These are some of the questions I posed to Porsche that have not been adequately answered. In my research, the Slant Nose verbiage on the COA didn't happen until 1986... Porsche has been very vague with me - not giving definitive answers either way. Same thing with the headlights, they just said that in the early stages, they didn't use consistent parts for all of the SW cars and that it is not uncommon to see variations between the builds. Again, not confirming or denying if this car was actually built at the factory. I do know that the conversion was done in Germany in 1982 but have not found out what other shops, if any, were performing these conversions in Germany other than Werks I. Unfortunately, the original owner is no longer around to answer where he had the car built.

STRAIGHT FROM PORSCHE COA : VIN WP0ZZZ93ZCS000332 does not have the slant nose option at the time of production. We only list zero's on COA's, not O's. The option this COA refers to as a slant nose is actually Equipment for West Germany.

No, there is no slant nose option on this vehicle. The option number 499 refers to Equipment for West Germany. This COA reflects that option incorrectly as a slant nose.

The COA posted is a FAKE. Someone removed / photoshopped 499 (Equipment for West Germany) option and put Slant nose.

FAKE FAKE FAKE FAKE!

Thank you, turbotoo.
My VIN does not have an O, only zeroes. I have the actual physical COA in my possession, not a digital copy that has been photoshopped or otherwise altered. I own and have owned many Porsches and this COA is exactly the same as my others. I verified with Porsche NA and Porsche that they have the slant nose option listed in this car's records - I have not verified what information they had to include that as an option as I have no supporting paperwork. The COA correctly lists Equipment for Germany as an option.
Of course the car does not have the slant nose option at the time of production as that wasn't an option to list at time of production. We all know that the only slant nose cars came through the Special Wishes program. No cars that I have found have the slant nose option in production prior to 1986. The COA is not from 1982 - it was issued at some time after and obviously Porsche had enough information, either from the then-current owner or in their own records, to add Slant Nose to the options list. This is the most perplexing thing about this car...

I in no way want to portray this car as something it's not as I am trying to sell it. I have a good reputation in my small circle of SoCal car-folk acquaintances and would like to keep that. I have, however, spent many hours researching this and trying to get the answers about this car's provenance and there is no 10-minute definitive answer.

I have found that whether or not this car was converted to slant nose in Werks I, it was done in Germany in 1982 and I have not found information about any other shops that were performing these conversions in Germany at that time. The conversion is very well-done and the car is solid and beautiful and has passed the test of time.

OK I went through this same headache when I had my '83 popup slantnose.

Here's the thing...whether or not the old COA is fake doesn't matter at all! It isn't worth the paper it's written on when it comes to Werk 1 slantnoses up to 1986. PCNA had no access to Werk 1 records until very recently when they were found at the factory. This was soon after I sold my 1983. Marc Noack at Porsche Classic also has access to these records and if he verified it was a slantnose then I'd trust him over some old COA.

What inlinesix needs to do is call the PCNA COA department and tell them the COA he has is in error, as the 499 code does not match the "slantnose" option, but is a code for German market.
Specifically ask that they check with Porsche Classic in Germany to determine if it was done in house as this is not something they normally do. I think it is Marc who does this for them on request, he will provide the correct info, and boom they will mail you a correct COA. They should do this for free due to their code error.

Yes this is a delay and a hassle, but if you want 6 figures for a car like this, very necessary! I would also print the email from Marc as further proof. Without doing this, the collectors will always be in doubt with that incorrect slant nose code on an old COA.

As for a 1982 Werk 1 slant having popups AND fender gills? Highly unlikely...they were added as an option in 1984. I have not ever seen a 1983 or older slant with popups and gills. All 1983s with popups (they did still make hammerheads too) I've seen are flat behind the headlamps, and all 1982 and older I've seen are the hammerhead design with no popups.

I compiled all my research into a .pdf which has a ton of details about these special cars. It's now on version 1.2

Here's my '83 for comparison...I sure do miss her.

It's also very suspect to me that the car seems to have zero other Sonderwunsch options. That is VERY uncommon as people who spent the coin for the conversion wanted custom options. Perhaps it was theft recovered and/or was converted to the newer gilled look later in the 80s to modernize it?

Compare my rear fender vents to his...the vent opening should follow the wheel opening exactly. Either it's been seriously molested or it's not a factory slant.

Thank you G60SC for the helpful posts!
Love your old car - what a beauty!

[G60SuperCharger]

Thanks! I love the color on yours...is that chiffon?

One more thing I thought of. I was able to obtain a copy of the EPA certification when my car was imported in 1985. They keep records of these things and will mail you a copy! In my photo link the car was noted as a "935S" which indicated it was a slantnose when imported. With these cars, the more evidence the better! I'd try to get a copy.

Awesome and thanks again for the great info! I have the BAR certification but not the EPA paper so will get that and see how it's listed.

Yes mine's Chiffon.

One thing that is true.. in the early days 80- roughly 83, it is very hard to say what was included from the factory given what an owner or whomever ordered the car specified on their wish list. Many of the items used even for production 930's were sourced from other models... and some pieces were even out-sourced. Paint to sample was also a very hot item at the time

For instance, the single motor and related mechanism for the pop-up headlights is actually from the 928.. and we know that in Europe, the 928 arrived in 82.

