I am knew to 993's so forgive my ignorance. Was wondering if the VIN is on the engine somewhere on a 993 or is there a way to tell if the original engine has been swapped with another 993 engine.

Thank you!

The VIN is not on the engine. There is an engine serial number stamped on the engine case (right side, just under the fan housing). If you have Porsche pull the VIN details, they can confirm the serial number on the engine when built. The format is ##X-#####, example: 64W-01234. The last 5 are what is unique to your build and Porsche can provide you the details. 64W is unique to US/Canadian 1998 cars (such as mine).

About as best as you can do without going through this is confirming that the motor matches your specific year, market and trans type (manual vs auto) but of course you wouldn't know if it was swapped with a motor from the same year. Under the hood (frunk) there is a sticker that has an "engine code" section (not the same as "engine serial number"). So it will have your engine model and the first three letters/numbers that identify the year/market. Example: M6423-64W. So that means I have an M64/23 motor which is for a 1998 US/CAN car. (64W)

From there, I can look at my stamped engine case serial number and see that 64W-01234 falls in the range of 00000-20000 which is for all '98 US/CAN cars with manual trans. Automatics would have serial ranges of 50000-60000. Non-US/CAN cars (RoW - rest of world) would be 63W in 1998 instead of 64W.


Here's a link to all the 993 engine serial number ranges...
