Project 944S: Part One - The Acquis

The Acq


'm unashamedly a massive fan of the 944 series, having owned nearly every variant offered. These cars offer incredible performance for less than a used Camry and are cheap enough that owning multiple is almost a given. It's like Pringles, you can't have just one. Our most recent acquisition started out innocently enough. We had recently sold our 1988 944 NA and wanted to find one of the rare DOHC 16V variants. Searching the Mid-Atlantic area didn't turn up any suitable candidates, owing mostly to rust problems or maintenance histories that did not inspire confidence. We knew we were going to immediately press this car into daily driver status so reliability was a key requirement. Our new car would also see about a dozen autocrosses and one or two DEs a year so a fully sorted suspension was a must. As we were ticking off blocks on our wish list, the final two were in the "too much to hope for" category; Sport Seats and a Limited Slip Differential.

of a less than complete or truthful description, it's As-Is, Where-Is, Buyer Beware.

We found a suitable candidate located just a few miles south of Salt Lake City, Utah and only about 2500 miles away from our house. Fortune would smile on us as we had a close friend only a short drive away from the seller. Messages and emails were sent, phone calls made and our friend got to spend an afternoon with the "prospect" to get an idea of what we were looking at. His assessment wasn't sparkling, but neither did it show any immediate red flags. The pluses were sport seats and sport suspension options, recent repaint in factory Guards Red, brand new tires and a motivated seller. Even better, he had elicited from the seller the amount he hoped to get for the car which is always difficult to discern when searching on the internet. My lovelier half and I mulled over the deluge of pictures and term paper length write up we received from our friend before we made our decision. Rather than try our hand at bidding on the car and let it get away, I called the We began our search in earnest on all of the usual suspects, Craiglist, Autotrader, eBay and the various forums. seller to plead our case. This is where the shenanigans of online auctions come in. The seller initially baulked at not Two major categories quickly became apparent to us, eireceiving the "eBay Protection" for selling his vehicle ther they were in terrible shape and overpriced or they were in decent shape but still overpriced. Unfortunately, through them but when I offered to send him the total agreed amount that evening through a wire transfer or Payby 1988 Porsche's entry model had started to price itself out of the market and the lack of options reflected the rise Pal he started to change his mind. He inquired about our plans for the car. I told him my wife missed our previous in base price. It was easy enough to find a car that met even 2/3 of our requirements but with a price reflecting a 944 and desperately wanted to replace it with another. He seemed impressed and told me he had already received car in much better trim. Finally, and almost by accident, two cash offers higher than ours. I was disappointed, I we stumbled on seemingly a diamond in the rough on was sure this car would get away from us! The seller told eBay. For those of you who have never purchased a car on eBay, it's somewhere in between a wholesale auto auc- me he would accept our offer because he wanted the car to go to someone who would drive it and he had a feeling the tion and Craigslist. While the highest bid wins the auction, plenty of shenanigans go on behind the scenes. And other two offers were junkyards or parts waredon't kid yourself about protection from eBay in the case houses. 12

quisition With a deal struck we were the happy owners of a 1987 944S but were left with the unanswered question of exactly how we were going to get it home. Luckily, our friend didn't mind holding on to the car while we made some decisions and got some answers. We were left with essentially two options, ship the car door-to-door or fly out and drive it back. Driving an unproven car 2500 miles is a bold choice, so it went on the back burner. After wading into the seedy world of vehicle shipping, it became quickly

apparent we would wind up spending almost half of what we paid for the car with the only guarantee that our car should arrive eventually, hopefully in the same condition it departed. With shipping now off the table, we turned to option B, fly out and drive back. A trip through the Rocky Mountains during winter was not advisable and with the holidays sapping our time and resources we resolved to wait until the thaw of Spring.


