The Nissan FJ series engine was a straight-4 DOHC 2- or 2.4 L internal combustion engine produced by Nissan in the 1980s, in 2.4 L guise as a rally motor for the 240RS, and 2.0 L for general production models. The FJ20 weighs 366 lb (166 kg); the FJ24 weighs 368 lb (167 kg). The 2.0 L variant was used in the US110 and US12 Nissan Silvia/Gazelle/Sakura, and DR30 Nissan Skyline. The 2.4 L variant was used in the Silvia based BS110 Nissan 240RS rally car. While a 1.5 L variant was designed and a prototype built, it never actually went into production. It is acclaimed by some as the forefather of the CA engine.While the DOHC CA head is similar, this is actually unlikely, as the SOHC CA was devised as a lightweight replacement for the L/Z series motors when the FJ first entered production, and the DOHC CA head appeared later when the RB series was released. The FJ has an aluminium head, chain driven cams, and an iron block. Turbo motors were only available in Japan and new Zealand and the non turbo variants were available in Japan, Hong-Kong, Australia and Europe. Datsun enthusiasts like to swap FJ engines into L or Z series powered vehicles. The FJ has similar mounting points to L/Z/KA blocks. It was discontinued in the mid 1980s due to its prohibitive cost.It featured large ports,dual valve-springs and a wide angle bucket on shim valvetrain design similar to other (later) Nissan twincams like the VG, CA, RB, and KA, series DOHC motors and the previous S20 6 cyl DOHC motor from the early 1970s GT-R. ==Specifications== These engines were developed before Nissan used the D to denote "double over head cam". The FJ is indeed a DOHC 16 valve design with mechanically actuated cam on bucket follower design. The head is aluminium and the block is iron. :The numerical value is gross mark (engine single purpose crankshaft output). :A part of numerical value is different by Skyline and Silvia/Gazelle. :There is a version of the FJ24 with 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nissan FJ engine」の詳細全文を読む スポンサード リンク
