930 Turbo Carrera

When I was 10 years old, my mom bought me a Porsche booklet at the mall to keep me quiet. I still have it. The image of a 930, black on black, has been seared into my memory since that day. Looking at the above images, it's immediately the black car that holds my attention.

All of the generations are great looking cars, and remarkable for their era. Just funny how to me, a Porsche Turbo has to be black. For the same reason, an RS car has to be a flamboyant colour. My preferences were ingrained at a very early age.

 

So I have a US 930 with a 930/50 engine in it- not correct to car. Anyone know what these are worth? Obviously to owner a the matching number a lot - I'll assume car is gone. I believe they built 157 ROW 930's in 1976 with these motors.

Your right I do have some that I kept in preference to selling some of the stock ones. If done well, like by Andial ( brand now owned by PCNA ) Porsche Kremer ( 935 builder for group 5 from 78-83 for credited to Porsche wins ) Holcombe (Mode) and others that were in Porsche's good graces to build with their race parts. They are very reliable and easy to work on and are scintillating to drive. I'm glad the showroom stock ones are very popular now and continue to gain in value sooner than the others as the stock ones are the ones that I will sell first. I'll probably keep one for a touchstone. It also helps to have 3 stations close by that sell 112 leaded for the big HP ones.

 

We might be talking about two instead of three scenarios. A poorly Modded 930 can be a PITA so I do not disagree with you. However many stock early 930's suffered from the restrictive emissions that caused overheating and head stud failure. Over half I have owned all with good service and most with around 1K miles a year or less had some problems due to restrictions from US regulations. In subsequent years Porsche themselves updated with better functioning parts ( better oil cooling etc). However some 930 were built by real pros that worked with Porsche competition cars in the day. Andial, ( recently added to the Porsche brand ) Kremer, Jarvis, Holcombe ( Mode) Alan Johnson , Canepa, RUF, that put together some nice street and competition cars. Porsche did not mind claiming the race wins from their racing success. So 930s that are not showroom with do dads that were not designed for it could be a different category than ones that used parts and technology from Porsche Motorsports own parts department and racing development with the 930 project and 934-935 to make them Handle, stop and go faster and be stronger. Of course if it was built with local speed shop parts and do dads, now that ,to me is a different situation. I also have driven many 930s both stock and sensibly modded for tens of thousands of miles with a only a few limping home rides, for over 20 years including cross country. If your client base wants strictly showroom stock that is for sure the best way to go for most. I started that way decades ago and most will never step into my world of appreciation for driving, light competitive ( D E ) racing ( and concours ) of Kremer, Norwood, Holcombe, Andial, AJ etc built cars. And yes I would like to own one of the few 934s that were built to be street driven however I would have to give up most of my 930s to get one if one were to become available.

 

Joe – I’ve looked all through my references and not found much on 934 gear ratios but it makes sense that they changed depending upon the track. FIA Appendix J for Group 4 allowed manufactures to homologate three sets of “recognised” gearbox ratios and two final drives. To take advantage of this for the required 400 production cars for homologation, Porsche used the production 930/30 and 930/32 transmission & gear ratios (15 inch Fuchs with standard Dunlop/Pirelli CN36 or low profile Pirelli P7 tires) and two final drives. An article in the April 1976 Christophorus article mentions 934 gear ratios: “Since competition use had been considered when the four speed gearbox was designed, no major modifications were necessary and the same is true of the powertrain. Gears and synchronization are identical to the road car while two further gear sets and three rear axle ratio alternatives are offered.” Christophorus photo captions: “A glimpse of part of the Zuffenhausen sports shop”; “A sporting spares department ensures parts supply. The widely loved Mrs. Baer (middle) keeps the sport drivers happy.”

Anyone know about these numbers? The re builder thought race numbers. The differential also has larger tapered bearings than stock, dated 8-76. Also the trans number is different style than my other 76-77 short bell housings ( with 3 stars ) and different Porsche part numbered gears 1st-4th. It was in a turbo race car before sitting on the shelf many years and I now have it for a spare. Not that easy to read trans # any more, as in photo.