Project 944S: Part One - The Acquis

The Acq We've named all of our cars, and especially as it applies to our Porsches it's a direct reflection of the cars' character. It didn't take long before the name came to us, Red Sonja. We named her after the 80s fantasy movie where Bridgette Nielsen played a warrior princess with fiery red hair who punched above her weight. That description perfectly matched our little "S" with the diminutive looks of the base 944 but packing an additional 30 horsepower. Our friend was itching for a winter project and declared he would right the myriad of small issues so we would fall-in on a completely sorted car, ready to give us years of trouble free service. We agreed, as much for his pleasure as our piece of mind. Immediately an ever-growing list of required parts appeared and we dutifully paid the bill. Surely there was something on the Red Sonja that didn't need to be replaced? On our end, a vision started to come together. Red Sonja would feature brakes from a 944 Turbo which would necessitate larger 16" wheels. Through a stroke of luck we found some 16" 968 wheels in need of a complete refinishing. Excellent candidates for powder coating and we selected vintage gold. Red Sonja would be retrofitted with svelte European bumpers with a complimentary red and gold color scheme. Parts were ordered and our local dealership's parts manager learned to recognize my number on his caller ID. I think he enjoyed checking to see which of these odd-ball requests could still be supported by Porsche's parts system. He also gave us a tidbit of information that radically changed our planned usage of Red Sonja. Red Sonja featured all of the highly desirable options one could tick on the option sheet in 1987;

sport seats, sport suspension and a limited slip differential. The last one was so rare I had never encountered another 944S with factory LSD. Now that we had an appreciation of how rare our little car was, it was time to head out to beautiful Salt Lake City and retrieve her. Tune in for the next installment of “Project 944S� to hear about good (or bad?) preparing for a cross-country trek can be.

Tech - 1973 Carrera RSR Tribute

1973 Carrera 1973 Carrera RSR Tribute by Rob Mairs


he events leading up to my latest project, a backdated ’73 Carrera RSR, began a couple of years ago as I was searching for a used 997 GT3. This turned into a futile search as I wanted a specific color which would have been a special order car. In the process of searching I turned to the many on-line Porsche forums such as Pelican Parts, Early 911S, Rennlist and others. I stumbled across a ‘Carrera backdating’ thread on the Pelican Parts forum and became intrigued with the idea. For those of you unfamiliar with backdating, it is when one takes a later model, rust resistant 911 SC or Carrera (’78-‘88) and then replaces various body, engine, interior, suspension, etc. parts to replicate an early ‘long hood’ ‘69-‘73 911. A couple of my fantasy cars have always been the early ‘70s Carrera RS and RSRs.

Figure 1. 1973 Carrera RS

Figure 2. 1973 Brumos Carrera RSR With only 1580 of the RS’ built and 49 of the RSRs, they both have become very expensive collectibles. A ’73 RS sold last August in Monterey for $470,000, and a ’74 RSR sold at the Amelia Is. Auction in March for over $3 million; way, way out of my league. The more I read about ‘backdating’ the more intrigued I became with the idea. In searching for already built cars I found several but they all fell through for one reason or another. I then found a possible car on the Pelican Parts forum owned by a fellow named Marc Zurlinden in Monterey, CA. It turned out that this car was more than my budget but Marc and I got to talking about what it would take to build an RSR tribute. Marc in his spare time had fabricated, restored or built a number of cars including a historic 911 Trans Am car driven by Tony Adamowicz which Marc suggested I take a look at as a featured car in Excellence magazine. After a few more discussions, Marc sent me a brief proposal of how he would go about building a backdated ’73 RSR and what I should look for in a donor car. Marc’s

Rob Mairs

a RSR Tribute suggestions sounded good to me so I started looking for a donor car which I soon found a couple of hundred miles away from Marc. After reviewing pictures of the car, an ’85 Carrera wide body, and its description and talking with the owner, I called Marc and he offered to drive over and check it out. If as described, he would put it on his trailer and drive it back to his shop.

the Porsche racing community – he lives literally within earshot of Laguna Seca. After several phone conversations, pictures of cars Marc had built, email correspondence and a detailed description of what Marc would do to the car including a very detailed parts and labor breakdown, I bought the car and authorized Marc to get underway. Marc began work on the car in early March, 2012. After driving it a bit and performing a compression and leak down test of the engine he began totally disassembling the car, and I mean everything.

