The only mechanic you can trust with your Mitsubishi Engine is Yasir, he understands that engine and car inside out, as he only works on Mitsubishi's.
Most of our desi mechanics do not understand the torque specs, tooling of the engine bloc, and will use third class parts.
You can google Yasir lancer, and go to his exact location, he doesn't have a fancy workshop but I can tell you that he does understand Lancer's like none. Being the owner of lancer myself, I was shocked by how much he knew about the engine and it's tinniest details, another good workshop is MotorHub, they work on exotic cars mostly, especially evos. So they understand Mitsubishi's as well.
