Simon's Porsche 911 SC Site which has a registry for 911 SCs maybe yours is there from the PO you dont state where you live. Your VIN which is incomplete wp0zzz91zcs10 makes it an 82SC for sure the Carrera badge is wrong. Carreras only from 74 - 75 2.7 motor , 76 - 77 3.0 motor and from 84 - 89 was the 3.2 motor everything in between 78 - 84 was a 3.0 SC motor. Find your engine number to be sure.
