Gunther Werks refines the 993 911 with stunning 400R
Updated: Jul 5, 2018
Classic cars like the Porsche 911 have been rising in value recently, but that hasn’t deterred enthusiastic tuners from stripping them out, cranking up the power and subtly refining the styling for well-heeled connoisseurs. The latest is Gunther Werks with the stunning 400R, which is designed as the ultimate 993 911 and will be built in incredibly limited numbers.
Gunther Werks starts with a 993 911 body shell, but the finished product is an altogether lighter, more exciting beast. The reworked body panels are made of carbon fiber, as is the deck lid, roof and widened rear wing. The company says bodywork is vacuum bagged and baked in a pressurized autoclave at more than 250° C (482° F) to make it more rigid. You don’t need to be a trainspotter to realize the 400R is wider than the regular 993, but the 30 mm (1.2 in) arch extensions don’t ruin the fundamental rightness of the classic Porsche shape.
Under the new, wider body, the car sits on adjustable KW Clubsport coilover suspension, with a hydraulic lift system to make sure you don’t scrape that lovely nose on speed bumps or steep driveways. A nose lift wasn’t available on the 993 when it launched in 1993, but this is one case where modernity is preferable to originality. Gunther Werks has carried the original aluminum wishbones over for the new car’s suspension, but the bushings, links and sway-bars have all been reworked for service in the 400R.
The 993 was the final air-cooled Porsche 911, so it should come as no surprise that the 400R is powered by an air-cooled engine – albeit one with a bit more get-up-and-go than standard. It displaces four-liters, and has been overhauled with new pistons, a new engine management system, coil-over plug fuel injection and individual throttle bodies among a list of changes too numerous to list here. The resulting unit makes more than 400 hp (298 kW) of power and 447 Nm (330 lb-ft) of torque, with a redline of 7,800 RPM.
