Two Porsche 930 Turbo Slant Nose 911 for sale; one real and one a conversion. They are recent auctions on Bring-a-Trailer (BAT). The “real” 930 Turbo Slant Nose sale is ended and the car was a no-sale at $103,000 versus the modified conversion currently bid to $45,000 with two days to go. Final sale will probably be in the $80,000 range. The Sports Car Market Price Guide reports a median price for this model of $193,000.
According to the Porsche Production Specifications Certificate the no-sale 1982 Slant Nose is a real Special Wishes Department conversion. It was one of 42 that was built that year by Porsche. so it is easy to understand why this car was a no-sale. This is a clean, unmodified official Slant Nose, so the only reason for the no-sale seems to be that the buyers were just not looking at BAT. This car may need to go to one of the major Collector Car Auction Houses, such as RM Sotheby’s, Goodings or Bonhams to bring the $200,000 this car is valued at.
Looking at the other Porsche Turbo Slant Nose currently on auction with BAT, it is questionable whether it is a “real” Porsche Special Wishes Slant Nose or an Aftermarket conversion. Based on the price disparity between a Porsche conversion and an Aftermarket conversion, it would be worth the owner’s time and money to do the research and verify its origin. Commentators on BAT indicate that it may be a real Porsche Slant Nose, but without research it is an unknown about the vehicle. It has also been modified with brakes, wheels, the intercooler and exhaust and seats. The slant nose conversion is a steel slant nose with black side strakes and pop-up headlights.
The 1982 features headlights in the bumper. Porsche started conversions with this headlight spec but later models moved to the pop-up headlights as seen on the 1984 model on offer.
A knowledgable owner of a similar 1984 Porsche Special Wishes verified 930 Turbo Slant Nose ,@wdowmaker930, weighs in on BAT with why this 1984 might be an original Slant Nose and might be a bargain in hiding. Further down is @wdowmaker930’s commentary about how to confirm originality.
Air Brigade Value Opinion
If Air Brigade had $100,000 to buy another Porsche, the 1984 Slant Nose on offer right now on BAT would be one to investigate further and gamble that it is a real Porsche Special Wishes Slant Nose. If it is real, you could invest to return it to original and still not be underwater based on the the $200,000 market value.
History of the Porsche 930 Turbo Slant Nose from Wikipedia
Kremer Racing had originally begun offering conversion kits for 930 Turbo models which included front bodywork like the famous 935 race car in 1981.
In 1982, Tag Heuer co-owner Mansour Ojjeh commissioned Porsche to develop a road-legal version of the 935 race car. The final product was developed using a body shell of the 930 and fitting fabricated 935 body panels to it. The one-off also had the suspension and brakes shared with the 935 race car. Other special features of the car included special paintwork called Brilliant Red by the manufacturer, BBS wheels and the use of the 3.3-liter turbocharged flat-6 engine of the 934 race car. The car proved very popular among enthusiasts and prospective buyers began to demand a similar car as a factory offering. Porsche offered a "Flachbau" ("flatnose" or "slantnose") 930 under the "Sonderwunschprogramm" (special order program) from 1986 model year, an otherwise normal 930 with a 935-style slantnose instead of the normal 911 front end with the replacement of the famous "bug eye" headlamps with pop-up units.
Each Flachbau unit was handcrafted by remodeling the front fenders (option code M505 for the US and M506 elsewhere). A limited number of units were produced due to the fact that the package commanded a high premium price, an initial premium of up to 60 per cent (highly individualised cars requiring even more) over the standard price.
948 units were built in total with 160 of them being imported to the US. The Flachbau units delivered in Europe usually featured the 330 PS (243 kW; 325 hp) WLS performance kit. The flat nose greatly contributed to the aerodynamics of the car and enabled it to accelerate from 0–97 km/h in 4.85 seconds and attain a top speed of 278 km/h (173 mph) (figures with the performance kit.
Commentary about Originality from Slant Nose Owner and BAT Commentator, @wdowmaker930
This is a great looking car. I own a very highly optioned 1984 special wishes program slantnose built at Werks 1, verified by Porsche, and this looks to be legit. If you are uncertain, I would pull the car from BaT and get verification so you get the true market value of the car. True Slantnoses are very high dollar cars compared to conversions.
You can contact Porsche PPS to figure it out. Or if you have an ownership chain, you can search for where the car was originally registered and see who was federalizing these cars. You could not purchase a 911 turbo from 1980-1986 in the United States without going through the grey market and upon arrival, the car needed to be federalized. Canepa Motorsports federalized a lot of turbos in the 1980’s and Bruce Canepa is a HUGE porschefile so he keeps excellent records. You may want to reach out to a place like that to see if they have record of the car.
A few tell-tale signs that you can look for on your own to verify that this car is original: the front fenders and rear flares are steel. The black fins in the intake slots are made from wood. The original intercooler on the car was larger than a standard turbo to accommodate the increased horsepower. If you still have that, we can look at it and know if the engine was the increased horsepower engine. The sticker on the fan housing should show conditions for doing the timing of the car: it should be done at 25 degrees, not 28 or 29. The 25 degree cars are the increased horsepower (330 HP vs 300 HP) cars. The front oil cooler is also a good sign, as is your lower front bumper. The pop up headlights should also be ran by one motor, not two. So one motor powers one control arm that spreads across the front of the trunk compartment.
To address a few of the comments as well, the lack of louvers on the front slant panels is not indicative of a “fake” or aftermarket conversion. The louver delete was an option from the Sonderwunsch cars and there are several verified examples of that still in existence. The most noteworthy being a Guards Red 1986 slant owned by a gentleman in the UK. Check out his great site on the car here https://www.911flachbau.com
Oh and another thing that is indicative of the special wishes program is the boost gauge. That LED boost gauge was a custom option available for the Werks 1 cars and only a handful have them, mine also has it.
What would make this car really valuable is all the OEM equipment: seats, steering wheel, gauges, wheels, etc. But either way, you can easily verify if this car is real or not with the Porsche PPS program, which replaced their COA program. And everything I listed above. If you can check all those boxes, the car is more likely real than not. Either way, don’t undersell this thing!!
