Where is the location of engine number in evo 2 engine?

The location of the engine number on a Mitsubishi Evo 2 engine (4G63) is on the block, near the transmission bellhousing. It's often a stamped number, and might be partially obscured by grime or other components. You'll likely need a flashlight and possibly some cleaning to see it clearly. Precise placement can vary slightly depending on specific manufacturing variations.
