J20
The J20 is a 2.0 L (1,994 cc) engine. It produces 109 hp (81 kW) and was used in the 1965-73 Nissan Cedric. 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.