G60SC.. the center console you show in your car is actually a DP or Kremer unit.. and Porsche and both these firms did a lot of work together in those days. The IC looks to be a Garretson or PowerHaus full bay.. something that it would have gotten after it reached these shores.

Again, in the early days of the slant, you pretty much could have gotten whatever you wanted to pay for.

Onboost, this is exactly the answer that Porsche and Marc gave me when I asked about the headlights on my car. Again, not confirming or denying anything.... 🤦🏼*♂️

Thought I'd Chime in. I have posted pics of my "unmolested" 82 Hammerhead. Getting any HARD evidence on these one-offs is nearly impossible. I have posted of my issues with mine. The original owner is still alive and we are still searching for more paperwork. I was told by Porsche classics division reps just what onboost said, it was the wild-west at Werks I. Maybe build sheets some day, who knows.
Mine was imported specifically under a "racing only" title. Due to headlight issues, mainly, it was not considered "street legal" by US DOT. I personally have never seen or heard of one with dual pop-ups. The vents are a completely different issue. Sorry, in my research and opinion, it may be factory but added after (possibly by the factory) the model 82 year.
Yes, I have gotten it from more than one source at Porsche that only 10 were built. Again, mine was originally ordered to race with the thought that the hammerhead added some aerodynamic edge to the car. Other than the hammerhead, it had very little in the way of options as it was going to be stripped to track. Luckily, never got to the track!
Yes, again. Parts were sourced from other places than WERKS I. Speaking to the factory reps in Germany, I was told the valance was fabricated off-site, one at a time. These are fiberglass and Porsche did not have the factory set-up to do this work (at least in 82). This caused a huge backup in the order to delivery time. I've gotten various answers as to how the fenders were fabricated. The 2 most popular answers: 1-"coke" bottles were cut out, new metal welding in, polished then fitted to the car, 2-(my most likely thought)that each set had to be hand fabricated from a "buck" as they made so few they didn't have a model to "stamp" the sheet metal. I think this as the profile is much wider at the bumper than a stock 930. With the amount of work involved to cut, weld, finish...would be easier to hand hammer as so few were made. This was a VERY expensive option. From order to delivery, mine took 9 months to fabricate.
Just my opinion. I know the issues with getting hard documentation. This one would be WAY ahead of the 82 I have as the vents came along later and the pop-ups don't make sense. You can look back to the photo I posted of mine, dual headlights both sides. Porsche reps confirmed in writing that this is how the 82 was built. Certainly not saying not factory, but it's going to have to be documented out the wazoo for me to believe it. Good Luck in getting your paperwork, you'll need it!!

Apologies for this being my first post, but I've registered for this forum specifically for this thread.
If a 930 turbo was sent to Porsche between 1987 and 1990, for upgrades would it only go to Werke 1 and Zuffenhausen under the Special Wishes Program? What if a car was getting engine modifications using 934/935 parts? Would this involve the Weissach Motorsport guys?
I'm right in thinking that Weissach dealt with customer race car repair/ restoration, does anyone know if specific price lists exsist like the special wishes catalogue?

Apologies if I'm in the wrong area, there is just a lot of great info in this thread, please redirect me if there is a more suitable topic?

My understanding is that Weissach is utilized strictly for research and development for Porsche and other manufacturers (under contract). My visit to the complex in 1986 revealed extensive work being done on the 959 and future C2 and C4 vehicles (no photos permitted of course).
Any repairs and/or modifications to customer cars (incl. race cars) were done at Werke1 in Zuffenhausen. Any options requested through the Special Wishes Programme would be scheduled and completed at the repair facility (Werke1).

Cool, thanks for the reply. I spoke to someone who was also there during the 80s, someone who worked there, and he said the same, but did note than even a road car would require some kind of Weissach involvement when the subject of 934/935 parts is mentioned, as he said customer race cars made their way to Weissach not Zuffenhausen . Is there a resource available somewhere with more detail on Weissach/special wishes/Werke 1 etc?

[billswim]

Interesting thread. Just found it. Here's a shot of mine. '88 Targa genuine 505 option car. Might be for sale. I guess its sort of a unicorn. Didn't realize that when I got it.

[berponte]

Please, can someone bring some light into this 88, targa, slant??
I agreed with the owner, very rare indeed. how many they built??

[Cobalt]

According to Norbert and Franz who have done a masterful job documenting all Porsche air cooled turbos in their book. "Porsche 911 turbo Air-cooled years 1975-1998 there were 9 88 turbo targas made with option 505 all came to the US.

9 more were made and imported to the US and Canada in 89.

I would say they are quite rare and valuable.

Hi every one, my name is Stuart and live just south of Johannesburg, South Africa.
I have owned one of only 2 Special wishes cars in South Africa for 20 years.
This car is very special and has featured in a few TV adds years ago for a local petrol company called Sasol.
It has a very powerful engine from Porsche that produces 400Hp. I had it tested on a dyno at M&R motors (Porsche service specialist in JHB) and it put out 389hp on the back wheels. I have a list of the options that were done and the badge on the glove compartment of the guy that the car was built for.
Can any one help me identify and get me more info on what was done by the factory. Werk 1 looks like you are very knowledgeable on the abbreviations.
Oh, it is a 1984 model and is stock standard form the factory.

Thanks so much. Is there anyway to find out more about the upgrades done to the engine?