Figure 3. Donor 1985 Carrera

Even though I had never met Marc nor seen his work in person nor seen the donor car, and the fact that I live on the other side of the country in Maryland, I agreed to buy the car on Marc’s word and I have subsequently entrusted Marc to build my latest car. Some have asked me why (like my wife and kids). What led me to trust this guy? I may be naïve but I believe that those of us that have been enjoying and working on older Porsches all do it because we love the cars and that the people I have met on the various Porsche forums are for the most part pretty genuine folks, have many of the same interests, and Marc had a pretty long history of quality fabrication as well as established relationships with many Porsche part vendors and

Figure 4. Car totally stripped and on rotisserie

I worked with Marc and Dave Bouzaglou of TRE Motorsports in Van Nuys, CA in determining how far to go in replicating a ’73 RSR. I decide to build what I will call a ‘street’ RSR. We chose to start with a ’84-’88 Carrera primarily for the rust resistant steel body and the 3.2 engine. Since the car I bought was a CA car spending its entire life there, we found no rust issues. To turn an ’85 car into one that looks on the outside like a ’73 RSR is 9


Tech - 1973 Carrera RSR Tribute

1973 Carrera not too difficult, in theory! The basic body shell from ’69 to ’88 are the same. Only the hood, trunk lid, front and rear bumpers, flares, trim, mirrors, lights and front fenders need to be replaced or modified to look like a ’69-73 car. However it wasn’t quite that simple. There was quite a bit of fabrication necessary for both bumpers.

the engine lid for the A/C condenser, the trunk lid and the front fenders. There are several options to replicate the front fenders –buy fiberglass replacements, buy new or used early replacement fenders or cut off the light boxes on some early fenders and weld them onto the existing fenders. I chose the latter.

Figure 5. To get the bumpers to exactly match up to flares took extra fabrication

In addition there are many electrical, heat, ventilation, trim, engine and suspension items to address.

a RSR Tribute After all the fabrication work was done, the car was taken to the body shop for final body work and paint. It was put on a rotisserie, thoroughly blasted, cleaned, primed and painted top and bottom. While this was going on Marc had all the hardware, nuts and bolts plated to match the original finish and engine

We didn’t do too much to the engine. Just a Steve Wong performance chip, SSI heat exchangers, M&K muffler, MSD ignition and early 911 sheet metal. The 915 transmission was rebuilt. For the suspension we replaced the shocks with new Bilstein sport shocks, a Turbo tie-rod kit and poly-bronze bushings from Elephant Racing, new Sway-Away torsion and sway bars. The brakes were replaced with a TRE brake kit using bigger Boxster calipers.

The car came with Fuchs 7s and 9s which I had refinished by Al Reed in SoCal but I wanted a deeper look so I bought 8” and 10” Braid BZ Fuchs look-alikes in the RSR frosted finish. The interior was replaced with new period correct seats with imported Scotish wool Tarten plaid inserts made by GTS Classics in Texas.

Putting the wiring harness back, ventilation system, A/C and oil cooling hoses back in are a real chore. I am still working a few electrical issues.

In addition to these major body changes, there were mirror, lot harder than taking it apart. If you ever do this make hood latch, emblem, trim, and rubber changes to be made. sure you take a lot of pictures. Luckily Marc did! I had hoped to have the car for the summer but it was not to be. The next goal was the Chesapeake Challenge but I missed that and I finally got the car on Thanksgiving morning. Was it worth it? To me it clearly was.

The 1960 Porsche RS-60 from the Revs Institute for Automotive Research in Naples, FL was a favorite in the Cars of Sir Stirling Moss class. This RS-60 won the Targa Floria in 1960 and finished 2nd in the 1960 Nürburgring 1000. The Porsche 914/916 class included 10 examples. The Porsche Family sent the 1969 914/8, one of 2 prototypes built. It is powered by the 908 flat-8 racing engine, and surplus hand-built development prototype body. Jeff and Terri Zwart showed their 1971 Porsche 914/6 GT Werks car, built in 11/1970 for the 1971 Monte Carlo Rally. We ran into Chesapeake Region member and former PCA National president Manny Alben, as well as current PCA National President Caren Cooper and VP Tom Gorsuch. The weekend schedule was packed with not only the Concours, but also book signings, Cars and Coffee, RM Auction, road tours, automotive seminars, silent auction, and test drives. But in the end, it is a great gathering of people with a shared passion. The Amelia Island Concours d’Elegance continues to be a mecca for automotive enthusiasts. This world-class event gets better every year.

