Tuner Tuesday: 1984 Porsche 911 Turbo Convertible Slantnose Gemballa “935”

Oh, where do we start here? You shouldn’t be surprised that Sir Mix-A-Lot has a wide body, huge bespoilered Porsche 911 Turbo that’s purple; after all, he did tell you he “likes big butts”, and this Porsche’s got back. Rap stars from the 1990s really moved into a new realm of bling; West Coast saw the destruction through twist-and-bounce of countless classic 1960s cars, but rappers like Sir Mix-A-Lot moved into new territory, taking brand new “whips” and modifying them. But the self-proclaimed “Mack Daddy”‘s modern-day pimp style didn’t follow traditional trends of giant America sleds with fuzzy dice; the Sir liked European metal – including this turned up 911 Turbo Convertible Slantnose:

Revisit: 1997 Porsche 911 Andial Twin-Plug Twin-Turbo

The 1997 Porsche 911 ANDIAL Twin-Plug Twin-Turbo we featured back in September on Rennlist has cropped up on eBay. As I write this I’m not sure what the reserve is, but bidding is at $119,000$ and it’s not met yet – strong bidding for a 993 Turbo, but in line with the rarity and specialness of this car. We’ll see if it gets close to the original $170,000 asking price!

The below post originally appeared on our site September 10, 2013:

I find it extraordinarily sad that this year saw the nearly unnoticed passing of one of the great Porsche tuning firms, ANDIAL. If you’re newer to the scene, ANDIAL probably doesn’t mean much to you, but if you grew up in the 1980s or were a fan of motorsports then they were one of the top tuning firms pushing out some of the fastest Porsches in the world – they were really the U.S. equivalent of Ruf. They backed that performance up with race-winning efforts – ANDIAL became the defacto 962 race engine supplier in the United States, and racked up an impressive string of both prototype and GT racing wins and championships. Though they were very well respected, ANDIAL downsized as the trio of owners aged and then passed away, culminating in the retirement this past February of the last remaining founder, Dieter Inzenhofer, Porsche Motorsports North America bought the name, but with undisclosed plans to use it, we’ll just have to wait and see. Coming across an ANDIAL tuned car is something of a rare treat, and for the 993 they cooked up a twin-plug, twin turbo 3.8 motor that was just a monster. Today’s example is one of the best prepared in the world:

Car History
Here is the information I have been able to glean about the car.
This highly optioned car was purchased in the Chicago area by car collector John Pizer. He immediately had it flat-bedded to the Andial facility with only delivery miles on the car.
The full Andial 3.8 liter twin plug conversion was performed at an estimated cost of 55-60 thousand dollars.Andial Twin Plug
A few years later the car was purchased by collector Amir Fahti in Calabasas with around 4000 miles on the clock.
In 2007 I purchased the car from Mr. Fahti with 27,181 miles on the clock. Unfortunately Mr. Fahti had lost the build sheet on the car. Andial confirms that this is one of the 19 certified 3.8 liter twin plug conversions, of which only 17 remain. Andial Registry

Over the next few years I had Michael Schatz MKS Performancein Camarillo fettle the car into tip top condition, replacing the front differential, viscous coupler, clutch accumulator, steering rack and installing a set of GT2 uprights and tie rods, new hood shocks, breeze constant torque clamps on the intercooler hoses and forge diverter valves. I removed the k40 radar detector and installed functional front brake cooling ducts and a larger Cargraphics oil cooler. I installed yellow rear seat belts to match the front seat belts. Finally, a complete corner balance and alignment and rake was performed.

In 2011 elected to make this car into my vision of the ultimate street version of a GT2.
I contacted 1998 IMSA GT2 champion Jochen Rohr who generously supplied me with the rear wing and carbon fibre deck-lid plus the BBS wheels he had left over from that race team. I sourced a brand new OEM European narrow-body front bumper and some hand laid fender flares and commissioned Ed Palmer at Kundensport to perform the conversion.

