Tuthill Porsche built just 15 of its Group B-inspired SCRS cars, and the first one is live on Collecting Cars with about 10 days left. The auction ends Sunday, Nov. 22, and the current bid sits at £91,611 after five bids.
The idea behind the SCRS is simple to state and hard to execute: take a 993-generation 911, the last and most refined of the air-cooled cars, and dress it as a cross between a classic 911 SC/RS and a 993 RS Clubsport. It nods to the 911 SC/RS rally cars Prodrive ran in Group B, with Tuthill preparing the Rothmans-liveried entry. Tuthill is a long-established Porsche specialist with its own rally history, so the tribute comes with real lineage.
What Tuthill did to a 1994 Carrera
According to the listing, the donor started life as a UK-market 993 Carrera first registered in August 1994. Tuthill stripped it to a bare shell, blasted it, strengthened it, and fitted steel SC/RS-style arches front and rear along with fibreglass bumpers. The listing says the work also removed excess weight while keeping refinement intact, and the rear seats are deleted in the spirit of the Clubsport.
The engine is where this gets interesting. The original 3.6-liter flat-six was rebuilt to a custom 3.8-liter specification, and the listing credits it with more than 330 horsepower, a figure that comes from the seller. The spec sheet reproduced in the listing is more specific than a horsepower claim. It lists 102mm JE pistons, forged steel connecting rods, a 993 Cup camshaft, an RSR throttle body, a 993 RS flywheel, racing valve springs, re-Nikasil barrels, and a Motec M130 ECU with data logging. Power goes to the rear wheels through a rebuilt six-speed manual with touring ratios, a 993 RS clutch plate and a KAZ limited-slip differential.
Suspension and brakes get the same treatment: MCS adjustable dampers set up for fast road use and Tuthill-made billet calipers. The wheels are 16-inch Fuchs-style alloys, 8 inches wide in front and 9 in the rear, finished in Pascha Red and Stone Grey with Cerakote-coated brightwork and wrapped in Michelin Pilot Sport 4s. The listing also notes an air box 3D-modeled from an original Prodrive SCRS, which is the kind of detail that separates a tribute from a costume.
The details that sell the story
Inside, the car is trimmed in Ocean Green and charcoal leather with basketweave seat centers, Recaro sport seats, a Tuthill carbon RS steering wheel and a bespoke Tuthill switch pack. A second set of Tuthill seats in matching trim is included. It is a restrained, period-flavored cabin, not a stripped race interior, which matches Tuthill's description of the SCRS as an analogue sports car meant to be used.
It has been used, too. The odometer shows 11,267 miles, which the listing says is the distance covered since the build was completed. Tuthill serviced it in September 2023, September 2024, July 2025 and again in September 2026, and the car is offered with detailed Tuthill build documentation and two keys. The seller has owned it for four years.
Why it stands out
Air-cooled 911 builds are crowded territory. The restomod world has plenty of 911 reinterpretations, from a Singer-reimagined 911 to the Pogea Racing PR964. What separates the SCRS is its restraint and its story. It keeps the 993 chassis and gearbox architecture, adds a purposeful but not outrageous engine, and aims the whole car at a specific piece of rally history rather than at a horsepower number. Limiting the run to 15 cars, and this being the first of them, adds to the appeal.
A few things to keep in mind before bidding. The power figure and the build narrative come from the seller and Tuthill, and bidders should review the build documentation and the 198-photo gallery. The car is right-hand drive and UK-registered, so import and registration in other markets are the buyer's responsibility. Collecting Cars charges a 6% buyer's fee on the final sale price, with a £1,000 minimum and £6,000 maximum.
