1974 914 1.8, the mystery of the EC-A and EC-B Options

[wonkipop]

i'll be dropping the information we have gathered over Dec 2021 in with a set of posts.

the material was prompted by mr b ( @JeffBowlsby ) who observed that for the 74 MY there was an EC-A and an EC-B engine. mr b's thought was that the EC-A was a 49 states car and and EC-B was a californian car for emissions.

mr b's view was rational and reasoned. 73 EA engines are 49 states. 73 EB engines are california. 75 engines are documented in factory literature as EC-a (49 states) and EC-b (california). the logic should follow?

BUT

as per the mystery of the 914, the truth about 74 1.8s turns out stranger than fiction (or common sense?).

the material is not necessary to running a 1.8 or having fun with a 14. (IMG:style_emoticons/default/smile.gif)

its for historical purposes and as information to 74 1.8 owners to assist with restoration if they want it.

just been scratching through my files here a bit more.

and there is this.
there was some controversy about this car,
it was up for sale on BAT a few months back and had some dodgy stuff where the original chassis number in frunk on top of wheel arch had been covered with a chassis plate from another car as well as the windscreen vin having been tampered with.

general conclusion in the end was that the vin sticker and the chassis number engraved under the false plate as well as the real plate on the headlight bucket were in fact the real numbers.

had some photos of it on file - i relooked at them,
it has a plastic expansion tank.
VIN 4742918919
K # 2119545. = mon 20 may 1974.
narrows the gap to the change from metal tank to plastic tank to window of
mon 13 may to 20 may 1974. looking like its sometime in week 20 1974.





i've gone back over all the examples i had on file and checked through them, and that was all i had.
but the green car above is a 2.0L car and we have been concentrating on 1.8 cars.
so there might still be some 74 cars on BAT archive that are cars built between these dates. when i get time i might try and pick through BAT looking at 2 L cars and see if anything else is there. (IMG:style_emoticons/default/beerchug.gif)
