1989 Porsche 944S2 ROW

Although the United States is one of the most important market for its sales, the 944S2 is a case where a majority of the cars sold were “Rest of World” examples. Total S2 production was 19,945 units, and of those about 6,036 came to North America. When you compare that to the 944 Turbo, 25,107 were built with 14,235 sold in the United States alone. Typically, the European versions of the 80s cars we look at had more power, but that was not the case for the S2. The M44.41 was a world engine, meaning it was only available with catalyst and rated at 207 horsepower (211 according to Porsche, although that’s the motor’s PS rating rather than HP). So what did a “ROW” 944S2 get you? Well, the shorter and lighter rear bumper treatment for one, side indicators just ahead of the rub strips, and in front you got integrated dual fog lights/driving lights rather than the fog/dummy setup on U.S. cars. In the case of this particular ’89, you also got the option for a really neat Studio cloth interior:

Feature Listing: Supercharged 2002 BMW M5 Dinan S2

I promise that this post wasn’t by design, but rather is completely a coincidence that it follows hot on the heels of the neat supercharged E34 540i 6-speed from yesterday. How do you possibly trump that potent hot rod? Well, starting with a M5 is probably a good bet.

If the E34 was a potent athlete, the E39 comes across as a consummate professional. It was immediately the new benchmark for sports sedans once again, and when BMW finally did make the call to bring a M5 to market they produced what many consider to be the definitive driver’s car in super sedan form. Whatever you had from the period, the M5 was just plain better. With 394 horsepower kicking out of is snorting S62 V8 and mated solely to a 6-speed manual transmission, it was hard to conceive how that package could possibly be improved upon.

That didn’t dissuade Steve Dinan, though. His S2 package fixed a car that wasn’t broken according to Car and Driver. Power was up to a massive 470 yet the car was still naturally aspirated. Bigger, better intake was met with bigger, better exhaust, and the whole package was kept up with bigger, better suspension and slowed down with bigger, better brakes. It was…well, bigger and better. 0-60 was dispatched in a tick over four seconds and it would do a standing quarter-mile in 12.7 seconds. These numbers won’t scare a Dodge Demon, granted, but are still really respectable today.

Of course, if “respectable” isn’t quite enough for you and you really need to surprise that Demon driver…

Tuner Tuesday Double Take: 2002 and 2003 BMW M5 Dinan S2s

There are a few select automotive tuners who can take an impressive package and refine it into an even better entity. That group includes legends such as AMG, Alpina and Ruf – all of which are staples of this segment.

Yet they are far from alone. Given the task of improving on what is generally considered to be one of the greatest sedans ever made is no small feat, but if there was one group up to it, it was Steve Dinan’s eponymous company in California.

While just about anyone can take a turbocharged engine and crank up the boost, slap a few stickers on it and call it done, the E39 M5 didn’t come with forced induction. On top of that, it was a motor which wasn’t exactly underdeveloped before it went into production. Nor were the brakes, suspension, or any other aspect of the third gen M5. But Dinan thought they could improve upon them, and with a tremendous amount of work, did.

Dinan went to town on the S62 from start to end. Out came the factory air boxes, air meters and velocity stacks, replaced by Dinan units of larger diameter and better flow qualities, along with larger throttle bodies bored out by the company. This necessitated reprogramming of the computer controls for the engine to match the new flow characteristics. To help the exhaust side of the motor, unique tubular headers were fit to a free-flowing, lightweight exhaust system. While this sounds a bit like old-school engineering, it was successful; the result was an additional 76 horsepower and 51 lb.ft of torque – basically, this was like adding a 1980 Rabbit’s worth of power to an already powerful car.

Dinan coupled the engine mods with a shorter final drive and higher rev-limiter to reach fantastic speeds. The S2 was capable of 0-60 runs around 4 seconds flat and, in unrestricted mode, geared out around 190 mph in 6th. These are still very impressive numbers today, some fifteen years after its introduction! Of course, special forged wheels from the company were added along with their signature suspension. The price was steep, at $36,000 in modifications alone – a further 50% premium on your premium sedan.

