‘Team Speed’ Member Selling Track-ready Porsche 930 Turbo
Porsche 930 Turbo looks street-friendly–and it is–but under its skin hides loads of track-ready upgrades.
Every Porsche 930 Turbo will outperform almost any stock road car from the same era, but a serious road racer will eventually find the limit to any production road car. If you have a 911 from this era that you enjoy taking to your local road course, but you are looking for substantially better performance, you have two options. You can upgrade your car, but the downside to that approach is that your Porsche may not be as comfortable for daily driving.
The second option is to buy a Porsche 930 Turbo that is built for road racing and it just so happens that “RDuke” posted one such car in the TeamSpeed Marketplace. This 911 has proven its abilities on several popular tracks around the United States including Laguna Seca and the current owner is looking to find this sleek German sports car a new home.
930 Turbo Track Car Introduction
When the OP first posted this 1982 Porsche 930 Turbo for sale, he provided the type of information that you would expect from an experience 911 owner. As you can see, no details were omitted.
