2.7 MFI 911/83 engine value?
 

Anyone have any idea what a complete running 911/83 2.7 MFI engine is worth?

What is the shape of this engine ???

Is it complete ???

What have been done on it ???

.......etc.............

The price depends of the engine shape.

Here , it would be 3500/4000 euros for a complete & operationnal one , non rejuvenated.

Completly rebuilded by a mecanic , we would be close from 7000 euros.

Are you saying you have one?

Yes, complete from a 74 euro carrera. Runs great, all original. Mfi pump rebuilt by Pacific FI. Minor oil leaks.

It would be better if you gave more info like miles on the engine, work done on top end or rebuild miles, your location............

I would be interested in your motor. I have a '74 Euro Carrera. PM me.

You are kidding right?
A 911/83 engine rebuilt by a mechanic for 7000 euro.
You'd have guys lined up for this at that price. :rolleyes:

I know guys want deals, but please...

hdp951s - You have a rare and expensive engine on your hands.

Running condition -- $14K

I think a lot depends on how quickly you want to sell this. The engine will have the most value to the owner of the original chassis, and if it is a 73 motor, as opposed to a 74, you may have hit the jackpot. $14k would bring a pretty quick sale either way.

I bought one some years ago mate.

Ohhhhhhhhhhhh , i should read with more attention............i saw "1983" , so i thought it was a SC engine ,


Sorry.

A real MFI costs more.

Thanks for all the feedback. Here's my dilemma:
I have a 1974 Euro Carrera, but it is far from original. It has 930 flares, roll cage, race seats and harnesses. Bare metal re-paint in the late 90's, it is in nice shape. It is used as an occasional weekend toy, and a few DE events. I do not have the desire (nor the funds) to return this to an original 74 Euro Carrera.
Documentation shows the engine was replaced in Germany, in 1979, with a correct 911/83 rebuilt by the factory. This is not the original engine, but it is a correct 911/83.
What to do now? Sell the engine to someone who needs it for an original restoration? Or sell the whole car? What would the car be worth if someone had to reverse all of the prvious work?

Thanks for all the advice!

Where are you located? I'm thinking you may maximize your return by selling the engine separately. You could then buy an upgraded engine like a 3.0, 3.2, or 3.6 and have cash in your pocket or sell the roller separately and have a lot of cash.

Sell the car intact, if you want to get the most money for it.

I’ll have to agree with Mark (Pelican mreid), sell the complete running engine to THE person who needs it to make his (or her) RS complete.
Even better if you can find the ‘numbers matching’ chassis (unlikely unless it was a trade-in).
Advertise it for sale worldwide.

While I’m not an expert on current prices, I’ll speculate a sale price might be double (or more) the above estimate of US$14K to the ‘right’ buyer.
Keep in mind that this ‘mystery’ engine recently sold for US$112K to the ‘right’ buyer – and a bargain for him.

Keep the engine running and document the functioning (cylinder leak & cranking compression tests, chassis dyno data, etc. An engine dyno data and service would be great.)
Have the running car/engine available for a Pre-Purchase Inspection (PPI).

Spend some time and document the provenance of the engine.
Start with a bill-of-sale, service invoice, etc. from Porsche.
Was the engine a ‘new spare part’ or was it Factory rebuilt from a trade-in?
Try and ‘best possible’ document everything since.

The modified ’74 Carrera RS chassis still has real value. [ERROR] see next two post.
Since the engine is not the ‘numbers matching’ original, there is little downside to selling the engine and chassis separately.
You can keep the RS chassis and play using almost any engine.
You can sell the RS with another engine (3.0SC for example) to someone who wants to play and slowly collect the pieces to restore it.
There are lots of possibilities, particularly with new low-to-mid 5-figures in your bank account from the 911/83 sale.

Now, the exception to all this (selling separately) is if there was some interesting story behind the car and the replacement engine.
Who owned the car?
Why was the engine replaced?
Find the details.

I hope this helps.

Best,
Grady

Grady,

It's not a '74 RS, but a '74 2.7 Carrera. Still valuable...

JR

Dumb ol’ me. The meds are affecting my cognitive ability. Or just damn old age. :(

Ok, ’74 2.7 Carrera VIN 9114600001 to 9114601036 for coupes and 9114610001 to 9114610433 for Targas.
These 911s came with the 911/83 (90x74.4=2687 cc), 210@6300 engine.
A relatively low-production (1026 coupes sold) street model and the homologation model (460) for the RS 3.0 and RSR (both also MFI) in 1974.

The 911/83 engine numbers are 6640001 to 6641456 for 1974 models and 6630001 to 6631551 for 1973 models.
The numbers on this 'replacement' engine may give a clue to its origin.

EDIT
Mark,
You said the body/chassis had been modified with big fenders, roll bar, etc.
Could this be an RSR or racing modified Carrera RS 3.0 put on the street with a street 2.7 911/83?
If so, this could be very valuable. What is the VIN? It should be 911460xxxx if original 2.7. It should be 9114609xxx if RS or RSR.
The RS 3.0 and RSR numbers were interspersed among the ‘9’ numbers.
Not all of these cars (RS & RSR) have been accounted for.
Just thinking.

Best,
Grady

The 930 flares were put on in the early 80's in Germany, i have those receipts. The bare metal re-spray and cage were done in the late 90's.
Chassis # 9114600475
Engine # 6641398

If the engine is original to your chassis, keep them together if you want to maximize/preserve value. The 74 Euro Carrera, with the MFI engine is still a pretty rare car, and with a 73 RS approaching $500k, your car will start to look like a very attractive alternative at less than half the price of a 73. Think about it this way: you can easily return the car to the original body configuration - all the parts are readily available - but there is only one original engine.

It is not...

JR

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. :cool:

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.

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

Sweet

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.

Carrera MFI 2.7: Mexico Blue Stunner


$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.

Johan

fryardds, what is the significance of the AT?

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