Would anyone happen to know what the breakpoint in VIN #s is for "early" 1974 versus "late" 1974 914s?

I have owned both 'early and late' '74 2.0Ls.
Do not know of a definitive list of changes, nor the VIN inflection point which seems to be a progressive set of dates depending on the change, not a single date. The factory parts manual may indicate changes to spcific parts associated with a VIN. Some differences: -silver center gauges changed to black center gauges -charcoal canister relocated from fuel tank to engine bay rear wall -carpeting changed from solid colors to 'salt and pepper' patterns -a brief period of a few weeks in Spring of 74 when grey headlight relay covers were installed -fuel expansion chamber and fuel tank cap changed from metal to plastic Interestingly, the Can Am cars produced in the Spring of 74 include a range of these changes. Thats all I can think of right now. |

Well, what started me wondering is that in the 914/4 Tech Notebook there are two vacuum hose diagrams applicable to the '74 2.0, attributed to Jeff Bowlsby. One is for "1973 thru early 1974" and the other is for "late 1974". Sounds like there isn't a VIN cutoff point, so I'll just compare both diagrams to what I've got and see which matches. It's probably the late 1974 diagram since I have the black center gauges and charcoal canister in the engine compartment.

It's probably the late 1974 diagram since I have the black center gauges and charcoal canister in the engine compartment. I think that the only difference in terms of hoses is that the earlier 74s have the charcoal canister up front, like the 70-73 cars do, while the later 74s have it in the engine bay like the 75+ cars do. My 10/73 build 2.0 has the front-mounted canister. My old 1.8, which I think was also built around 10/73 according to the door jamb tag, had the canister in the engine bay. --DD |
