New to the forum here...looking for a nice well documented 78 (or 79) 930- which will be my first foray into the Porsche brand. I’ve looked at a number of them and they have all had a 150 mph speedo. One 78 I’ve looked at claims really low miles, however it has a 180 mph speedo in it- Not sure if this is a red flag that the original was swapped out and replaced by this one...
I cannot say for sure what the correct one should be for that turbo, however all VDO gauges are date stamped on the back. Comparing that date to the date on the VIN sticker will give you a good idea if it is original or not.
The speedos are known for frequently breaking and being replaced. Seen it mentioned a lot. Not sure which would be right for the cars you are looking at but a replaced speedo is definitely not uncommon.
150 MPH is the correct speedo for 78 930, the later 79's used a federally mandated 85 MPH version

Thanks...that's what I was thinking. I'll see if they have any service records which could provide some/any form of mileage documentation or proof of a speedo swap.
Are you sure about that? I researched it once, and I think the 85 mph units were only mandated starting in September 1979 until around March 1982.

mark,
You are correct the 79 930 had a longer than normal build year as model was to be discontinued after 79. The 85 MPH speedo's were used in approximately the last 400 cars
