Up for bidding is a 2013 PCA GT4 National Championship winning, 1995 Porsche 993. The vehicle has only been raced one season (2013), fully-refreshed, then raced twice more putting down a lap record at Watkins Glen and was only 2/1000's away from the lap record at Road America! This 993 is a very well engineered car and capable of class lap records at any track...depending on the driver of course.

The street-to-race car conversion began in October 2012 at Dawe's Motorsports  with the build being complete in January of 2013. The vehicle was raced for one season and won the 2013 PCA GT4 National Championship. It also set a PCA GT4 class lap record at every track including Sebring, Limerock, COTA, Watkins Glen, NJMP and Summit Point. 

The transmission - a Dawe short-geared custom Euro-box - is coupled to the engine via a JB ultra light-weight flywheel and a Tilton / JB triple-disc clutch. For those who appreciate and enjoy a visceral driving experience, this drivetrain coupled with the barbaric sound emanating from the Dawes custom exhaust, is nothing short of mezmorizing. 

In terms of suspension components, JRZ triple adjustable motorsport dampers are utilized in conjunction with an RSR front geometry set-up (subframe mounting points moved 3 cm). To achieve maximum weight savings and aerodynamic efficiency, this 993 has had every body panel replaced with fiberglass or S-Glass and consists of a Getty Design wide-body kit, clamshell hood, fenders, bumpers, roof, deck lid and doors. Custom cooling via naca ducts in the hood provide optimal cooling for the upgraded “big red” calipers and Gyrodisc front rotors / hat. Many steps were taken to maximize weight distribution and a favorable center polar moment of inertia, including the customized location of a fuel cell (with quick connect fill port), removal of rear seat area / replace with aluminum fire wall, and the relocation of a new Porsche factory electro-hydraulic RSR power steering pump with custom Dawe trunk mount kit. 

This car is an incident free race car, meaning the chassis is straight and the body panels are true. As with all S-glass panels, some surficial "spider cracks" have developed and the car is not without some light road rash - nothing more than what can be expected from some exciting wheel-to-wheel racing.

If you have ever driven a purpose-built 993 race car, you know that it's an extremely rewarding and engaging car to drive. This vehicle is a podium car in PCA and with some modest "detuning" via the Motec, it could be a class leader in NASA GTS4.

Engine Description: Peter Dawe has been in the racing industry for over 30 years. As a former IMSA racer, he is a renowned engine builder and chassis tuner. For my 993, Peter designed a 3.4 liter race engine (>$28,000). This displacement was chosen based on the dry weight of the vehicle (approx. 2375 pounds), so as to maximize the power/weight ratio for PCA GT4. The engine sports more goodies than can be listed, but includes Kotwica crank, Mahle cylinders, Elite heads, Pauter custom rods, 997 GT3 plenum, Roth Sport throttle bodies and M84 Motec . Based on dyno results from January 2014, the engine makes 332 RWHP and 252 ft. lbs. torque. Note this engine was refreshed in July 2013 and has approx 20 hours since this time .
