10K Friday “80s Classic” Edition: 924 Turbo v. 5000CS Quattro Avant v. Golf Rallye v. 535i v. 300CE

One thing I really love about writing up these 10K posts is a odd combinations pricing allows me to come up with. For today’s post, I decided to do something a little different. Instead of maximizing the budget, I decided to look at it from the perspective of what was a classic 1980s car that you could buy and maintain well under $10,000. Obviously, if you’re willing to shill out much more, there are countless classics you can jump in to turn-key; but under $10,000 means with almost certainty that the car you’ll be getting in to today will be at least in part a bit of a project. Is there anything wrong with that? No, I think there’s an inherent appeal to trying to save and resuscitate a car that was in part neglected or just needs attention. Certainly I’ve tried to do that several times with 1980s cars – with mixed results. Today, I grabbed one classic from the 1980s (give or take, we’ll see…) from each of the major manufacturers – which is the one you’d like to save?

1980 Porsche 924 Turbo

Pablo from flüssig magazine has checked in with us once again, evaluating this 1980 Porsche 924 Turbo for sale in Denver that was sent to us from our reader Duncan.

Porsche’s plan in 1980 was to keep the 924 Turbo’s price under twenty grand. Now if I were to tell you that in the face of a weakening dollar against a strong Deutsch Mark that USD $20,000 has the same buying power today as USD $57,115, you’d not only have to pick your jaw up off the floor, you’d wonder why the hell Stuttgart decided it a savvy move to wipe the 5-stud hubs and rear disc brakes clean off the build sheet replacing them with four lugs and a pair of drums for Turbos destined to the US to stay under that price. Let me explain.

Porsche was still a small company 35 years ago compared to, say, their neighbors at Daimler–Benz. And when you’re a David, you do what have to in order to keep that needle millimeters away from the red lest A: you get consumed by Goliath, or B: you close up shop. Simple as that. So in order for Stuttgart to continue selling its relatively new entry level product at a far from entry level price in a market that was allotted 50% of its Fahrzeug (incoming CEO Peter Schutz would change that in 1981 to lessen dependence on the US market), costs had to be cut somewhere. Unfortunately, the rear binders were it. The way they saw it, if the 50 states version was detuned to put out 143bhp @5500 RPM and 147 lb-ft of torque at 3000 RPM further crippled by a smaller turbo, catalytic converter, and oxygen sensors, a front disc/rear drum set-up like that found on the normally aspirated 924 would be more than adequate.

The 924 Turbo made its appearance on our shores in July of 1979 as a 1980 model (easily distinguished by an exposed fuel filler cap) in a limited batch of 600 cars in an effort to keep dealers and journalists from screaming like spoiled little brats since Porsche had already started production of the 1979 model year in the summer of ’78. When you figure in that the European/ROW version got 170bhp, 180 lb-ft of torque, a larger KKK K26 turbocharger with a wastegate, and disc brakes all around, who can blame anyone for throwing a tantrum? Matter of course.

Let’s shift the subject to a more positive note and discuss more noteworthy attributes of the US spec 931. Labeled engine version M31.02, these lumps were built in Zuffenhausen and not at VW’s Salzgitter plant sporting a completely redesigned head with inlet valves that were 3mm larger (36mm) than the 924 normal allowing the engine to suck a combustible mixture of larger volume while platinum tipped spark plugs were moved closer to the inlet valves as opposed to the exhaust valves as in the 924 normal. It must noted that the normally aspirated 924 used a head of Heron design meaning that the underside of cylinder head was machined flat since the combustion chamber was recessed in the piston crown providing a “swirl effect” to the fuel/air mixture on the upstroke whereas the turbo would have the combustion chamber in the head itself. Compression ratio remained the same on all versions at 7,5:1 that increased geometrically to 10,8:1 when the turbo was spooled up to full song at 0,7 bar (9.87 lbs) beginning at around 2800 RPM. The bottom end remained the same for both the blown and unblown version, save for the new Mahle pistons, as it was robust enough to cope with the power increase.

The clutch size increased from 215mm to 225mm control hydraulically this time, cable operation was left to the normally aspirated group. Power went through a larger 25mm diameter driveshaft spinning on three bearings mating to a Porsche designed G31.02 gearbox with a revised final drive ratio of 4,71:1 used in the normally aspirated European 924 while the 0,706 5th gear was swapped out for 0,60:1, this in the name of better compatibility for our roads. While all of this may not matter one whit to one of little technical aptitude, the driver will most certainly find the Turbo’s appeal a fortiori when engaging the dog-leg first borne of racing pedigree.

