The 4B11T is the first engine in the Lancer Evolution series that uses a die-cast aluminum cylinder block versus the cast-iron block used in the previous turbocharged 4G63 engine that powered all previous models. The engine weight has been reduced by 26 lbs compared to the 4G63, even with the addition of a timing chain instead of a belt and MIVEC continuous variable valve timing on both the intake and exhaust camshafts (the 4G63 had MIVEC valve timing & lift switching type on the intake only). A revised turbocharger offers up to 20-percent quicker response at lower engine speeds compared to previous 4G63. The 4B11T offers a broader torque curve, producing more torque than the 4G63 at all engine speeds, helped by the engines square bore and stroke design (both measure 86.0 mm). Redline starts at 7,000 rpm, with a fuel cutout at 7,600 rpm to protect the engine. A semi-closed deck structure, an integrated ladder frame and four-bolt main bearing caps contribute to engine strength and durability. Unlike the 4G63, the 4B11T does not use a balancer shaft. Aluminium is used for the timing chain case and cylinder head cover. The engine features an electronically controlled throttle, an isometric short port aluminum intake manifold and the stainless steel exhaust manifold is positioned at the rear of the engine. The use of a direct-acting valvetrain (buckets) eliminates the need of the roller rocker arm configuration previously used in the 4G63 and its valve stem seals are integrated with the spring seats.

Note: Plug and play application. Short duration for nice street manners, slight lope at idle. Excellent all purpose spec. OEM spring OK.
