Road Racer: A Porsche 930 Turbo-Based 934 RSR

As I sat in the passenger seat, the smell of fuel filling the cabin from the fuel lines running above my head, I thought to myself. ‘This car doesn’t just look like a legend. It feels like one.’

Now, I am in no way capable of understanding how it actually felt to race these things, but you know what they say – imagination has no boundaries. I imagined myself strapped in tight, shooting down the Mulsanne straight, running on fear and adrenaline.

To better understand this car, let’s rewind to 1976. While the Porsche 930 Turbo was a (terrifying) sensation on the road, it was the Porsche 934, built to meet FIA Group 4 regulations, that made jaws drop.

The monstrous wide arches, a huge turbocharger mounted to its flat-six engine and minimal creature comforts, the 934 sure looked like a road car – but in reality, it was an absolute track weapon.

For purists, the Porsche 934 represents a golden age. When engineers pushed the limits of turbocharging and drivers needed bravery as much as talent.

This 930-generation Turbo is in no way a copy of that formula, but instead a chance to experience the glory days of sports car racing, in 2025.

Imported to Sweden in 1983, the base car had three owners before its transformation began. The turning point came when a rare opportunity presented itself, with the acquisition of an Andial 934 body kit.

Andial is a name that should make any Porsche enthusiast raise their eyebrows. Founded in California in 1975 by Arnold Wagner, Dieter Inzenhofer and Alwin Springer, it became Porsche Motorsport’s unofficial arm, supplying parts to teams across America.

Arnold, Dieter and Alwin’s work supported countless IMSA and Le Mans victories, and the parts are as close as you can get to factory racing equipment without an official Porsche Motorsport stamp.

This kit, purchased by a collector in Sweden, had been sitting in storage for years before finding its way into the hands of an owner brave enough to slap it on the right car.

The wild arches, aggressive stance and the golden BBS E50 wheels are all part of a formula that connects directly to Porsche’s racing icons. 

This car looks fast when standing still, but when that boost gauge begins to climb, it feels even faster; a ride of a lifetime.

The heart of this beast is a 3.3-liter turbocharged engine, built by Michael Svens of Spezialmotorer here in Sweden. After an anxiety-inducing ride, I finally understand why this car is called the Widowmaker. Five-hundred and fifty horsepower in a 50 year-old car is ridiculous, but I can see why it’s so thrilling.

Thanks to all the new transmission components, reinforced chassis and upgraded suspension, this car doesn’t just cope with the power – it invites you to use it.

It’s a straight-to-the-point invitation delivered on an old-school, hand-written letter. Despite the interior being brand new and to some extent, “luxurious” for its age, it’s all business. Even the instruments tell the story of Porsche’s racing pedigree.

A RUF tachometer, Porsche 959 speedometer and a 934/935 boost gauge tell you what’s happening behind you, and how quickly things are approaching in front of you.

At full throttle, this car feels less like a recreation and more like time travel. It’s the raw, unfiltered Porsche experience from the 1970s I’ve heard so much about for years. Honestly, it’s unforgettable.

The 934 always blurred the lines between road and race, and this tribute captures that spirit perfectly.
