| 914 Guru      Group: Members Posts: 5,185 Joined: 6-May 20 From: north antarctica Member No.: 24,231 Region Association: NineFourteenerVille    | 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. |
