No.....let me illustrate my point more clearly.....notice the difference?

those intakes are 4.5L Euro intakes. you are comparing them to US version.

yes, he has a 4.5L CIS M28/10 Euro car, the same as mine (except mine is a 5-speed car).

the front fenders are US spec, as described above, and should not be on this car (probably wrecked).

the hole in the rear quarter was probably an added maker light (I've seen quite a few with BMW markers) for federalization.

hope you get it running to see where you're at on restoration prospects.....

(my guess it was parked due to a TB issue, but that's no big deal on this one...)


not bad for $700.

After removing the door panels, the original color was Brown "like shown in your pic," it might be that one

No Russ, that engine pic I posted is from a Euro car, it seems that his car has 1 mismatched intake runner, maybe from an S? I was waiting for Jim Bailey to chime in

HTML Code:
 I see you have a rear fog light.
You mean the square one under the P of Porsche?

I think that is standard on Euro's, certainly mine has one

I just took a closer look at that hole in the rear quarter panel and it looks like a shabby hole, so I am sure it's not stock to Porsche.

of course the whole in the rear quarter is not stock, they were cut for rear markers when the car was federalized

Borys - It appears that someone put a Euro S intake tube in place of the original (second one back from Drivers side front). Hmmmmm....

So how much more is a euro S 5 speed worth? Thats what I have and I really never even knew people saw them as better than a standard 928. I actually thought it may be worth less because every time I went to the dealer the parts guys would give me the short speech about how they could not guarantee the part they had would even work on the car and it was not recognized as a valid car or something.

Sorry, Borys----

you posted a US spec engine (the brown 928). Look at the WUR. Compare with MP's Euro 4.5L engine....see the difference in the WUR mounting angles? Besides, the tubes are too small for M28/11 or M28/12.

try again----

MP--

try to get the casting numbers off of the intake tubes. I can reference these for you as I have intakes from 4.5L Euro, 4.7L Euro, and 4.5L US spec.

Let me know-

I went back a took a closer look at my M28/11 intakes.

The one in question on MP's car is the tube from a M28/11-12.

The rest are probably 4.5L Euro spec.

Wonder how it got there.......

Borys--I did confirm that the pic you posted was a US spec engine, I'll post pics of a 4.5L Euro intake and a M28/11 intake if it helps.

How did you confirm that?? Because of the WUR mounting angles????

The engine picture I posted I know for a fact to be out of a EURO 928, non S.

The WUR's seem to be mounted at different angles becuase the pictures were taken from different angles. The WUR's on a 928 AFAIK were only mounted in two ways..... sideways and top/bottom. All us spec CIS engines ended in 79 and they had the sideways mounted WUR and they all had a different breather system which vented the crankcase back to the airbox instead of back into the intake like the EURO cars starting in 80 did (see below)

http://928registry.org/Eurocars-1982-928-0240.htm

here is a US-spec CIS engine from a 79

Borys-

I mis-spoke... I should have said the aux air valve.

if the picture you posted was a Euro, and I now see that it came from a Euro on Chuck's registry, please explain why the aux air valve is at the same angle as a US spec engine....? May be it's just the camera angle, but it does not look at the same mounting angle as my Euro. This is why I made the statement about it being a US spec engine. A 4.5L Euro looks just like a US spec except for the aux air valve mounting angle, breather hose not withstanding. Sometimes it helps if you reference these in more detail.

I took your picture to be a Euro "S", which it is not (you later stated non "S").

As with other 928s on Chuck's registry, this one isn't correct either. It's not a Euro "S"........

Besides, who knows if any of these were original from the factory, and who knows what the stupid Germans did when they built them.....?

Maybe the intake tube on MP's car has been there from the beginning?????

To say that "it" is so may be correct for the majority of production, but there may be "mistakes' in that production as well?