The car is everything I could have hoped for. It looks fabulous in my eyes. It rides very smoothly. The GT2 uprights and tie rods have minimized bump steer and the ride is not harsh in any way but it still handles brilliantly. The paint is exceptional. It is the best rding 993 I have ever driven. I clay barred it using Final Detail as the lubricant over a weekend and it presents very well indeed. It is nearly impossible to put the car cover on by yourself because it keeps shooting off as the paint is so smooth. Obviously the car is brutally fast but also very tractable. The larger pistons on the RS rear calipers match the 14 inch front brakes very well. A minor service and detailing was performed last week.

With the passing of Arnold in 2011 and the purchase of Andial by Porsche Motorsports in 2012, I believe no more of these cars will be built and a stellar chapter in Porsche history has closed.

Nits to pick:

There are a few rock chips on the front.

The front tires can rub if the wheel is turned to full lock at parking lot speeds.

The Thielert dual program street/race gas ecu is a bit unsophisticated and no longer supported. They need two revolutions of the crank to start the car and can run a little rough just off of idle. It occaisionally becomes “confused” and can cough and spit for a bit. Then it remembers it’s manners and clears up. It is not foolproof. You need to make sure you have 100 octane race gas in the tank before switching to the race gas setting or damage could occur.

There is a more modern Andial aproved ecu available, but you lose the dual programming capabilities. Having the “psychopath switch” under your left hand is just too much damn fun! As a result I elected to keep the dual program ecu and live with the very minor flaws.

The price may seem outrageous, but it’s in line with some of the Ruf cars. Although this is a bit of a home-brew combination of several different car looks, I think it pulls it off exceptionally well. The GT2 flares look perfect, the wheels look perfect, I love the understated color…I have to say, the only thing I’m not really a fan of is the seatbelts. Some of the technology in the engine tuning has progressed and the owner notes that this earlier multi-level Theilert computer has its hiccups, but depending on what you wanted to do this could be solved either somewhat expensively in a standalone programmable ECU or very expensively by sending it to PMNA to let them sort it out.

I don’t think the ANDIAL name really carries the weight of the name Ruf outside of the Porsche crowd, so my guess is that someone who is really in the 993 know is going to be the one to scoop this gem up. The price is probably realistic given the rarity and the modifications, but it’s a pretty narrow market for this car. You could replicate the look easily enough if you have deep pockets, but that motor is really something special. It’s a shame that we won’t be seeing any more from ANDIAL, but I do hope then name doesn’t fade away completely into obscurity. Given the choice between this car and a Ruf, I would have to think long and hard before plunking down my hoard of cash.

Purple Haze: 1991 Porsche 911 Turbo

509

When I first saw this 965, my first thought was that I had seen it’s long lost brother before, and indeed, I had – late last year Paul wrote up a super-low mile Porsche 968 with the same color combination. The question for many (including me) was why anyone would have originally selected these shades post 1974, but as one person pointed out, if you want bland go buy a Camry. This 965 is anything BUT bland, with it’s purple on purple hue, flashy polished HRE wheels and (gulp) 739 rear wheel horsepower. Think you’d driven something faster? Unless it starts with “Boeing”, that’s not likely. Take a look then at this monster 911 Turbo:

Well, there you go. If you want a modded to the extreme 911 Turbo, it doesn’t get much better than this in the air cooled era. While most of the modifications are very desirable, I can’t help but feel that the very pricey HRE wheels look out of place on this car. Were it mine and I still wanted some polish on those wheels, I’d probably select something like the Speedline-inspired RHs linked below:

Like many of the modded cars we feature (especially of the Porsche variety), the modifications alone are worth at least the asking price in original dollars. This obviously won’t be a daily driver for anyone, but at least with some miles on the body and engine the new owner won’t be afraid to drive it, unlike that investment-grade 968 Paul wrote up. For $60,000, the price doesn’t seem as outrageous as the color combination and it appears well maintained. It also appears this is an expensive car to run, so the entry price will only be the beginning, but you’d be in rarefied air – both in power and color selection. Feeling bold?
