My Evo 8's 16G Turbo Looked NASTY Inside | Here's How I Saved It (4G63)

Is your Evo 8's turbo crusty, rusty, or full of oil residue? In this episode, I dive deep into restoring my OEM Mitsubishi 16G6 turbocharger pulled from my Evo 8 with the 4G63 engine. From flushing out the nasty coolant galleys, degreasing the compressor housing, cleaning up rusty banjo bolts, and checking wastegate actuator preload, this video shows everything I did to bring this old-school turbo back to life.

Whether you're dealing with blow-by, corroded coolant lines, or broken exhaust bolts on your TD05H 16G turbo, this video covers how to clean, inspect, and refresh your setup before reinstalling it. Plus, I discuss options like Heli-Coil vs. Time-Sert for repairing damaged threads in the hot side of the turbo.
