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...

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...
