Porsche 911 (964) Engine Codes

Porsche 911 (964) Engine Codes

The engine number is located on the engine block, on the right side of the crankcase next to the fan housing. The engine code consists of 8 digits and is the same for all versions. Example:

  • 62K86401 is an M64/01 engine installed in a 1989 Carrera 4 (normally aspirated).

Deciphering Porsche 964 Engine Codes

Note: Digit 4 is exclusive to Tiptronic models. In model year 1991 this number became a 5. So from this model year onwards the M64/02 engine for the Tiptronic could be identified separately.
