How can I tell what engine I have? Long block? 1.7? 1.8? 2.0? How can I tell that the engine came in a 914 and wasnt swapped from a Volkswagen? How do I know when it was made and if it matches the transmission/rest of the car? How can I tell if my car is matching numbers?

Might help. Good Luck!

Porsche did not record the transmission numbers. If you want to pay them a bunch of money ($400 think ) and you tell them the engine number you have they will confirm if it is the original engine.

Try this one. It has all the 914 engine codes

Way better than what I put up there. Good call!

How do I know if the engine was made for a 914 and wasn't swapped from a vw? Thanks for the replies

I'm not positive, but I believe if it has any of the engine number codes in that list, it was built for a 914 and all other codes were for VW applications. Hopefully somebody who knows for sure will chime in.

Also, if the code is NOT on that list I posted, it isn't a 914 engine. Bus engines have the dipstick in a different place. You can do a search to find out how to tell if the dipstick has been relocated on a bus case to use in a 914.
