Check this site for reasonably priced new turbos.Imported of course,but they seem to be decent quality from what I have read,not personal experience.Might be a good option vs a worn out oil-coked up used unit. https://www.maxpeedingrods.com/category/turbocharger.html
Go read the comments, if they aren't mostly fake I'll eat the turbo.
Now copy the part number, go to Amazon and read the comments there.
