Can anyone point me to verified 914 engine number ranges? I have information on an available EC motor, but the number does not fall into the ranges I found, so I am wondering if it is instead a VW type IV motor. Sorry if this has been asked before, but I could not find anything in my search.

A 914 4 cylinder is a VW type IV motor. EC is a 74/75 1.8 engine.

Thank you for the quick reply. Based on this thread (http://www.914world.com/bbs2/index.php?showtopic=91988), there was an EC specifically for VWs, so I was not sure if this was a different motor or the same motor with a different layout (dipstick location, etc.). Also, I was not sure if it was frowned upon to reference other 914 forums, but I found a table that had engine numbers not going nearly as high as the motor in question. I can post a link if it is okay.

There were 17,773 1.8L cars made, so the engine numbers should go at least that high, not accounting for any additional stock or factory replacements.

EC is a 914 engine,
Just like the type 1,2 and 3 engines, the type 4's are all the same engine just drilled different for what car it's going into. Many times you will find a type 4 914 engine swapped into a bus, a bus engine in a 914 or 411/412.

There are other differences in heads, piston tops, valve sizes, etc. but for the 914 1.8 there's just a small bump in CR.

Thank you both! The power plant is still TBD, but I hope to contribute to this forum in a few months with a build that is just getting underway.
