I STFA and found 1 thread with no replies... Turbo part#? 53241015084. Is this the OEM turbo?

Maybe I am looking at the wrong number. This is printed on the housing. Shouldnt there be a tag
 

or something on there that has a number with letters on it? I did not see any type of tags on the turbo. Could it be under the intake hose?

That's the KKK P/N. Audi PN is 034 145 702. The RS2 turbo P/N is...
 

034 145 702B. And from the S-cars.org archives (linked in our FAQ) we get this:

RS2 Turbo FAQ

Part Numbers

RS2 turbo (Audi p/n)

034 135 703 D (old number)
034 145 702 B (new number)

RS2 turbo (KKK p/n)
53249707200 (7200 designates RS2)

research is telling me that is the number for a k24, cold side at least. Cant find anything else.