Today, you can pick up one of these super-saloons for less than what the price of the modifications cost originally making them one heck of a performance bargain, and I have two to consider for today’s Tuner Tuesday:

Right Hooker Week: 1994 Audi S2 Avant

With the news that in a short twenty-three years Britain plans on no longer having internal combustion engines for sale, I was struck with the idea of a theme week. We haven’t done one in a while, but what about looking at some of the cars that are available in England that won’t be welcome there soon, but would be right at home in my driveway? Sure, they’ll mostly be right hand drive, but I’ve done it before and for the price of some of these cars I’d be happy to offer them sanctuary when they’re no longer register-able in Great Britain.

With that in mind, I’ll start with what is likely top of my list – the Audi S2 Avant. I know, I know – most enthusiasts pine over the much more legendary, quicker and more rare RS2. But there are a few reasons for me to like the S2 even more. When I lived in England, there was a Cyclamen example that parked near my flat. I ran by it often, and even had a few daydreams as training miles passed under foot that I’d be rowing through the gears. So, it is with a bit of nostalgia that I view them every time. Next, I like the look more. The gaping guppy look of the RS2 became signature for the RS models moving forward, but the S2 is very handsome in a classic Audi way without being as shouty. But most of all, it’s the price. While RS2s are still treading in the $40-$100,000 range for decent examples, a very nice S2 Avant can be had for only a fraction of that amount:

1996 Audi S2

While some may feel that my foray into BMW ownership has swayed me to the dark side of German motoring, I still have a very large soft spot for the classic inline-5 powered Audis. And one of the most outstanding deals, until very recently, was the S2 range. Oft copied in the United States as it was never offered, the S2 was available in frequently seen Coupe and far less found sedan and Avant variations. The last is best known in its ultimate development as the Porsche-built RS2, but even the standard S2 range was nothing short of impressive. With 220 horsepower available from the 3B and later ABY turbocharged dual-cam inline-5s driven through all four wheels, they weren’t the fastest off the line but could hang with their countrymen easily on the fly. As they near legal importation status, prices have started to rise slightly – but they’re still quite affordable compared to many other contemporary limited-run performance options. This ’96 is a great example:

Double Take: 2001 and 2002 BMW M5 Dinan S2s

“Dinan’s latest work of art, he has not only fixed a car that wasn’t broken but also sought to perfect a car that everyone considers to be as close to perfection as is humanly possible: the BMW M5”, Car and Driver wrote in 2002. Dinan had, at that point, already made a reputation for themselves as the premier BMW tuner in the United States to the point where they became offered straight from the dealer. Considering that’s just occurred for Alpina here, the endorsement of the level of engineering from the California firm was resounding. Yet that is in part because Dinan’s modifications are far from just slapping a badge and some wheels on a car and calling it done. Take, for example the M5 S2.

Dinan took what many considered to be a very highly developed 4.9 liter V8 in the S62 and went old-school to up the power; and up it a lot, he did. There was no supercharger or turbocharging here; revised intake and enlarged velocity stacks were met on the other end with tubular headers and a bespoke exhaust. Each throttle body’s bore was increased, too. These changes required a reflash of the computer, but were both lighter and more powerful. As in 76 horsepower more. That’s the best part of a 20% gain on a motor that many considered to be close to peak performance! Dinan further upgraded the suspension, brakes, wheels, and final drive, along with adding a lighter flywheel. As a result, the new S2 was, well, about 20% better than the already awesome M5. But that perfection cost, and it was more than a 20% increase. A lot more.

