The Nissan J series are straight-4 and straight-6 gasoline internal combustion engines produced by Nissan from the 1960s through the 1980s. It is similar to the BMC B-Series engine that was built in Japan under licence as the Nissan 1H before being de-stroked to become the 1.0 L Nissan C[1] [2] and 1.2 L Nissan E engines,[3] but wasn't a direct copy.[4]
A version of Volkswagen's two-litre, "JL" five-cylinder engine was used in the (Nissan) Volkswagen Santana with 110- and was called the "J" engine by Nissan, but it shares nothing with the original J20 even though it is also a two-liter engine.
An OHV engine of 1299cc, the J13 was used in the 1965-1967 Datsun 411 sedan and wagon (originally only in the sporting "SS" series). Bore and stroke are NaNmm.[5] 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 .[5]
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 NaNmm for a displacement of 1483cc. The J15 produces 770NaN0. Max torque at 3400rpm with 12.0 kg.
A 1567cc iteration of the OHV J-series four cylinders was also built, mainly for utility vehicles. Bore and stroke are NaNmm for a total displacement of 1567cc. 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.
Applications:
The J18 is a 1.8 L engine that was used in various Nissan models built in Mexico from the mid-1980s until the mid-1990s. Bore and stroke are 80.5x, for an overall displacement of and a power output of with a Nikki window carburetor.
The J20 is a 1973cc inline-six engine. Bore and stroke are NaNmm. It produces 109hp and was used in the 1966-1969 Nissan Cedric 130. The J20 is basically a J13 with two extra cylinders, although the stroke is one millimeter more.
