Motorsports Monday: Tube-frame Porsche 911 RSR LS3

Ah, another Motorsports Monday, and another opportunity to tick off the purists! I’ve had a string of LS swapped cars that I’ve reviewed recently, and here’s another to add to the list. In the 1990s, Porsche actually ran a program to develop a tube-frame race car; manufactured by Fabspeed – who notably also built Porsche’s tube-frame 944 racers, one example is still actively campaigned by Musante Motorsports in Connecticut. This car doesn’t appear to have the credentials of that particular example, but switching to a tube frame really allows racers to optimally set up both the suspension and engine configurations. In Fabspeed’s case, they moved the engine forward to create a mid-engined 911 long before the GT1 project. In this example’s case, it’s allowed for a 6.2 liter, 525 horsepower V8 to be mounted in the back. Under the guise of early 1970s RSR bodywork, this is clearly a track weapon:

The real gem here is the LS3 Engine; click on the link to know more but basically it’s an all-aluminum screamer belting out 525 horsepower and 471 lb.ft of torque with 10.7:1 compression. It’s a full on race motor, but unlike Porsche motors it can be had on a budget – an undressed example will set you back only around $9,000 and you can get parts at any GM dealer. That’s the huge advantage to running the LS motors versus the original Porsche mills. Other pieces seem well chosen and tidy – there’s something that’s indescribably cool about the look of the 1970s cars, even if this one isn’t original. With some period decals and an upgraded set of wheels, this car could really stand out – as if the speed it’s capable wasn’t enough. It would be interesting to know what the reserve is set at; currently it’s unmet with bidding at not much more than the engine cost alone. If it doesn’t go much higher, you’ll be getting a budget Porsche that’s capable of speed normally associated with cars that cost 10 times as much.

    I’ll go one better on you Carter, I got your Porsche race car chassis right here (also easily convertible to an a M coupe race car):

    All that’s required is some fiberglass construction background, or a strong desire to learn. 😉

    My race tech inspector built a similar car. It was a brilliant execution, beautiful and blindingly fast, but he was never able to solve the cockpit heat issues to the point where he wanted to drive it much. Bring A CoolShirt!

    The picture from the back with the bodywork removed makes it look like the scariest VW Beatle in the universe. Lol
