The production of the 4B11T was stopped in 2017 with the last Mitsubishi Lancer Evolution X. The exhaust manifold is made of stainless steel. The engine consumes a lot of fuel in this case, the engine got 540 cc/min fuel injectors. The 4B11T engine has a MHI TD05H-152G6-12T turbocharger with the max boost pressure of 1.54 bar (22 psi), air-to-air intercooler, aluminum intake manifold, and 60 mm throttle valve. The plastic cylinder head cover was replaced with aluminum one. But it gives to 4B11T a quicker response at lower and mid engine speeds. The third-gen 4G63 cylinder head had 20-percent better intake airflow over the 4B11 head due to smaller higher-velocity ports. The diameter of the intake valves is 35.0 mm the diameter of the exhaust valves is 29.0 mm the valve stem diameter of both valves is 5.5 mm. Like non-turbo 4B11, the 4B11T uses MIVEC continuous variable valve timing on both the intake and exhaust camshafts. The engine uses 16-valve (4 valves per cylinder) head with chain-driven camshafts. The bottom end features a four-bolt main cap and a two-piece oil pan design increases block rigidity. The connecting rod's length now is 143.75 mm.

Like the 4G63T, the block is equipped with oil jets for cooling forged aluminum pistons made by Mahle. The engine block height is a 220 mm the cylinder spacing is a 96 mm. The engine block has a semi-closed deck design (unlike the cast iron block with a solid-deck design of the 4G63). It is the first EVO engine with a die-cast aluminum cylinder block and cast iron liners/sleeves. The new 2.0-liter turbo engine replaced the 4G63T engine. The 4B11T was built specially for the Mitsubishi Lancer Evolution X. The new 2.4l engine replaced the 4G64 engine. Engineers also developed the 2.4-liter version based on the 4B11 and named it as 4B12. Despite the fact that this is a joint project, their engines have some unique features and are not interchangeable. The 4B11 is a GEMA engine and it is shared between Chrysler, Hyundai (G4KD engine) and Mitsubishi. The engine still has an electronically controlled multi-point fuel injection system and new electronic ignition with iridium spark plugs and individual ignition coils to lower emissions. For weight reduction, the engine was equipped with plastic cylinder head cover and plastic intake manifold (non-turbo version). The Mitsubishi's MIVEC system (Mitsubishi Innovative Valve-timing Electronic Control) is applied to both the intake and exhaust camshafts. The engine now uses a timing chain to drive both camshafts instead of a timing belt. The new 16-valve DOHC aluminum cylinder head is placed on top of the cylinder block. That also gave the ability to eliminate the balance shafts. The engine is well balanced and has a free-revving character. The new engine block has 'square' dimensions - bore and stroke are measured the same 86 mm. The Mitsubishi 4B11 engine has an aluminum cylinder block.
