark plugs. Meanwhile, piston rings are weaknesses of turbo motors. Many motors, produced before 2009, have a stretched timing chain, leading to loud and unsteady functioning. Mitsubishi 4B11 Engine Problems And ReliabilityĤB11 works pretty loud, provoking much roar while warming up and becoming quieter when it’s warm. 2010 Mitsubishi ASX, Mitsubishi RVR (Canada).2009 Mitsubishi Outlander (Facelift Europe).Moreover, 4B12, a 2.4L modification, was created as an alternative to 4G64. Though these engines are a joint venture, they keep some specific details and can’t be used as substitutes for one another. The motor keeps an electronically operated multi-point fuel injection system along with fresh electronic ignition with iridium spark plugs and separate ignition coils for all cylinders for more eco-friendliness.ĤB11 pertains to Global Engine Alliance and is utilized for Chrysler, Mitsubishi, and Hyundai. Serving as a substitute for a timing belt, the timing chain controls both intake and exhaust camshafts, equipped with Mitsubishi Innovative Valve timing Electronic Control.Ī plastic cylinder head covering plus an intake manifold was utilized to decrease the motor’s weight. 16V aluminum cylinder head with a double overhead camshaft is located atop of cylinder block. ![]() Gaining an aluminum cylinder block with both bore and stroke of 86 millimeters, 4B11 is a steady and free-revving motor. As a result, 4B11 turns out to be an aluminum motor featuring modern electronics used in the latest 4G6 versions. Having naturally aspirated and turbocharged modifications, it was applied to Mitsubishi Lancer and EVO X cars. 4B11 is a 2.0L motor, released in 2007 as an alternative to the legendary 4G63 owing to stricter emission demands.
