Turbo question

Rob Hughes

This is my 6 yr old turbo from Volvo tamd22 after being cleaned. I have a loss of rpm only able to get 2200. Is this rust color normal? I'm wondering about all the pitting. I have a new turbo on order. Just want to see if I have another issue that needs addressing. And if anyone has pictures of their turbo after cleaning could you share that please.
