to choose five candidates as the first class of Nissan Miss Fairladys, modeled after "Datsun Demonstrators" from the 1930s who introduced cars. The Fairlady name was used as a link to the popular Broadway play of the era My Fair Lady. Miss Fairladys became the marketers of Datsun Fair Lady 1500. SP311/SPL311 Many changes were made in 1965. Though the 1.5 L SP310 continued in production through January, a new 1.6 L R16-powered SP311 and SPL311 (left-hand drive) replaced it. The new model was first shown at the 1964 Tokyo Motor Show, but did not enter production until March 1965. The restyling was executed in part by Count Albrecht Goertz, who would later be involved with designing the first Fairlady Z. Marketed as the Fairlady 1600, or the Datsun Sports 1600 in many export markets including North America, it featured 14 inch wheels and minor exterior changes. The SPL311 was also known as the "Roadster" on the West Coast of the United States. The front suspension was independent, using coil springs over hydraulic shocks. Rear suspension was a common leaf springs design, damped with hydraulic shocks. The 1600 SPL311 came with a pair of SU carburettors. The engine produced . The R16 is an in-line four cylinder OHV engine. Early SPL311 came with a high compression engine that had three main bearings, hydraulic lifters, a cast iron block and cast iron head. Timing of the distributor could be easily adjusted to reduce pre-ignition knock and thereby tune for questionable quality gasoline. Engines in later SPL311 had 5 main bearings and this addressed a design weakness. Top speed for the SPL311 with approximately 91 octane gasoline was approximately 105 mph. The axle gearing suffered from design limitations and Datsun performance parts offered a cooling system as a retrofit. Steering used a worm gear design. The hood badge said "Datsun" in individual letters, the rear badge said "Datsun 1600", and the side badges said "Fairlady" (Japanese market) or "Datsun 1600" (export market). The SP311 continued in production alongside the later 2000 model through April 1970. The first Nissan Silvia coupe shared the SP311's platform. The CSP311 Silvia had an R16 engine developing 96 hp and used a modified Fairlady chassis. The Silvia was the first car fitted with Nissan's new R engine. The R engine was a further development of the 1,488 cc G engine. Early in 1968 the 1600, just as
