General
The 4G63T/C engine fitted in the Lancer Evolution VIII MR is basically the same as the 4G63T/C engine used in the Lancer
Evolution VIII.
The basic structure is the same in both the 6M/T (6speed) and 5M/T (5speed) versions, but the following improvements have
been made to the 6M/T version, in order to achieve higher performance.
• Adoption of 5ply cylinder head gasket
• Addition of Vshaped groove in piston , and modified shape in cooling channel
• Reduced oil consumption by increasing tension in piston rings and reducing endtoend gap
•Extra durability and reduced oil consumption by using new treatment on outer surface of oil ring side rail, and altering
thickness
•Lighter counterbalance shaft
• Increased output at high engine speeds by modifying intake cams
