1973 Triumph TR6 – Fully restored road-going sports car in racing specification
Chassis number: CF 10369UO | Engine number: CF 10635UE
This exceptional 1973 Triumph TR6 is a very special vehicle. It was designed for demanding drivers and technically developed to such an extent that its performance and handling are significantly beyond the level of a standard TR6. This vehicle is not for the faint-hearted – its character and capabilities can only truly be experienced behind the wheel.
Between 2015 and 2021, the vehicle underwent a comprehensive full restoration, including complete separation of the body from the chassis and extensive technical reworking. Almost all major components were overhauled, improved or replaced. The result is a road-legal TR6 in a highly developed racing specification, combining the classic character of a Triumph with modern engine management and significantly reinforced suspension, braking, drivetrain and cooling systems.
The extensive vehicle history includes invoices totalling demonstrably more than €70,000, documenting the considerable technical and financial effort invested in this vehicle. In 2022, the TR6 was assessed by an independent expert as part of an insurance valuation and awarded a condition rating of 1.
**Engine and performance - **The original 2.5-litre engine was comprehensively developed and increased to a displacement of approximately 2.7 litres. The engine rebuild and development were carried out by SZS Motortechnik für Klassische Fahrzeuge Entwicklungs- und Vertriebsgesellschaft mbH in Harxheim, Germany. The company's managing director, Stephan Schamschula, is himself active as a Triumph driver in historic motorsport.
The output of the upgraded engine is stated at approximately 190–225 hp, depending on the stage of development and engine calibration. The development focused on both high performance and the highest possible mechanical durability.
Key engine components and equipment features:
Recommended operating fluids:
The vehicle was tested using GPS measurement and achieved acceleration from 0 to 100 km/h in approx. 5.4 seconds. This gives the TR6 exceptionally dynamic performance for a classic sports car.
**Electronic fuel injection and engine management - **A key feature of this TR6 is the modern electronic fuel injection (EFI), which overcomes the limitations of the original carburettor system. At the heart of the system is a standalone ECUMaster EMU-Black engine control unit, enabling precise control of fuel injection, ignition and other engine functions.
The ECUMaster system comprises:
**Transmission and drivetrain - **As part of the conversion, the original gearbox was replaced with an LT77 five-speed gearbox. This modification improves everyday usability and enables more relaxed driving at higher speeds without compromising the characteristic driving style of the TR6.
The drivetrain specification comprises:
The Quaife differential improves traction during sporty cornering by distributing drive torque more strongly to the wheel with the better available grip at any given moment. This is particularly advantageous when accelerating out of corners and represents a significant technical upgrade for a vehicle in this performance class.
**Suspension and chassis - **The original chassis and frame were hot-dip galvanised, achieving excellent corrosion protection. The body and the individual vehicle components were refurbished and recoated as part of the complete restoration.
The suspension specification comprises:
**Braking system - **The braking system was comprehensively reworked and adapted to the increased engine output and heightened dynamic requirements.
Front axle:
Rear axle:
**Wheels and tyres - **The vehicle is fitted with 16-inch König aluminium wheels measuring 7 × 16 inches, installed in August 2019.
Current tyre specification:
Bridgestone Turanza T005 – 205/60 R16
The track spacers are approximately:
**Cooling and fuel system - **The cooling system was comprehensively improved to meet the higher engine output and demanding operating conditions.
The equipment comprises:
**Bodywork and restoration - **The restoration was carried out as a complete body-off project. The aim was to create a technically sophisticated and long-term usable TR6 – not merely a visually refurbished original vehicle.
The scope of the restoration included:
The vehicle remains finished in its classic Royal Blue (paint code 56) with a black interior (trim code 11).
**Interior and instrumentation - **The interior preserves the classic character of the original TR6 while incorporating subtle improvements suited to the increased performance.
Equipment features:
**Technical documentation and vehicle history - **The extensive documentation contains numerous records relating to specialist components, modifications and installation dates, including technical developments from 2018 to 2021. The documents record work on the engine, gearbox, electronic fuel injection, suspension, braking system, fuel supply and vehicle electrics.
The technical equipment includes numerous components from renowned manufacturers and specialists, including Quaife, Spax, Phoenix, ECUMaster, Bosch, EBC, Hawk, Mintex, Kent, Fidanza, WOSP, RacingGreen and König.
The vehicle history contains demonstrably well over €70,000 in invoices. This underlines that substantial investment was made in the vehicle's technical development and substance, rather than merely in superficial cosmetic refurbishment.
**Summary - **With its 2.7-litre high-performance engine, approx. 190–225 hp, standalone ECUMaster injection and engine management, LT77 five-speed gearbox, Quaife differential, reinforced chassis, upgraded Spax suspension, improved braking system, Phoenix exhaust system, 16-inch König wheels and comprehensively optimised cooling and fuel systems, this TR6 offers a driving experience fundamentally different from that of a standard vehicle.
This Triumph was built for someone who genuinely wants to drive and experience it, rather than merely display it. A serious sports car for ambitious drivers: developed with motorsport in mind, road-legal and equipped with the technical specification, documentation and level of investment befitting its exceptional performance.
