(a bored out 1600 cc 124-derived unit) with a custom 16-valve cylinder head fed by twin 44 mm Weber IDF carburettors. Externally the cars sported flared wheel-arches, a small "duck tail" spoiler and an F1 style air intake designed to feed the carburettors cool air from above the cars roof. All the X1/9 Prototipos were raced in the traditional Abarth lime-green/yellow and orange/pink colour scheme. The prototype nature of the X1/9 Prototipo project means that the exact number of cars produced is impossible to define. Components and entire body-shells were routinely swapped and replaced as part of the development process, but it is believed that 5 genuine cars were produced. Dallara Icsunonove In 1975 the X1/9 was chosen by Dallara to enter the World Championship for Makes in the Group 5 Special Production class. The Dallara Icsunonove (the Italian pronunciation of "X1/9") featured a modified X1/9 engine with a custom 16-valve cylinder-head and fundamental suspension and body/monocoque alterations, the most obvious of which are the massively flared wheel-arches and the oversized rear wing. Kit conversions Faran The Faran Car Co. Ltd. was a UK based company that offered their Eliminator kit in both DIY and in-house assembled form. The design featured replacement fibreglass mouldings for the front and rear wings together with front and rear integrated bumper sections. The external modifications were completed by side sill skirts and a rear boot spoiler not dissimilar in style to that found on a De Tomaso Pantera. Faran also offered conversions using Lancia or Fiat Twin Cam engine units, although some owners opted to keep the original SOHC setup. Production of the Faran kits ended following a factory fire. Eurosport Eurosport (UK) Ltd. is an X1/9 parts specialist that produced two kit variants commonly referred to as the full and bolt-on kits. The full kit was a contender to the Faran version and utilises wide replacement fibreglass moldings for the front and rear wings, together with front and rear integrated bumper sections. Side skirts completed the styling which featured Ferrari Testarossa style side air intake mouldings ahead of the rear wheels. The bolt-on kit in contrast featured replacement front and rear integrated bumper sections that were moulded to blend with the standard wings. This allowed the 1500 alloy bumpers to be substituted with ease and offer a more modern appearance. Side sill skirts were also included in the bolt-on kit. Both kits are