In The News - Are All 911’s To Beco Could 2016 Mark The End


post in sure does make it seem that way. According to what we read, the normally aspirated Carrera and Carrera S models, set to debut as the face lifted 991 series at Frankfurt Motor Show later this year, will both feature downsized turbo engines. specifically, the story goes on to say that the base Carrera will carry a 2.7 liter turbo flat-six while the Carrera S receives a 3.4 liter turbo allowing for nearly 30 mpg. The smaller of the two motors could produces as much as 400 hp (50 more than today's 350 hp) and the turbo 3.4 slated for the Carrera S will produce "more than 400 horsepower" without specifying how much more. Where's this information come from you ask? Did they just make it up? No, the story says that their source is none other than Dr. Erhard Mössle, the Product Line Director for the Porsche 911 Turbo, Carrera 4 and Targa who spoke to during the launch of the new 911 Targa 4 GTS in Australia and let them know the current 991 series 911 will remain in production until the end of the year. However, when we read his quotes, we can't reach the same conclusion as they did regarding turbos.

Here's what Mössle said, "This is the last one [presumably referring to this version of the normally aspirated 991], and then we start again." That's it. A Hybrid 911 Seems To Be A Given At Some

of The 911 As We Know It? Point However, the story does go on to say that Dr Mรถssle explained that the next-generation 911, set to be introduced in 2020 (the 992 maybe?), will "be engineered for hybrid power". The level of hybridization will dictate the amount of change from the 991 series platform.


In The News - Earliest Production 9

Earliest “Production� 911 In Exist


his has to be one of the single strangest stories I've ever heard in the Porsche world. Allegedly, this Porsche was purchased by the current owner (his name is Jay) in 1984, and the car was already a bodge-job of some wacky elements. It had wide RSR-esque fenders, some weird tack on rocker panel covers, a ducktail engine lid, and some IROC bumpers on a short wheelbase Porsche. Not to mention, the drivetrain had been dropped at some point, and the original 2-liter power plant was replaced by a CIS-fueled 2.7 liter engine and a 915 gearbox out of a 1974 911. It had a roll bar, and there was plenty of evidence that the car had been raced at one point.

blurry photo below). After doing a little digging, Jay seems to have found out that his Porsche is a very early build number. Chassis number 300 005, in actuality. If you look at this Porsche's internal build sheet excerpt (below) from the very earliest of 911 production, you'll see just what we're talking about. I've cropped the page to include the information about only the first 6 cars. #005 is the final car shown, and has a build date of September 21, 1964. It's been said in a number of places that "production" didn't officially begin until November of 1964, so it is possible that these would be considered "vorserie" pre-production cars. 005 and 004 were built on the same day, so it's difficult to say if 005 would be the 5th or 6th car completed. Either way, 007, 003, 001, 002, and 004 are nowhere to be found and completely unaccounted for, making 005 the earliest production (or preproduction) 911 out there. There are, of course, two 1963 911 prototypes still out there that are older; Chassis 13327 known as Barbarossa, and Chassis 13360 the protocabriolet.

Back in 1984, Jay was just a casual enthusiast who picked up a second job in order to afford a really cool Porsche to drive. In his words, "back then I beat [the car] like it owed me money". After driving it for quite a while, the Porsche was parked and he shuffled it around in storage for a couple of decades. It had sentimental value, I'm sure. Older, perhaps wiser, and with the recent surge in interest in early 911s, Jay thought it was about time to drag his out of storage and give it a thorough going over. That was We've reached out to Jay for further comment, and he has when the discoveries began. gotten back to us.

