'74 911s Carrera w/ '73 RS engine

[Treeman]

I don't have the time, money or knowledge to restore it. The car is a 1974 911s Carrera, with a 1973 RS engine with 56k miles, motor is not locked up. Will need extensive work inside and outside.

What is a good price range to sell a 1973 rs engine and transmission? I don't want to get any less than it might be worth! Do I sell it on a forum or put it on ebay? Pix and numbers on request.

The engine is not running correct?

The value will be based on verification it is indeed an original '73 RS case and can be rebuilt if not running. Value will also be determined by the presence of the original MFI system. Can you give us the serial and type # of the transmission?

So based on the information it is really hard to give a good answer to your question about value.

Here is a link to to my original post on the Forum

74 or 73 / RS or Not

I had high hopes when I first got the car, now with two in college, it might need to go. I do not know where to locate the trans. #
If you can tell me I will post it Monday evening. Thanks

Do not know where to find trans #

[fryardds]

The serial and type number are stamped on the very bottom of the transmission, where the clutch cable passes through. Many times these number are hard to read because they have been ground off by sliding the transmission around when it is out of the car. This example has a serial # of 7720075, but the type # is gone.





The correct serial # for a '73 RS transmission is 783XXXX and the type # is 915/08.

Can you send me photos of the engine serial #? Thanks.

[Treeman]

Parents weekend at A&M, I will get under the car as soon as possible and get the number.

Offer and let market determine. I see values all over the place... I would auction.

Treeman ,

A few pointers. Theres is no such thing as a 1974 911S Carrera. It is one or the other : a 1974 911S or a 1974 Carrera . If a Carrera , it can be US or European Spec. (two completely differant animals) .

When you say a 1973 RS motor, do you mean a 1973 motor built to RS 2.7 specification ? Or a correct serial numbered 1973 RS 2.7 motor from a 1973 Carrera ? If the latter , you need to supply the serial number . And a good photo of the serial number stamping...IF you wish to be taken seriously.

An original serial numbered motor , has the most value to the car it came out of. To any other , substantially less. Also , if an original engine case (where the ID numbers are stamped) , value also depends if the auxilary components are original.

I crawled under the car, and it does not look the same as your picture? So where else would the trans# be?

Are you not more concerned about verifying the motor ? I guess this is going to be another chasing info. deal.... you get but don't give.

[Treeman]

fryardds here is my picture, no numbers?

This car/motor/trans has been around here before (previously stated to be owned by poster 'Arbola' ) . Some comments/info. previously provided by the forum.


Thread / 74 or 73 / RS or Not :


Fryardds / 03-24-2009, 10:10 AM :

"That RS engine was originally delivered in RS 9113600873 which was/is Grand Prix White w/ red graphics. Probably no longer around but you never know."

"I rebuilt this engine back in the early to mid 80's. I probably still have the build sheet on it somewhere. The car came to us along with two others out of Germany. I had a 73 RS myself, so we rebuilt this engine, which was in a flared 74 S chassis. I sold it to the gentleman that the new buyer purchased it from....many years ago. I'll try to dig up more info on this soon.

"Good thought The matching transmission # for the engine is 7830852 the type is 915/08 for the RS. On March 19th '73 the transmission cooler was no longer used on the RS transmission. The car this engine was in was built sometime in March '73 so it may or may not have the cooler on the trans."

From a quick look , the motor stamp seems qeniune to me.

Seems funny that the original car is not surviving, as it was here in the U.S. , apparently came in to the U.S. with the RS that Scott St. Peter restored and sold


Good luck

Oops, looks like I made a mistake in the post I put in the original thread referenced about this RS engine. I should have said "transmission oil pump" not cooler when discussing the unique 915 used in the RS through mid-March production.

Only the RSR model used both an oil pump and cooler in the 915. The coolers in those models are located in the front left fender and look exactly like the engine oil cooler with lines running down the left side of the car.

Anyway, for reference here is a photo showing the oil pump housing on the front of the 915/08 transmission. Since the stamped numbers seem to missing on your transmission this would another clue to look for to determine if you have this type of 915.

[fryardds]

Oh, FWIW I agree with Ratbox. The engine serial number stampings are correct for an RS engine. You have the correct case for sure. What about the injection system for the engine? Does it have a 019 MFI pump? Thanks.
