An OHV engine of 1.3 L; 78.7 cu in (1,289 cc), the J13 was used in the 1965-1967 Datsun 411 sedan and wagon (originally only in the sporting "SS" series). Bore and stroke are 73 mm × 77 mm (2.87 in × 3.03 in).[1] It was also produced for the Datsun 520 and 521 trucks from 1967 to 1969 when it was replaced by the Nissan L engine. Mexican-assembled Bluebird 510s also received the J13 engine. The J13 was rated at 67 hp (50 kW; 68 PS).


The J13 was bored out to produce the J15, which was introduced in the Datsun 521 truck in 1969 and saw use in various Nissan pickup trucks like the 620 and 720 in various overseas markets through the 1970s and 1980s. It was also used in certain sedans like the 710. It was also used in the PA321 Datsun Cabstar. Bore and stroke are 78 mm × 77 mm (3.07 in × 3.03 in) for a displacement of 1.5 L (1,471 cc). The J15 produces 77 PS (57 kW; 76 hp). Max torque at 3400rpm with 12.0 kg. the fuel consumption is around 12-13km/liter in countryside, 6-7km/litter in town.


A 1.6 L (1,567 cc) iteration of the OHV J-series four cylinders was also built, mainly for utility vehicles. Bore and stroke are 78 mm × 82 mm (3.07 in × 3.23 in) for a total displacement of 1.6 L (1,567 cc). This engine was also installed by Nissan's Taiwanese partner Yue Loong in several iterations of the Nissan Violet, long after Nissan themselves had stopped using OHV engines in passenger cars.



The J18 is a 1.8 L engine that was used in various Nissan models built in Mexico. Bore and stroke are 80.5 mm × 86.0 mm (3.17 in × 3.39 in), for an overall displacement of 1,751 cc (1.75 L; 107 cu in).



The J20 is a 2.0 L (1,973 cc) inline-6 engine. Bore and stroke are 73 mm × 78.6 mm (2.87 in × 3.09 in). It produces 109 hp (81 kW) and was used in the 1966-1969 Nissan Cedric. The J20 is basically a J13 with two extra cylinders. A version of Volkswagen's two-litre, "JL" five-cylinder engine was used in the (Nissan) Volkswagen Santana with 110–140 PS (81–103 kW) and was called the "J" engine by Nissan, but it shares nothing with the original J20 even though it happens to have the same exact displacement.
