2.0-Liter Engines: Under the 2.0-liter engine size Mitsubishi Motors manufactured engines under the 4B1, 4G6/ 4D6 (Sirius), and 4G9 engine platforms. Both of these engine series produced inline 4-cylinder engines in the single overhead cam (SOHC) and dual overhead cam (DOHC) configurations.
4G94 - This 2.0 Mitsubishi engine in the 4G9 engine series came with a cast-iron block, aluminum single overhead cam (SOHC) 16-valve cylinder head, and even forged steel connecting rods making it a fairly sturdy engine from the factory. It came in two different versions; The first version had multi-point fuel injection and a compression ratio of 9.5:1 to reach a horsepower rating of 123 hp. The second version came with direct fuel injection and an 11.0:1 compression ratio that helped it produce 143 hp in its stock form. These engines were commonly found in the Mitsubishi Montero, Mitsubishi Lancer, and Mitsubishi Galant.
4G63 - Found in the 4G6 engine series also known as the 4D9 or Sirius engine platform, this 2.0-liter Mitsubishi motor came in naturally aspirated and turbocharged forms as well as single overhead cam (SOHC) and dual overhead cam (DOHC) variations. The turbocharged version of this engine was dubbed the 4G63T and was rated at 271hp in most applications whereas the naturally aspirated 4G63 was rated at around 138 hp. These 2.0-liter Mitsubishi engines were found used as a 1980-2003 Mitsubishi Galant engine, a 1992-2007 Mitsubishi Lancer Evolution engine, a 1992-2007 Mitsubishi Lancer engine, 1990-1999 Mitsubishi Eclipse engine, and a 1990-1998 Eagle Talon engine.
4B11 - This is an all-aluminum 2.0-liter inline 4-cylinder engine manufactured by Mitsubishi Motors that has a 16-valve dual overhead cam (DOHC) cylinder head and variable valve timing (VVT) on the intake side. This engine had a compression ratio of either 10.0:1 or 10.5:1 and produced anywhere between 148 and 156 horsepower. It was used in the 2007-2017 Mitsubishi Lancer, the 2012-2013 Mitsubishi Outlander, and the 2018- present Mitsubishi Eclipse Cross.
4B11T - This is the turbocharged version of the 2.0 Mitsubishi engine. Like its naturally aspirated counterpart, this engine also has a 16-valve dual overhead cam (DOHC) cylinder head and variable valve timing (VVT). This engine, however, has a lower compression ratio of 9.0:1 to handle the increased boost from the turbocharger. This engine was rated anywhere between 287 horsepower in the U.S. market and was used as a 2007-2016 Mitsubishi Lancer Evolution engine as well as a 2008-2015 Mitsubishi Lancer Ralliart engine.
