"How Hard Is It To Maintain a Turbocharger on 2003 Mitsubishi Evolution"

Blue 2003 Mitsubishi Evolution

What needs to be done to maintain a stock turbocharger in a 2003 Mitsubishi Evolution?

Answer: Nothing. Just make sure you use FULL Synthetic oil ONLY. Conventional oil will turn into sludge in the extremely HOT turbo. And the sludge will collect everywhere and eventually kill the turbo or even the engine.
