Motorsports Monday: 1979 Porsche 911

A friend of mine and I were sitting around recently, musing over what kind of 911 we’d own if we had the money. The genesis of this was his Porsche 911 ownership; he had a ’85 911 cabriolet, and while he enjoyed the car it was a bit….well, basic in terms of creature comforts and ride quality compared to his current M3. There’s some charm in that, but having driven both I’d agree that the M3 is the better day-to-day car in nearly every way. But both of us agree that, money no object, the idea behind the Singer 911s is pretty compelling; take a more modern 911 and give it the classic look, but keep most of the modern amenities plus the modern powertrain, brakes and handling. It’s become quite a popular recipe, and with classic 911 values seemingly on an endlessly rising trajectory it’s quite viable to restore or resto-mod a 911 into a dream ride and make your money back, if not then some. Today’s example is pretty interesting and unique, though – I believe it’s the first time I’ve seen someone take a 930 chassis and turn it into a “regular” 911. Backdating the late ’70s look to the early 1970s and adding in some of the iconic IROC bits, the builders took modern Fuchs replicas and a built up 3.8 naturally aspirated motor and created one pretty awesome package:

Motorsports Monday: 1986 Porsche 911 IROC RSR Replica

For some time, one of the most popular race car trends with Porsche 911s was updating them; for the most part, people would take 1970s and early 1980s 911s and dress then in 964, 993 or in rare cases even the 996. With prices the way that they are on early 911s today, that may seem sacrilegious to many! So it’s not hugely surprising that with the surge in prices of early 911s – in particular, some of the rare racing models – increasingly instead of updating many modifying the venerable track tools have instead started to backdate the cars to earlier looks. Without a doubt, one of the most popular looks in the 911 scene is the RS and RSR models from the early 1970s – a time that really defined the Porsche legend as the defacto street to track weapon. Today’s example is one such backdated car; starting with a 1986 911, the builder selected the early 70s RSR look with IROC body panels. But the transformation of this 80s icon is more than skin deep, as underneath we find a 964-sourced 3.6 flat-6 good for 250 horsepower:

Motorsport Mondays: 1974 Porsche 911 “RSR”

About two weeks ago, I wrote up two ex-Turbo 911 racers that took the builds in different directions; one, an ultimate street car with track potential and a crazy V8 LS7 swap, and the other a more traditional RSR-inspired PCA club racer. Well, today we’re back at it with another ex-930 that has been converted to more traditional RSR style, with a big IROC whale tail and some pretty trick Jongbloed wheels, along with some Skoal Bandit/Group 44 inspired decals. What do you think?

Motorsport Mondays: Dueling ex-Turbo 911s – RSR v. LS7

In the days when 930s were a tad bit more affordable than they’ve become in recent years, it wasn’t uncommon to see blown-engine examples be turned into track creations. It makes a fair amount of sense – with upgrades brakes and wider flares, the Turbo model was a natural born track car. So with that in mind, we have two very different routes that seemingly similar cars could take; both based upon Turbo models, which is your track-flavored style? First we’ll look at the 3.6 flat-6 RSR-styled PCA racer:

Motorsport Monday: 1974 Porsche 911

As 911s get increasingly faster, more complex and more expensive, there is solace in looking towards the past and more simple times in Porsche history. Those are the time, indeed, that made Porsche the legend it is; it was the lightweight, underpowered but reliable cars that created the Porsche racing legend. Sure, over the years, brutes like the 917 and 962 stole the show, but in the background there has seemingly always been the 911 racing – and winning. In the past few years we’ve witnessed these older 911s increase tremendously in value; the result of desirability and dwindling numbers, at least in part because of that racing heritage. If you wanted to build a great fast track car in the 1980s, where else would you look but the older 911 market? Unsurprisingly many were turned into track or race cars and some are still thrashed today. Such is the case with today’s 1974 911, turned into a track/race car but treated to some recent love in a unique shade of Porsche history:

Combining the great pieces off of several Porsches, you get the IROC whale-tail in the rear, the RS nose in the front, and enough color personality to make everyone green with envy. Couple that great looking paint job with the requisite Fuchs alloys, a fresh engine and a 915 5-speed and you’ve got a great looking track candidate. The seller also states the suspension has been freshened, another bonus to the potential buyer. If newer cars thrill you by performing incredible feats of speed, older cars actually teach you about driving, and the 911 is one of the best at forcing you to learn car control. Too fast going in, you’ll probably spin. While that’s not likely the outcome you’d desire, in a world of increasingly “unspinable” cars the prospect of having a car swap ends on you forces you to communicate with the car. It’s this communication that has been lost in recent generations, and you’ll not find many better cars to talk to than an older 911. This car looks absolutely fantastic and I’m sure would be a fun drive; pricing will likely end up in the mid-$20,000 range – short money for a lot of character and a great looking ride.


Motorsport Monday: 1974 Porsche 911 RSR IROC Clone Race Car

40 years ago Roger Penske created the IROC racing series as a means of throwing together a bunch of identical race cars and letting the drivers sort out who’s best. When the series began, the car Penske had chosen was the Porsche 911. 15 Porsches, identical in every way other than color, were built for the series. Based largely off the 3.0 Carrera RS, the IROC 911 used a version of the 3.0 RS engine tuned nearly to RSR-spec (316 hp) and came in with a weight just over 2100 lbs. The body was mostly that of the 3.0 RS, but with a whale tail rather than the RS’s duck tail, and the interior was basically that of the RSR. After their initial first year, Penske chose to switch to Camaros for the IROC series and the IROC 911s were sold off and most were repurposed where possible for another racing series. These cars were featured in the November issue of Excellence magazine and I would encourage anyone interested in any further details to check out the article there. That brings us to the car featured here: a reproduction of those mid-70s IROC 911 racers. This is a fully-sorted vintage racer that utilizes a 3.0 flat-six and was designed to mirror the IROC 3.0 Carrera RS. Given that very few of the original cars remain with us, this car provides a rare chance to at least have a look at a unique point in Porsche racing history.

I’d like a few more details on the engine specs and other components to get a fuller sense of this car’s racing ability prior to purchase. If the car’s mechanicals replicate those of the IROC RS as closely as the exterior does then this would be an excellent driver and offer fantastic performance. We typically see a vintage Porsche race car sell somewhere in the neighborhood of $30,000 so this car comes with a little bit of a markup. With that said, given the pedigree of the racing series if this car is a full clone of the IROC cars then the price here is probably an excellent bargain. An original IROC would certainly cost many, many dollars more so for most of us a clone such as this is our best chance at having the opportunity to drive a piece of Porsche history.
