General
The 4G63-T/C engine fitted in the Lancer Evolution VIII MR is basically the same as the 4G63-T/C engine used in the Lancer
Evolution VIII.
The basic structure is the same in both the 6M/T (6-speed) and 5M/T (5-speed) versions, but the following improvements have
been made to the 6M/T version, in order to achieve higher performance.
• Adoption of 5-ply cylinder head gasket
• Addition of V-shaped groove in piston , and modified shape in cooling channel
• Reduced oil consumption by increasing tension in piston rings and reducing end-to-end 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

2. Pistons
• Addition of V-shaped groove.
A V-shaped groove has been formed in the second land, with a view to reducing oil consumption.
•Modification of cooling channel.
The shape of the cooling channel, which recycles the oil, has been modified in order to improve recycling efficiency.

3. Piston Rings (2nd)
To increase the tension in the piston rings, they have been changed
to ductile cast iron, from the standard cast iron used previously.
The end to end gap in the rings was also reduced.
These modifications are designed to reduce oil consumption.

Tension 10.5 N 7.0 N
End to end gap 0.30 – 0.45 mm 0.35 – 0.50 mm

4. Oil Rings
The outer circumference of the side rail has been treated with chrome nitride. The thickness of the side rail has also been
reduced from 1.7 mm to 1.63 mm, with a view to increasing durability and reducing oil consumption.
(Evolution VII MR) (Evolution VIII)

5. Counterbalance shaft
The shape of the shaft was changed in order to reduce weight.
