575M-Powered Ferrari 250 GTO Re-Creation 6-Speed

This Ferrari 250 GTO re-creation was constructed beginning in 1985 by its current owner at his restoration shop, Badsaddle Stables in Northamptonshire, England, using the shortened chassis of a right-hand-drive 1978 Ferrari 400i and a widened replica aluminum body sourced from Eurospares. The car was completed over the course of approximately seven years with power from a 4.4-liter 365 GT4 four-cam Colombo V12 and has since been driven regularly on the road, including a tour of Europe, alongside occasional club races and hillclimbs in the UK and abroad. In 2009, it was fitted with a 5.75-liter F133E V12 that was sourced from a Ferrari 575M and modified with Jenvey individual throttle bodies, a custom cast intake manifold, custom-fabricated exhaust manifolds, and a DTAFast sequential ECU. Additional modifications added at that time included a Ferrari 550 six-speed manual transaxle, disc brakes incorporating Wilwood calipers and rotors with adjustable bias, adjustable coilover shock absorbers, Borrani competition wire wheels accommodated by fender flares, and a foam-filled aluminum fuel tank. Finished in red, the car also features a transparent Perspex engine bulge, fixed-back bucket seats trimmed in black leather, and a Nardi wood-rimmed steering wheel. This 575M-powered 250 GTO re-creation is now offered in Bicester, England, at no reserve on dealer consignment by Sports Purpose, a BaT Local Partner, with build photos, invoices, and V5C registration.

The 250 GTO was developed in 1961 as Ferrari’s competition department sought to address the aerodynamic shortcomings of the 250 GT SWB Berlinetta for the approaching 1962 FIA International Championship for GT manufacturers. Initial design of the model began under the lead of Giotto Bizzarrini, whose 1961 firing left the remainder of styling and eventual construction to Scaglietti. Each with distinct bodywork details, 36 examples of the original 250 GTO, or Gran Turismo Omologato, were built between 1962 and 1964 to lead Ferrari to three consecutive International Championship for GT Manufacturers titles.

This re-creation’s aluminum body is said to have been widened by 2” on each side to accommodate the wider track of a 400i oval-tube frame that was shortened to match the 250 GTO model’s 2,400mm wheelbase and used as the base for construction of a 250 GTO-style spaceframe. According to the selling dealer, the body was purchased by the owner from Eurospares, which claimed at the time that it was built by Scaglietti. Previously finished in yellow, the car was repainted in red approximately six months ago. Features include faired-in headlights, rectangular fog lamps, three D-shaped nose inlets, a transparent Perspex hood bulge providing a view of the intake trumpets, triple angled fender vents, a driver-side mirror, flared rear fenders, vents behind the rear wheels, rear-window ventilation scoop, a rear spoiler, and quad exhaust outlets.

Silver-painted Borrani wire wheels with polished lips measure 15×7.5″ up front and 15×9″ at the rear and are secured by three-eared knock-offs. Avon tires measure 245/60 and 275/55 at front and rear, respectively. The suspension components and hubs are said to have been sourced from a Ferrari 365 GT4, and dampening has been updated with adjustable coilover shock absorbers. Stopping is handled by Wilwood disc brakes with adjustable bias.

The right-hand-drive cockpit houses a pair of fixed-back bucket seats trimmed in black leather with matching quilted upholstery over the center tunnel. Additional features include blue Willans harnesses, a gated shifter, and a fire suppression system.

The Nardi wood-rimmed steering wheel sits ahead of Veglia instrumentation including a central tachometer with an 8k-rpm redline flanked by gauges monitoring coolant temperature, fuel pressure, fuel level, oil pressure, and oil temperature. A 180-mph Veglia Borletti speedometer is situated to the driver’s left, but is not connected. The odometer shows 33k miles, and according to the selling dealer mileage since the build is estimated at 18k miles.

The 5.75-liter V12 is said to have been sourced from a Ferrari 575M Maranello and features dry-sump lubrication, dual overhead camshafts on each cylinder bank, four valves per cylinder, and electronic fuel injection. Modifications include Jenvey individual throttle bodies with trumpets, an intake plenum that seals again the hood panel to form a filtered cold-air box, a custom-cast intake manifold, a DTAFast sequential ECU, and custom exhaust manifolds without catalytic converters. The timing belts were replaced in 2025, while service in May 2026 included rebuilds of the throttle bodies and the replacement of the battery.

Power is sent to the rear wheels via a six-speed manual transaxle that is said to have been sourced from a Ferrari 550 Maranello.

A 2009 dynamometer sheet reflects peak output values of approximately 601 horsepower at 7k rpm and 471 at 6k rpm, although according to the selling dealer, the engine can be run to 8k rpm.

The car is pictured above while touring in the Swiss Alps.

The car is being sold on its British V5C registration document, which lists the car as a Ferrari with a first registration date of 1979.
