I have a 1975 914-4. I checked my engine code the other day and saw that it was AO23451. I tried searching the 914 technical database but it doesn't even list an "AO" code for an engine of any year. I figured maybe somebody put VW type IV engine in the car but thesamba.com does not list an "AO" code for any VW's either.
Does anybody know what the hell engine I have? I was told by a previous owner that the WAS a 2.0 liter car but now I'm not so sure. |

VO is euro 914 could be 1.7, 1.8 or 2.0
AN is the high CR 1.8 914 AN and AT are 1.8 411/412 engines. New replacement cases had no number so a PO or wrench could have put any old number on it. |

I checked my information and I do not show an AO. There was an AN case for 1.8. Bus shows a AW for 1.8. There was a VO case that was magnesium for Europe. Does it have 3 bolt intake or 4 bolt? 4 bolt would make it a bus.

I just went to the garage for another look and found an "F" in front of the "A". Oops! That makes it FA023451. I still do not see an "FA" engine code in the system. It looks like a factory stamping, and it is a 4-bolt intake. Anyone?

If Rich is right it's a 1.7 from a 914 or T4 (411/412)

It's gotta be "EA" and then a zero. 72-73 1.7 liter.

You guys are good. Yes, it turns out that its a "EA" case. But I have the rebuild sheet so I know it has 1.8 pistons/cylinders in it along with a vanagon hydraulic cam. It sure runs great and has enough power for me. Thanks for the replies.

So, the engine was originally a 1.7L from Feb 1972.
Most likely a 1.8L now if the piston are 1.8 size. A Vanagon cam would not be ideal for making power though. |

It's got good low end power but really falls flat on the top end. But, I don't miss adjusting valves every 3000 miles!
