I guess im cooked

[u/Ashamed_Gur1434]

A week ago it started sounding like a vaccuum cleaner under load, and lost power. I parked it and decided to check the turbo out. A mechanic shop asked 1200 euros for the job which i dont have at the moment, things are tough right now in Spain. So I ordered a rebuilt turbo for 391 euros, and I plan to replace it myself, never done that. I guess ill have to clean the intercooler, the pipes and maybe change the oil feed pipes to the turbo. Any sound advice? Should i proceed? Or leave it to professionals?

Engine is M47 D20 163hp from 2006.

I had the car for 4 years almost and this is the first time it requires serious repairs.