Now that I’ve lain before your feet a small primer on what the 924 Turbo was about, I’d like focus your attention to this superb little brick draped in L90E Alpinweiß. The toolkit, that’s when I knew this 931 would be worth a bother…perhaps a flight in from somewhere farther. Universal pliers, rim wrench, spark plug wrench, operating rod for rim wrench, operating lever for spark plug wrench, handle and Philips/Flat head insert, and a double-ended 10mm/13mm spanner in the original tool roll pouch speaks volumes of what to expect in terms of completeness and originality with this example.

Rare Wasser Porsches: 1982 924 Turbo and 1988 924SE

If for some time the Porsche 944 is one of the most under appreciated cars in the 1980s German car world, the 924 is even the more red-headed stepchild. But get past the stigma of the 924 as the “poor man’s Porsche”, and the details are quite good. They’re nice looking, aerodynamic coupes that are rear drive for enthusiasts. Like the rest of the Porsche lineup from the late 1970s and 1980s, they had great build quality overall and were solid products. Many of the “big brother” 944 items work on the 924, too – especially true in the later 924S models, so they can be updated and modified just like the 944s. They enjoyed a rich racing history in both naturally aspirated and turbocharged variants, with the first “Carrera GT” being a 924 model. Plus, the 924 was the development model which resulted in the much more prized 944 and 944 Turbo. And within the lineup, there are really some great hidden gems of classic cars that can be had on a budget. Today I have two nice examples of some of the rarer models of the 924; a late run 924 Turbo and a last of the breed 924S Special Edition:

1980 Porsche 924 Turbo

Two events transpired yesterday that, for me, relate to this car. First, I was watching some of the Mecum auction action, and a low mile Porsche 993 Turbo in Arena Red came across the block. I watch in semi-horror as this modern Porsche crested $170,000 quickly. Now, I’m sure to someone that car is worth $170,000 – and speculation will probably continue to drive prices on the last of the air-cooled cars higher – but to me, that market is just absolutely insane and in need of a serious correction. The second event was that I took my very much not-perfect, not low mile and fairly compromised Audi for a drive down the road. The suspension is set to punish, the heat is stuck on, there’s no radio, and it smells vaguely of mold; I smiled all the way. Do you need a perfect car to just enjoy a drive? No, I don’t think you do. Would I have felt better if my car was an absolute pristine 100 point Sport Quattro? No, I think I’d be afraid to drive it, honestly. That’s what makes second-tier cars so appealing. The values aren’t high enough that you’re afraid to purchase or drive them, but they’re still special enough to give you a smile when you take them out. Driving down the road, not many people know what my Audi GT is anymore, and I’m okay with that. I imagine the same feeling occurs for Porsche 924 Turbo owners:

1980 Porsche 924 Turbo

It probably sounds crazy, but I find the 924 Turbo pretty fascinating. Born at a time when smaller displacement turbocharged engines were the wave of the future and the rage in motorsport, the 924 is still one of the most aerodynamic cars to make it to the public. This resulted in good fuel economy, which combined with hatchback practicality meant it was a reasonable daily driver. But the weight distribution and turbocharged power plant meant it was at home on the track, too – in turned up Carrera GT, GTS and GTR versions it was a hugely successful race car. It was good looking, too – subtle curves, great ATS wheels and just enough vents and ducts to hint at performance potential. Really, it’s a great package – but in spite of this 924s in general remain one of the cheapest Porsches available. That means you can get into one for quite a deal these days while the rest of the market continues to pull out of reach:

1980 Porsche 924 Turbo with 37,000 miles

Last week, I wrote up a clean and original 1982 924 Coupe, a reminder of the relatively unloved father of the much more appreciated 944 and 968. Despite there being many of these good handling, fun to drive and affordable Porsches available in very good condition, most people still stay away from them because they’re “not true Porsches”. Perhaps even more unloved than the 924 is the more potent version of the aerodynamic coupe, the 924 Turbo. This is probably due to the generally unloved nature of the 924, which resulted in low residual value for what was at the time a complicated and expensive car. Today, finding a good condition 924 Turbo is more difficult than finding regular original 924 coupes, but there’s a nice one on Ebay today:
