Various engine configurations were available, initially ranging from the top of the line 103 kW SOHC 6-cylinder turbo "L20ET" to the 4-cylinder Z18S and 6-cylinder LD28 diesel versions at the other end of the scale. The all-new 16-valve DOHC "FJ20" engine debuted in late 1981, and was the first four-cylinder engine from any Japanese manufacturer to employ more than two valves per cylinder (see below). Some of the top spec models featured adjustable suspension dampers that could be adjusted while driving, this was another first for mass-produced JDM vehicles. Nissan Glorias and Laurels also used the L series engines, as well as some diesel (Laurel only) variants.
