2.7 MFI 911/83 engine value?

[Porsche84]

Hey Grady

What year should engine 66502xx be in. My friend has a 74 Carerra and his number doesn't fall in the range you stated above.

US Carrera or European Carrera?

(No, it is not a Monty Python joke, it really matters)

1975

Actually, I believe it is a European Carrera his Vin is 91146007xx and the engine is 66502xx

Interesting dilemma. I am assuming the 911/83 engine is in the car now. Do you want to sell the car? Do you need the funds from the sale of the engine for something else? If you want to keep the car and enjoy driving it don't sell either. As you know the MFI 2.7L is a great engine.

You will likely never find the chassis this engine was delivered with originally. You can't do a backward Cert. of Authenticity unfortunately. So unless someone out there in cyberspace, who owns the original chassis, knows this is matching engine to his car, and is looking for it, they will never be matched up.

If you want to sell the car then keep the engine with it. You have documentation showing it has been with the car since the late 70's so at some point (and that maybe now) it will make sense for someone to restore this car even with a non-matching engine.

There is one possibility though, because of the '460' VIN, this car can be used for historic racing in Europe, I believe, so in that case it might make more sense to split them up to maximize the sale. This would have to researched further though.

This is a “number type matching” situation where the car has the correct type engine.
Note the early VIN; number 475 out of about 1026* delivered.
The engine is much later in the series: 1398th (1026 plus 423 Targas for a total number of engines = 1449).
You should carefully inspect the engine crankcase for more stamped numbers and any casting-date indication.
What are the ‘parting numbers’ in the top of the crankcase, behind the fan?

I guess it all comes down to what you want to do. You have lots of choices.

I would do your best ‘due diligence’ and research the provenance before making any irrevocable decision.
Do you have the invoice from when Porsche AG installed the engine? Date?
Get the CoA from Porsche AG. This should have the original engine number (somewhere around 6640475)
Can you track backward from the prior owner?
Please post images of the documentation you have; someone may spot a clue.

Thanks Grady,
I have the CoA, and I have the receipt from 1979 showing the engine replacement. It was an independent shop, and it is in German, best I can translate, they installed a factory rebuilt engine, but I have no docs from Porsche AG.
I would prefer to sell the whole car for someone to restore. I would hate to split it up, even though it is not a "numbers matching" car.
On the other hand, I'm not going to give it away, I would sell the engine before I took a lowball price on the car.
I may place it in the classifieds to see what kind of response I get.

[Grady Clay]

Post a scanned image of the 1979 invoice (and any other). We can translate it.

Perhaps some of our German Pelicans can see if the shop is still in business or its records available.
I suspect you may be able to get Porsche AG to help identify the replacement engine if it was a ‘Factory Rebuild’.
It would be very useful to have the Factory Rebuild invoice.

Post the original engine number from the CoA. Perhaps someone knows what happened to it.

Don’t offer the car/engine for sale yet.
If you offer it for sale and someone ‘snaps it up’, you probably left a lot of money on the table.
If you ‘over-price’ it, you will run away potential buyers, some to never return.
Search the web for comparable sales of both 911/83 engines and complete ’74 RoW Carrera coupes.
Search for the most complete provenance possible.
Through research is your friend (and $$,$$$ in your pocket).

Best,
Grady

Biggest mistake in over 2 dozen 911 & 930 cars I have owned was selling my Euro 2.7 Carrera this past spring. Had the bug for a track car so I foolishly sold it, I did sell it to a somewhat local guy so I have visitation rights. The 911/83 was mated to a special 915 transmission, if you reach up along the top/front of the trans you should feel a "bump" which is a top sprayer (oil feed). Don't let the tranny go thinking it is just another 915. I watched the Euro Carrera scene like a hawk during my ownership. A few years ago, I saw a "tired" 911/83 that was ugly & needed freshened and MFI pump rebuilt that sold for 20 grand. Did I mention I hate myself for selling mine??

Here is what that tranny spray pump looked like for the RS. Beside it are the pick up pipe and the spray tube

Thought I would add a couple of pics.

Sweet

[fryardds]

Can you also post up a photo of the engine serial number? I'm curious if it is stamped with the letters 'AT'.

An orange Carrera 2.7 coupe, even with a non-matching 911/83 engine, is a desirable 911.

This was used on the RS and RSR transmissions until mid March '73 (almost till the end of the second series production). After that it was only used on the RSR.

$170K ask, numbers don't match, this car sat in a museum for many years. I am pretty sure it sold within the past 2 years for <$100,000 though because it was originally listed with Edmund Harris and I called him several times about it.

Hi,

I wouldnt separate car and engine when you have that much records. You will hurt the complete car value way more than you will get for the engine. I would sell it complete and buy another car. Sorry it is not a $100k car as implied above, probably not even $50k since not original, but you will get a 3.2 carrera and a pile of cash to spend on it.

I recently sold my Carrera, number 444, in a condition very much like yours. I advertized all over Europe and Ebay, so I think it is safe to say I got the market value. Please PM for details.


Regards,

Johan

[hdp951s]

fryardds, what is the significance of the AT?

[jsoderbe]

AT usually is a short for german "Austauch", meaning "replacement".
