The Datsun Sports 1500 (SP310) was a small roadster built in Japan in the 1960s.

History

Datsun's first real sports cars were the SP310 Fairlady 1500 (right-hand drive) and as the SPL310 for left-hand drive.Exhibited as "Datsun Fairlady 1500" at the Tokyo Motor Show in October 1961. The chassis is a diversion of the Datsun Bluebird 310 series, with front wheel independent suspension, wishbones, coil springs, anti-roll bar, telescopic dampers, and an box-type ladder frame X-shaped reinforcement member added between the front and rear suspension support parts to further increase rigidity with distribution of weight at 54.6% front axle and 45.4% at rear axle,at the rear rigid axle, semi-elliptic leafsprings, telescopic dampers. This member is also a major feature of the S310 type family, which includes Silvia.

The car was well equipped with a transistor radio, and hardtop. The first SP310 also had a special third seat built in laterally left-facing behind the front seats. Although many British fans brands thought that the Datsun Fairlady was a copy of the MGB. Considering the time, it takes to convert a production line to a new model, it is equally inconceivable that the Datsun had copied the MG, and vice versa. However, the two cars have some then common styling details, which led to this erroneous assumption.

They had a Nissan G15 engine with with cast iron block and head a single SU carburettor and a displacement of 1497 cc and compression ratio of 9. There was again a manual four-speed gearbox with synchromesh gears on 2nd, 3rd and 4th. By October 1962 In addition to the export DATSUN 1500 (SPL310), the Japanese domestic model Fairlady 1500 (SP310) is announced. Equipped with an in-line 4-cylinder G-type engine (71 horsepower / 5,000 rpm). Later by June 1963 in response to the success of the Japanese GP, Nihon Kikaki SU X2 downdraught carburettors were installed and the output was improved to 85 horsepower / 5,600 rpm.
