When the now famous Porsche 935 'Moby Dick' came out in 1978, it sported a new front design which eliminated the 911's round headlights, forming a totally flat hood 'slant nose' or slope nose. In 1981 Porsche offered a Slant Nose conversion in Europe under the Exclusive label in Werks 1.

Since 1981 the flat noses had been built by the Zuffenhausen repair departement. But only in 1987 the flat nose was officialy listed as an option for the Turbo. Only very few were built by the factory. About 80% of the flat noses are 'fake'. Early flat noses had the headlights mounted in the front wing, while later models were equiped with folding headlights. Behind the bumper and additional oil-cooler was placed. A total 236 were built between 1982 and 1987.

It wasn't until 1987 for the US market that the Porsche factory began offering the Slant Nose body option to the 930 Turbo. Porsche factory began offering the Slant Nose body option to the 930 Turbo. The Porsche 930S is the 930 Turbo Slant Nose, with the option codes M505-Slant Nose (USA) or M506-Slant Nose (RoW) 'Rest of the World'. Generally, the factory built Slant Nose configurations were built at twice the price of the car. These cars now are worth much more than the normal body style, while the aftermarket Slant Nose cars are worth a little less than the factory Slant Nose price.

The factory Slant Nose option was an additional $29,500 on the $85,000 Turbo 930 base price before options. Making the car list over $126,000 in 1987.

Flachbau is a very rare edition of the exotic Porsche 930S Turbo 3.3 from the actual Porsche factory Werks 1. The Porsche 930S, Turbo 930 Slant Nose is the worlds greatest exotic sports car. These are very rare exotic sports cars; with less than 300 produced for the US market over its lifetime.

During the the 80's Porsche produced the 930S Turbo 3.3 as a limited and exclusive model based on 935 Moby Dick racer. The cars were modified by a special department of the factory to remind the public of the look and the success of the 935 'Moby Dick' race car. With its striking looks and its improved engine, the 930S turbo 3.3 Flachbau is really exciting to drive and the accelerations of the turbocharged engine will plant you firmly into the seat.

The 930S is a very rare car since less than 500 of these models were ever manufactured in the world. Between 1987 to 1989 a total of 300 cars were sent to the US. 930 / 911 Turbo Body w/factory slant nose production numbers from Porsche. From 1981 through 1986 under the Exclusive label in Werks I a total of 262 cars were built. Between 40 and 60 930S slant nose cars per year.

In 1987 through 1989 Porsche made both the Targa and a Cabriolet available as a Turbo model as well as the traditional 911 Turbo coupes, in addition to the standard production cars. Porsche has been doing custom work for their customers in Europe at their customer service department in Werks I for several years now. A few years ago they started a program that they call the "Sonderwunsche-Programm" (Special Wishes Program) where they offered their customers a catalog of conversions, modifications and customizing work. Starting with the slant nose body option PCNA is starting to offer a version of this program to their US customers as the "Porsche Exclusive Program".

All of the original Slant Nose Conversions built before 1987 were built by Werks 1 by their Special Wishes program. You cannot tell these cars by their VIN number. You can ask Porsche and it is possible that they can tell you. After 1987 the Slant Nose version was manufactured in production under option number A 505. The M505 is a USA/Canada version of the 930 Turbo based on the body types coupe, Targa and Convertible and M506-Slant Nose is the (RoW) or 'Rest of the World' version.

M505 and M506 -- cars have the following conversions: Slant nose with concealed headlights Wheel house vents (Louvers) in front fenders Entrance trim panels (boxed rockers) left and right Air inlet ducts (brake ducts) with connectors in rear fenders Oil cooler with blower in right rear air inlet duct.

Because these cars are built and modified by Porsche they are able to keep their complete new cars warranty. This series of cars marked the first time that the factory-modified cars have been made available to US customers through the factory organization and PCNA. Prior to this first series built in 1987 all slope nose conversions in the US were either grey market cars or cars that were converted by an independent body shop or tuning firm as the specialty shops are called in Europe. In either case these cars were not covered by the factory warranties in the United States.