Tech - Porsche Working On Variable Porsche patents a variable-compression-rat


t looks like Porsche is not the only one that is poking at Variable Compression Ratio (VCR) engines in the hope finding better fuel economy and increased power. Nissan has developed an engine. The DOE has been spending money exploring the options for more than the past 15 years. The VCR technology couples up nicely with turbo charging- which is the trend across the Porsche product line. A better explanation of what Porsche is up to can be found at http:// ratio-engine-to-boost-power-and-fuelefficiency What is not being said in any of the articles, that I read, is that the Porsche design increases rotational mass. An increase in the rotational mass typically mandates a decease in the maximum RPM. Then again, Porsche Turbos have never been about high RPMs. The days of the 9000 RPM GT-3 may be coming to an end. Best regards, Jim

Porsche patents a variablecompression-ratio engine to boost power and fuel efficiency Porsche has received a patent on a new form of the variablecompression-ratio engine. This would be especially useful with turbocharged engines that today run at lower compression ratios, to avoid over-stressing the engine when the turbocharger is forcing more air into the combustion chambers. The patent was sought by Porsche’s huge consulting arm along with Porsche client Hilite International, suggesting the engine technology might be offered to other automakers if and when it’s made commercially viable.

Why variable compression ratio matters Today’s gasoline-engine cars compress the outside air to about a tenth its original volume, a 10:1 ratio, inside each cylinder. Compress it more and you get detonation – also called knock or ping – before the spark plug ignites the airfuel mixture at or near top dead center, when the piston is at the top of its travel. Technology has raised compression ratios to 11:1 or 12:1 and as high as 13:1 in Mazda SkyActiv cars. Premium-grade gasoline allows for higher compression ratios than regular. Knock sensors can adjust ignition timing to avoid detonation. Still, design engineers have to back off on the base compression ratio when there’s a turbocharger involved, which affects efficiency at low rpm, which reduces mpg in the vehicle and its desirability to the buyer. It also makes the car feel like a pig when your first tromp on the throttle (turbo lag). Enter the variable-compression-ratio engine and Porsche’s new technology.

How Porsche does it: adjustable length connecting rods Porsche and Hilite conceived a way to adjust the apparent length of the connecting rods, the metal arms that connect to the crankshaft and drive the pistons up and down. A solenoid allows small oil-pressure-driven rods and an eccentric

io engine to boost power and fuel efficiency adjuster to raise or lower the bearing supporting the piston. The patent diagram appears to show a high and low position currently, not a variable height. The car starts off with the piston in the high position. When the turbo begins injecting pressurized air, the piston drops to the low position. That reduces the compression ratio momentarily, allowing for more turbocharger boost and more power. The Porsche-Hilite design appears to be comparatively simple, at least compared to other variable-compression-ratio efforts that date back a century.

Development still needed From patent to engine in production could be several years. Even a relatively simple design needs to be tested for durability and quirks that might show up outside the lab. Still, engines of the last 25 years have become increasingly more complex without any falloff in basic reliability. Hilite International makes components used in variable valve timing controls (VVT) that run reliably despite their complexity. Since Porsche is a consulting group as well as an automaker, and in some years in the past made more money off consulting, this is likely to be a technology with the possibility of being adopted throughout the industry on small engines — just as Mitsubishi’s balancer shafts are now common on almost every four-cylinder engine. These designs also show that the gasoline internal combustion engine will continue to be the dominant powerplant in passenger cars.

RACE/TRACK 993 $48,000 Many on Rennlist and in PCA know my 993 to be a very well developed and prepared car that is fast and forgiving. It is that rarest of racecars in that it has taken me to the podium quite a few times and, yet, it has never been wrecked. This car spent the first four years four or five years as a street car and then became a car that I drove 99% on the track. It is technically street legal since it's tagged and titled. I've actually been stopped/been given warnings by two police officers, and neither of them cited me for the loud exhaust, roll cage, etc. Lucky, I suppose. I have a lifetime emissions waiver from the state of Maryland, so it never needs to be smogged again. Contact: Mark Samuel at 410-375-6114 35
