I know Matto1kute asked "is there a book/manual on how to rebuild garrett turbos?"
and the answer is I don't know, sorry.

But he did also ask...
can turbo's be rebuilt at home?

I started my post with 'I think' (in other words - in my opinion)
I also said that 'here is a list of things done to mine'... I didn't say that he couldn't do it.

however, I do agree that the reco price is pretty steep... maybe there's more to it? I don't know, I've never seen the process.