On top of the M5’s $73,400, if you wanted a fully spec’d out S2 you’d tack on $36,000 to the price. For that amount, you could have grabbed a nice 330Ci in addition to your standard M5! But a select few did pony up the extra cash for their extra-special E39s, and today we have a rare occasion of seeing two for sale at the same time:

1992 Porsche 911 Turbo S2 – REVISIT

s-l1600

The rare 1992 Porsche 911 Turbo S2 we featured in early June remains up for sale and is still asking the same $150K price. Given its mileage and that the condition suggests it may need a little bit of work it looks like that asking price is proving to be too high, but given the general demand for rare 911 Turbos we may still see this one snapped up.

Motorsports Monday: 1988 Porsche 944 “S2”

Building a track car can be a dirty business. You can start with a branded title car or one with a ton of miles, one in poor shape or maybe just a car that needs a ton of mechanical work. The results aren’t always Roger Penske perfection, but that certainly doesn’t mean you can’t have a lot of fun. Indeed, there’s a certain freedom to having a less than perfect, not hugely valuable track-focused weapon. It allows you to head to the circuit without the emotional baggage of what would happen if midway through turn two something let loose. Take today’s 1988 Porsche 944, for example. Thorough upgraded and ready to head to the track, this S2-spec 944 may not be a lot to look at, but the entry price is less than a new set of BBS centerlock wheels for a GT3. No, I’m not joking. I just checked, and it’s $9,800 for a set of BBS FI-R wheels from Tire Rack – without tires, or shipping mind you. See, you could have a whole track car instead and still have $300 left to pay for a track day!

1991 Porsche 944S2

While cars like the Audi Quattro and BMW M3 may have popularized boxy flares with their racing credentials to back it up, in my eyes no one pulled off the muscle-bound economy look better than the Porsche 944. The addition of several inches of width and wider wheels to the 924 chassis meant an entirely new feel that mingled with supercar lines instead of Volkswagen lineage. Simply put, they were the most sensual looking German car in the 1980s, and that got even better late in the run with some subtle aero additions that enhanced and updated the look. The smooth Turbo bumpers and rear diffuser carried over to the S2 model, along with some lovely “Design 90” wheels that were also highlighting the 964 model. As Porsche moved to a full update of the watercooled transaxle cars with the introduction of the 968, the outgoing 944S2 even adopted the new “bridge” spoiler design from the not yet introduced model. Turbo looks without the associated power may have seemed strange for Porsche, but the 944S2 was no slouch in its own right. Powered by the M44.41 3-liter inline-4 that had been enlarged from the double overhead cam 944S motor, the 208 horsepower wasn’t as much as the 968 would sport but was still awfully close to what the original 944 Turbo had produced in power, and with instant torque the S2 was, and still is, a very entertaining drive. Hardly cheap, on paper they were not immediately the smart choice for a sports car buyer in 1990 and 1991, as twin-turbocharged monsters from Japan were all the rage and often less expensive than the $50,000 a 944S2 would cost you. With only around 3,600 imported to the U.S., they’re a bit rare to see but offer great Porsche build quality, performance and even practicality in a very attractive package:

1993 Audi S2

One of the most popular tuning swaps in the Audi world until quite recently was to slot a 3B/AAN turbocharged 20V motor into a B3 coupe. The “Ersatz” (replacement) S2 required a fair amount of custom engineering, but you got a sleeper package that was capable of some serious performance that the U.S. bound Coupe quattro with its normally aspirated 7A 20V inline-5 lacked. For an effectively an entire generation these custom turbocharged examples have held a special place in the market, worth more than generally every other Audi from the period, but that’s changing. Now it’s 2016 and the market has awoken to the original Quattro; really pristine examples have shot through the roof in terms of pricing. But the bigger thorn in the side for custom-made S2s is that the real factory built S2s are now importable to the U.S.. While that’s not the easiest road to travel, if you search around you can find some real budget examples of the real-deal original S2 for much less than the asking price of U.S. bound replica cars. While this 1993 is still a few years from legal importation, it certainly gets me thinking about what could be:
