1.7L HP, Why are the specs differing ? Options

[DANNYMAC]

I see 1.7L spec's all over the place, several list 80HP but some say 69 saw one stating 86 what gives ? All say Top End is 110mph but I just had my 1.7L at 110 and had some pedal left ?

Dont quote me on this, but I believe the California spec 1973 1.7s were only 69hp. I had a CA delivery 73 1.7 and it was noticeably slower than any other 1.7 (and any other 914 period) that I have driven and I recall reading at one point there was a difference with California delivery cars for that.

I think some of the difference in specs out there may have to do with specific country and differences between model year as there were far more differences delivered than just the 3 motor sizes (1.7, 1.8 and 2.0)

In the US alone the 1.7 and 2.0 motors had changes to its ignition and injection pretty much every year as well as the exhaust change in 75 and the added emissions in California. the 1.8s had quite a few changes that would have affected power between 74 and 75 as well.

And then there are the ROW delivery cars that were different as well. So really at the least there should be different specs for:

69-72 1.7 (79HP)
73 1.7 (69HP in CA)
US 73-74 2.0 (95 HP)
US 75-76 2.0 (87 HP)
ROW 73-76 2.0 (99 HP)
US 74 1.8 (??? HP)
US 75 1.8 (75 HP)
ROW 1.8 (84 HP)

and there are probably more than that as well.

Given 50 years of articles that just copy specs from other various sources the specific probably got lost somewhere along the way.

As for your 1.7 having pedal left at 110... 1. Is it stock and 2. Is your speedo accurate?

You don't list a 1.7 non CA ?

Quite a few i didnt list im sure. 73 non California should have been the EA code engine which is the same as the 69-72, though TBH every 73 1.7 I have ever seen has had the California EB code motor, though that could just be a side effect of having lived 23 years in California and the fact that a majority of surviving cars come from there (and the majority of cars were also delivered there)

My point wasn't really to describe every possible engine though but more to point out the fact that if you see a single generalized spec listed somewhere as the power output for a 914 its overlooking the fact that multiple variants were available even for a single displacement. Also that was 50 years ago, very few of these cars motors have been completely untouched in that time.

If you want to know what your car is putting out power wise, throw it on a dyno.

I guess I have an unusual situation, is one of the reasons I am asking. I have a 1973 1.7L 19688 original miles, sold first in Springfield Mass. Engine has never been touched, Basement stored until 2016 TRE in Van Nuys just replaced the original 1973 Clutch that was still with the car, verified "original"
