Tuthill Porsche 911K restomod revealed with 11,000rpm flat-six

The Banbury-based Porsche restoration house has planned a series of heavily reworked classic 911s, featuring carbon body panels and rally-spec suspension

Porsche motorsport specialist Tuthill has joined the likes of Singer, Guntherworks and Theon in creating a thoroughly revised classic 911 for the road. Called the 911K, Tuthill’s offering draws from the firm’s rally and circuit racing experience, with motorsport-derived components, an uprated engine and a retrimmed interior. 

The 911K takes inspiration from Porsche’s RS models from the 1970s, albeit with new carbon fibre body panels. The redesigned front bumper is fashioned from the lightweight material, as are the front wings and bonnet. Tuthill has also chosen carbon fibre for the roof, doors, rear bumper and engine lid, as well as the swollen rear quarter panels.

Those pumped-up arches house Fuchs-style carbon fibre wheels, and there are carbon ceramic brakes at each corner with bespoke Tuthill calipers. To dial in the car’s setup for challenging b-roads, two-way adjustable rally-spec dampers have been fitted, along with titanium torsion bars and anti-roll bars.

The engine is an uprated 3.1-litre unit that revs to 11,000rpm, although Tuthill hasn’t provided exact power figures. Given that the 911K weighs just 850kg, blistering performance is expected - especially given that Tuthill has installed a magnesium-cased six-speed gearbox, with an extra ratio than standard to make better use of the motor’s potential.

The gearbox cross-member is made from carbon fibre, as is the rear bulkhead. There’s a titanium roll cage too, which should improve the stiffness of the shell to better deal with coarse road surfaces. 

Given that Tuthill is inherently geared towards motorsport engineering rather than lavish detailing, the cabin is largely free of clutter. Tuthill has primarily focused on the driver’s main contact points, with a pair of carbon fibre seats, a new steering wheel and a bespoke pedal box. There’s also a hydraulic handbrake, which juts out of the floor next to a titanium-topped gear lever. 

Continuing with the lightweight theme, the dashboard and door panels are carbon fibre items, and buyers will be able to specify their own upholstery and trim options during the build process. Tuthill plans to build a series of 911K restomods, and the price of each could vary significantly based on mechanical specification and bespoke design requests.
