That motor is the biggest piece of crap Porsche ever built...but being the nice guy I am I'll buy it from you for $50.

It's actually a 73RS 2.7 The motor that came in a real Carrera RS.

SCOOOOOOORE!!!!!!!!

But wait there's more!!!

The story gets even better. That motor used to belong to one of the rare factory Carrera RS lightweight cars. In fact it was VIN# 9113601423 Option 471(lightweight) in Light Ivory with Blue Carrera graphics. Originally built in 6/73 and was first delivered to Italy.

My guess is that the original car might have met it's demise in a race.

You should post this motor on the Early S Registry board as well as possibly contacting Jeff Starkey who wrote Porsche 911 R-RS-RSR just incase the car survived. The owner would surely make it worth your while to return the motor to the original car.

Wow, makes you wonder what kind of duty that motor's been seeing all these years. Probably pushing a GruppeB(astard) car.

All the makings of a happy reunion of legends here - and a handsome profit to boot!

Keep us posted.

Whoa - wait a minute, what's the VIN of your "project"???

The engine was in a Targa Body Vin # 9114310194 and has only 40,000 miles on it. This was an amazing find. Any ideas on a direction here are appreciated.

I would sell the engine to an RS owner looking for an original or a spare. Then buy another one (you can probably sell it and buy a 3.2, if you find the right person). Putting it into a plain vanilla targa seems a bit of a waste. Does it have all of the MFI goodies on top?

The motor is comlpete- it was removed by the previous owner due to an idling problem and then never finished. How anyone could just walk away from it leaves me perplexed. I would sell it to assist in an original RS restoration. Any ideas on the idling difficulty on this paticular motor?

That's unusual. Usually you would fix an idling problem with the motor installed so you can adjust it while it runs.

Do you have a digital camera? That way you could take a picture of the motor so we could verify the induction setup.

The 2.7RS is a great motor. Arguably one of Porsches best. If a search doesn't turn up the original car then just install it and enjoy. It'll be a blast.

Here's some photos of the different inductions. Yours should look like the first photo. A 2.7RS.

The second photo is a 67'S with carbs.(thanks Shawn

I have some pics and will post them on Friday-things here are a chaotic due to the blackout in the east. This brings the Cal problems into perspective.

You could probably trade your motor for a nice 3.6 varioram if you find the right buyer.

Here's some pics of that engine. I decided not to proceed with the restoration until I can accurately identify it--so its a little dirty.

Thanks Mucho Guys

This is not an RS with MFI, this is a regular ~74 CIS engine!

Groesbeck Hurricane · 08-15-2003, 09:54 AM

Could not have somebody put the CIS on because they didn't know what they were doing? If the serial number is correctly typed and accurately portrayed in Bobby's reference material I would try and get the motor back to where it was out of the factory.

JSDSKI · 02:08 AM

Anybody checked the engine type number on the fan housing? 911/83 = RS. Just from pix - tref is on the money - it has a CIS FI system but on a green shroud (usually means E) engine? Misread serial number? Installing a CIS induction system on a MFI cammed engine would creat a serious tuning nightmare. What is the distributor type number?

printpro · 08-16-2003, 05:56 PM

First off, thanks to all who are helping solve this mystery.

The fan shroud Id tag is missing which is proving to be a major problem in this quest. As for the distributor it is a Bosch #
0 231 184 001 JFUD6.

Some research has provided some info that brings perspective on this motor. The original owner was a US strategic bomber pilot who was stationed in Germany and the UK. When not threatening the ex communist states of Europe, he was building and racing Porches. Someone who knew him claims he had direct factory contacts due to location- yes I am attempting to contact him for some help on specifics. It may come down to an actual measurements of all the internal components to see what I have here. A previous owner ( not the original) claims to have had the Targa body over 150mph in Ontario several times with little difficulty-- is this possible with a "common 74 cis?? Although it had a very healthy top end speed it never idled hence the engine removal. What a mess. Please pass along any thoughts and I will post a picture of that engine #.

Well, if it is really a MFI converted to CIS that would explain why it refuses to idle.

JSDSKI · 01:10 PM

0 231 184 001 - this part number is listed with Bosch as a 74 911 distributor but doesn't provide the model. It doesn't list the JFUD6. But this looks like a standard CIS set up with that injector position.

I think you need to recheck that serial number...
