I have recently found a KKK turbo at a local pawn shop and want to know if I can use it on any of my cars. (350 chevy,472 Cadillac, and a Mitsubishi)

The ID plate has these numbers


Kund.NR D

Grosse K27-30646 11.90

atl-nr 85647-0243

UISF.NR 5327-980-6484

Thanks

The code says it's a K27, that's a good start.
Try to find out what it's off.
