I measured my 1980 Euro S to static 9,3:1 compression (Porsche states 10:1 +0/-0,7). I think you can give that a moderate boost without getting into trouble

If the VIN begins WP0ZZZ92ZASxxxxxx then the car is an '80 MY which as Brutus mentioned above were made from August '79 and the car likely has the original engine.

'79 MY cars didn't have the new standardised VIN number that begins with "WP0ZZZ"; that was only introduced in '80 MY in Europe

'81 was first MY with 17 digit long VIN, '80 MY has its own 11 digit long number style. '79 first registration date can mean car is any one of these:

Code:
MY   Model     Market   Smallest VIN   Largest VIN   Qty  Total
---------------------------------------------------------------
78   928       ROW      9288100001        - 102646  2646
     928       USA+CAN  9288200001        - 201139  1139

80   928       ROW      92A08000011       - 101192  1182
     928       USA+CAN  92A08100011       - 101649  1639
     928 S     ROW      92A08200011       - 201466  1456   4277
As numbers say, ROW S model has different VIN sequence than same MY ROW 4.5L.

Ah my mistake - I just tracked back from KS (my car's 89) and figured AS would be the introduction of the 17 digit style.

MY engine came out of an 81 Euro S. Found it in San Antonio at a BMW parts recycler yard. AFAIK they were not available in the 79 models unless as previously stated, it was a really an 80 model retitled as a 79.