Peter just dropped off 1976 #470 after a year's worth of refresh. Totally rebuilt engine/trans, suspension refresh, massive cleaning, replating, buffing. Correct working Blaubpunkt Bamberg, original paint, OEM replacement parts from Porsche Classic like sun visors, door pulls, rubber grommets etc etc. Thanks to iDart of great suggestion of period correct 8/9" 15" diam RS wheels, which look amazing with 225/285 vintage Michelin racing tires. Too much Power's Irish tonight to go for a drive but tomorrow AM...
Everything works but rear wiper motor and the Hirschmann... ideas appreciated!

Tony, I have not seen three stars before but it probably is a racecar transmission (934, 935?). It’s a bummer 930 transmission numbers are on a very low point and subject to abrasion. When I first bought my ’75, I stretched under my car and took a blind shot with my Canon ELF in macro mode/flash and was happy to see the number was still on my transmission.

 

Looks great - congratulations. I’ve got my stock 8/7 inch Fuchs back on my car for the winter but I really like the 9/8’s. The RS/RSR 15 inch Fuchs are iconic and it’s very cool how they fit nicely on the 3-liter Turbos. I just found some Pirelli CN36 215 60 15 tires and I'll bet fitting these (with CN36 185 70 15's on the front) on the 8/7 inch Fuchs. My '75 was originally delivered with optional Pirelli CN36 tires.

 

That's a beauty!

 

Thanks for the reply. Also the R at the end of 930 301 101 OR and the following symbol different than the shop that inspected it could find any ID info on.

Very nice indeed, enjoy!

 

Here are a few 1970s PCA Zone 8 advertisements featuring cartoons and drawings of the 3-liter 930 Turbo.

My '75 Turbo was originally delivered with 930 safety script and Gazelle wheels. The wheels will be Gazelle (gold) for sure, but I have not yet decided on the 930 script. Should look something like this. Has anyone seen pics of this combo back in the days? And if so, would the script on the side have been like this?

I’ve never seen the 930 Turbo safety script but the 911 version was offered as an option. The Porsche script on the sides was a separate option for 1975 Turbos. Jose’s salmon metallic 1975 Turbo was originally delivered with a 911 hood decal. Here's a period photo with the original owner in Hong Kong in the 1970s.

From the Japanese book “The 1978 Porsche” features this Emerald Green Metallic 930 Turbo. The gold Fuchs look great with this color.

Also note the typical Japanese-style mirrors fitted in 1974-1975 model year on the orange 911. Some early Japanese delivered 930s also featured this mirror.

That number is close to the 934 Getriebgehäuse number from the Ersatzteilekatalog, which is 930 301 101 10. But not the same… perhaps a 935 number? (Sorry, I don't have the book for those.)

 

There was a selection of 934 ratios, per the Ersatzteilekatalog.
1st: 16:36, 18:33, 20:32
2nd: 23:30, 24:29, 25:28
3rd: 26:26, 28:26, 28:25
4th: 30:22, 32:22, 32:21

 

Interesting – those are the same ratios listed in FIA Nr. 645 although the stock production turbo 930/30/32 transmission only had the following ratios:

1st: 16:36
2nd: 23:30
3rd: 28.25
4th: 32:21

The final drive on the 930/30 was 9/38 (215/60 VR 15 tires) and for the 930/32 was 9/36 (225/50 VR 15 Pirelli P7s).

 

I hadn't noticed that the mirrors were different in the emerald green turbo photo.

Here’s some period factory literature that shows the optional 911 hood stripes and Porsche negative lettering side script.

Thanks, That info is what the trans builder thought either 934 or 935 as none of the numbers aligned with stock numbers. I do have the gear number ratios from all 4 gears so I can see if they match up with the post on optional ratios.

 

Thanks! The Kardex says 'Sicherheitsbemahlung', but not exactly which one, so I'll go for the gold side-decals then. Should look nice on my black car with the Gazelle wheels.

Note that this particular Emerald Green Metallic 930 (in post 3141) also has the earlier style tail as opposed to the later style which appeared in 78.

 

Hello,

this evening I "detected" a apart in my boot in my 930 US that is missing in my 930 ROW.

Is this part in your versions as well?

Is this a fortifying upgrade?

Thanx for any hints.

PS: this is a US 930, the other one I compare to is an ROW one.
