Wow! This is a fantastic thread on the slantnose! Lots of great info! Scans of the original brochures, documents and articles were very interesting to see! Thanks everyone for the input! There is a very high level of passion for these slantnose cars!

I am considering the purchase of a 1983 which the owner claims to be a factory slant. Before I make the drive to physically look at the car, I would like to find out what details I should be looking for to identify that this is in fact an original. I've always loved these slantnoses, but I really don't know much about the authenticity aspect or what to look for. I have a few questions for all of you if you don't mind.

1) From what I understand, there should be only one headlight motor which is centrally mounted right behind the front bumper in the trunk? From pictures, it looks like a fairly complicated linkage system going to each light. If the car has separate headlight motors.......fake?

2) Are the actual headlights on these cars always round? If the car has square headlights......that would indicate a conversion/aftermarket parts?

3) From what I understand, there are unique serial numbers on the slantnose front end parts. True? Where exactly would I be able to see these numbers?

4) I've also read that there are some custom moulded plastic parts that are in the front trunk. Would anybody have some pictures of these parts or description on what these look like?

5) From what I understand, the slantnose was basically an option on a "normal" 930. Would the VIN be able to identify an original slant, or will it only designate a regular 930?

6) I've also read that there are some wooden slats or parts for the cooling vents in the rear quarter panels? What exactly should I be looking for here?

7) What else should I be looking for on this car to verify? Any advice, tips, suggestions would be greatly appreciated!

With any luck, I hope to be a part of this passionate group of slantnose owners one day!

Thanks very much in advance!

1) From what I understand, there should be only one headlight motor which is centrally mounted right behind the front bumper in the trunk? From pictures, it looks like a fairly complicated linkage system going to each light. If the car has separate headlight motors.......fake?

That is correct. The headlight motor is cylindrical in shape with a rubber boot on top of it. Quite visible when you open up the front bonnet, right below the bonnet latch.

2) Are the actual headlights on these cars always round? If the car has square headlights......that would indicate a conversion/aftermarket parts?

Yes, always round.

3) From what I understand, there are unique serial numbers on the slantnose front end parts. True? Where exactly would I be able to see these numbers?

Not necessarily part numbers, but stampings Porsche uses as part of their manufacturing process. Unfortunately, they may not always be visible since they may be painted over.

4) I've also read that there are some custom moulded plastic parts that are in the front trunk. Would anybody have some pictures of these parts or description on what these look like?

They are, from what I've seen, fiberglass. See photo below.

5) From what I understand, the slantnose was basically an option on a "normal" 930. Would the VIN be able to identify an original slant, or will it only designate a regular 930?

Before Model Year 1987, there is no way to identify slants from VIN.

6) I've also read that there are some wooden slats or parts for the cooling vents in the rear quarter panels? What exactly should I be looking for here?

This is, I believe, somewhat of an urban myth. Wooden slats may have been on the early slants, '81 and '82, but all the ones I've seen are composite plastics.

7) What else should I be looking for on this car to verify? Any advice, tips, suggestions would be greatly appreciated!

Check the contour of the rear brake ducts. The outer edge on the factory cars will always follow the contour of the wheel lip. In other words, the line of the brake duct is always parallel with the wheel well lip. See photo below.
The jacking point at the rocker panel will have an extension of the existing tube with an additional tube welded in at 45 degrees to the frame.
Then there's the famous windshield washer bottle that is tucked underneath the driver's side headlight, visible only by removing splash panel in wheelwell. See photo below.

With any luck, I hope to be a part of this passionate group of slantnose owners one day!

Thanks very much in advance!

Hi Ted,

Here is a photo of the adjustable boost control, this was mounted by factory. Just checked with my mechanic and boost dial actually runs to 1.2 bar, probably good for 425 bhp or thereabouts...its all happening very quick. Will post a video in due course

Hi Werk 1,

I noted you collect any Sonderwunsch information, will include another post on the original flachbau brochure which shows how to build M505 slantnose version. It's in the German langauge, sure soemone can help translate for you if you would like the 32 page brochure let me know.

Rgds Kenny

Hi kycarguy 935,

Here you go guys, this was the orginal 1987 flachbau turbo (slantnose) M505 brochure. This is the first half with another post to follow with remainder.

You will need some help translating from German... refer to last page for technical specifications with reference to 330 bhp engine.

Hope this is useful for the collection

Rgds Kenny

Thanks very much WERK I. Very helpful info! After a bit more verifying on the phone, it turns out that the car is just a "regular" 930 with an aftermarket slant conversion kit. Fenders are steel, but aftermarket. Thanks again though........I'm learning a lot about these from this forum!

Thanks Kenny1961 for posting up pics of your M505 brochure. That was very interesting to look at!

I have registered 930Sregistry.com now to get going on a website. I still have a lot of work ahead of me and trying to figure out everything.

The good news is that it is started now and I will be working toward getting something up and workable as soon as possible.

Thanks for all of the positive influence to help me get this started. Thanks also to Bill for some good ideas.

Will update when I have more to share.

I have been real busy this last couple of weeks and haven't had time to find a web host. I asked a few of the IT guys at work but haven't heard anything back from them yet.

Thanks for checking. Will update when I have some new news.

Hey don't recall if you answered this before but what is the scope you are considering for the registry?

Just US M505 cars? US and Euro? pre'87 factory cars too? Or everything including conversions? Just wondering.....

Again if you need any help let me know........

Hi Kilodawg,

I would like to include any and all factory made 930S slant nose cars.

I don't think I would include the modified cars after they left the factory because there is no real way to track them.

I think the best thing to do for the 930S community is to register what we know or Porsche would possibly help on.

I have a contact in Europe now that has access to a lot of information on these cars but not sure how much he will be able to share yet.

Thanks for the offer of help. I will probably need it once it progresses a little further.
