    Racing Edge Paddock is pleased to offer this exceptional 1981 Porsche 930 Twin Turbo for sale.

    This highly-tuned machine is an absolute monster on the track and comes with a rich racing tapestry. Absolutely no expense was spared in constructing this extremely competitive race car and it remains a joy to drive.

    This Porsche 930 Twin Turbo carries a 993 American International Racing wide body kit complete with GT1 rear wing. Its 3.4-liter Porsche-based twin turbo engine was fully rebuilt in March 2016 and produces a roaring 715 bhp at 1.4 bar and 675 bhp at 1.2 bar. It comes with newly fitted Carrillo rods and GT3 oil pump. And with only four hours on the clock, this beast is primed and ready to race!

    This 993 Twin Turbo GT-2R racer began life as a 1981 930 Turbo (VIN WP0ZZZ93ZDS000167). The car was completely hand-fabricated by Loren Beggs of 911 Design in Montclair, California. It has been intricately constructed and consistently maintained with high-quality components across the board to deliver excellence on the track: the vehicle held the GT-1R Class Porsche Owners Cup for the 2003/2004 season and set the track record at Road America.

    Following its stellar performance, William Knight of Knightrace Porsche acquired the 993 Twin Turbo in 2005. Mr. Knight improved on the car as he saw fit over the years of his ownership, tweaking suspension and dialing in the car to his liking. During this time the car was only used for a few DE events per season.

    The current owner acquired the car in 2014 and competed in 5 PCA Club races in the GT-2R class. The car has been meticulously maintained by Innovative Autosport out of Carrolton, Texas. The car is currently housed in Chicago and is in race-ready condition.