930S Turbo Slant Nose US Version (M505)

In 1981 through 1986 you cannot tell from the VIN number if car came from the factory as a slant nose or was converted. You can actually get the build codes or order a certificate of authenticity from Porsche. Several things can identify most conversions. The easiest is, none of the Porsche slant nose setups ran square headlights or separate motors in each bucket. The original headlights were more or less from a 944, along with the shrouds, and the motor. A single motor inside the trunk drove both motors via a large rod. Much like the 944-headlight setup. Most of the aftermarket versions are not this way and even if they have the round headlights the buckets are sealed with separate motors in each bucket. None of the conversions are known to have a replica of the single factory motor headlights. Most of the "good" builders of these aftermarket parts are long gone. The major players in the game were DP, Goldencoach works, VIP to name a few. The option codes will tell you if it was an slant option, unless it was a Special Werks car with the version I fenders. Total number ever made 600.

930S changes included the air inlet ducts (brake ducts) with connectors in rear fenders for a oil cooler with blower in right rear air inlet duct. The original setup kept the same bumper assembly and accordion trim, however, on 930S production cars, the lower front valance on a factory built slope nose was made from fiberglass. The factory panel on a slope nose had opening on both sides for flush mounted driving/fog lights as well as an opening for a front mounted oil cooler as well. It was painted the same color as the rest of the body and had a smooth finish to it. This differed from other 911s and 930s that had a rough texture on them due to the stone guard that was applied to them, and then painted to match the body.

The slope nose "option" (which does not show in the VIN) was not offered by Porsche in the US until 1987, so the earlier slope nose cars would have been aftermarket conversions of production cars or European slope nose cars imported into the US. You can detect a RoW (Rest of the World) car from a US conversion car by the VIN.

930-T2.jpg


A 1986 or earlier model year RoW (Rest of the World, incl. Euro), would have a 17 digit vehicle identification number (VIN) and the number would not be in the correct format. For example, a US 1984 Targa would be WPOEB091ES#16XXXX, (the last four X's are the sequential manufacturing number). The 1984 model year is designated by the letter, "E." in the US. The equivalent ROW 1984 Targa would have been WPOZZZ91ZES14XXXX.

Finally, a good thing to check is the engine type number, which is stamped in the engine case on the right hand side of the crankcase by the blower inlet near the oil pressure sender. There is both an engine serial number there as well as the engine type number. The 1984 US Carrera would be engine type 930/21 and the ROW engine type would be 930/20. 1984 US engine serial numbers would be 64EXXXXX (E=1984, X is sequential number) while RoW engine numbers would be 63EXXXXX.

930S Turbo Slant Nose RoW Version (M506)

The RoW cars produced with option code M506 (Rest of World factory slant nose option). The RoW gray market slant nose cars were imported into the US either by an exemption to the emission controls due the their rarity and a collectable status or by converting them by adding the emission equipment.

These cars are very rare, with less than 40 manufactured per year between 1981 and 1989. For example, in 1987 there were only 37 cars produced with option code M506 (Rest of World factory slant nose option) Special wish conversion made that year. In addition this was the first year for the official factory option for the US, which started in March of 1987. If you found one of these 1987 M506 cars you would be looking at only one of 37 cars made.

It is very hard to tell the difference between an original factory Slant, and an after market conversion. Here are a few guidelines to go by when diagnosing the 911:

CHARACTERISTICS OF AN AFTER MARKET JOB:

1) 4 studs at the four corners on the underside of the louvers
2) Splash guards attached to the 4 studs
3) Imperfect headlight door jambs
4) Japanese headlight motors
5) Wiring to lighting
6) Welded light buckets that intrude onto the wheel hose skirts
7) Evident mig-welding of 3 separate insert panels to factory fender
8 ) Windshield washer reservoir in left fender changed (or cut down)
9) Dents in the battery area of the shirt to fit under buckets
10) Cut out of the bumper shock support to fit buckets
11) Composite or plastic rear vent slats
12) No octane sticker on back of fabricated gas lid door


CHARACTERISTICS OF THE REAL DEAL:

1) Wood rear vent slats
2) Dual oil cooler in rear qtr vents with screens
3) Jack extensions extended factory welded to rockers
4) Factory stamped part number on rocker panels
5) Two piece rear vent hole
6) Exact die cuts in the corners of louvers
