2003 911 Coupe X51 6-Speed

The Porsche world is full of many “tall tales” about why certain models were introduced or why cars were limited in numbers. One of my favorites is the rumor behind the X51 power kit option for the 996. It has been said that the X51 power kit was developed “just in case” the 996 GT3 didn’t get homologated for use in racing. And it makes sense, as many parts were upgraded for a measly 14 extra horsepower and 200 rpm.

The X51 engine included a modified oil pan partition box, adapted exhaust manifolds with larger cross-section for optimized flow, optimized inlet and exhaust ducts, aluminum intake system, revised cylinder heads, modified valves, larger lift camshaft, additional duel chamber oil extraction pump, a third radiator, new catalytic converter, and modified fuel maps for the DME. Whether or not the rumor is true, the X51 makes for a pretty different driving experience compared to your standard 996.

This 2003 911 Coupe 6-speed is one such X51-equipped example. It is finished in Arctic Silver Metallic over Graphite Gray Leather and has 71,000 miles on the odometer. Along with the X51 Kit, it is optioned with 18” Carrera II wheels, M030 Sports Suspension, Sport Seats, interior Aluminum bits, and more. Additionally, it features an aftermarket rear wing, center console delete kit, and Fister-style exhaust.

The exterior is in decent condition, showing normal wear for the mileage: few paint chips and scratches. While the CarFax shows no accidents, it is noted that the front bumper and right rear quarter panel have been repainted at some point. The inside also shows typical wear, mainly creasing on the sports seats and scuff marks on the lower sills. The car comes with recent service records, keys, and original parts that were removed from the center console and radio.

Over the past twelve months, cars in the 60-80,000-mile range have sold in the mid-$20s to low $30s, although none have featured the X51 Power Kit. Our Spotlight car failed to sell at a high bid of $34,996, definitely a bump for the kit and other equipment, but probably the ceiling as higher bids would have gotten into X51-equipped 40th Anniversary territory, and you know how I feel about those cars. The final bid was right on the money here.
