Singer may have started the Porsche 911 restomodding craze, but a slew of other companies have emerged in recent years with their own takes. One of the most prominent firms from the UK to do this is Theon Design and its latest commission, which took over 18 months to build, might just be its most impressive to date.
A Gem Of An Air-Cooled Flat-Six
No doubt the highlight of the car is the engine. It is an air-cooled, 3.8-liter naturally aspirated flat-six that sports independent throttle bodies and develops 407 hp at 7,600 rpm and 293 lb-ft (397 Nm) of torque. While the 4.0-liter engine you’ll find in a new 911 GT3 has a 100 hp advantage, Theon’s car weighs just 1,150 kg (2,535 lbs), or some 312 kg (688 lbs) less, which should make it a joy to drive.

Theon Design has added an adjustable exhaust to the car, allowing it to operate quietly in town or to scream when on the open road. Power is sent to the rear wheels through a five-speed manual transmission.
There’s plenty more to like, too. The restomod has been fitted with a TracTive semi-active suspension that’s designed to cope with the poorest roads in the UK and even has a lift kit, perfect for navigating steep driveways and speed bumps. Stopping power is provided by the brakes of a 993-gen 911 Carrera RS and sits on custom 18-inch wheels with Michelin Pilot Sport tires.

Upgrades Aplenty – But At What Cost?
Like other projects from Theon Design, the donor car was stripped back to its bare metal, and the structure was strengthened with new seam welding. It has then been fitted with lightweight carbon fiber body parts painted in Ice Green Metallic, accented by Polished Eclipse Chrome elements.
The interior is just as much a work of art as the exterior. Highlights include Recaro CS seats with carbon fiber backs, gray Alcantara, custom-made gauges, and a hidden Alpine head unit complete with six Focal speakers.
Buying a Porsche from Theon requires a healthy bank account as its commissions start at £420,000 ($564,000) for Coupe models like this, excluding the cost of the donor car. Well, you didn’t expect a 911 restomod like this to come cheap, did you?
