Rebuilt my Audi RS2 Turbo & Cerakoted it. Should be similar for 930/951 applications
 

Hey guys, just dropped a video of my first turbo rebuild. This one was BRAND new, so I didn't really need to replace anything, it was more about coating the center and turbine housings w Cerakote to protect from future corrosion.

Some of my actions (no T handle) are hack, but.... I was being careful :P

Not a hard job. I think anybody could rebuild a turbo, really. Biggest thing would be getting the rotational assembly balanced, generally have to send that out if you think it might not be. I marked my shaft/nut/wheel so hopefully it stays together okay. It's been a year and a half and no issues!
