Ever wonder which engine you REALLY have in your Porsche? On the 924S/944/968 series cars you can find the engine designator stamped on the block.
MY 83-87 - The engine number is stamped into the left-hand rear crankcase section.
MY 88-95 - The engine number is stamped into the right-hand rear side of the engine, just below the #4 exhaust outlet.
Now, what are the different engines available? Look for the Tech-Session article regarding production information
