R30

The names were brought into line with the home Japanese and worldwide markets with the launch of the R30 series in August 1981, which was built on a C31 Laurel platform. Unlike preceding generations, four and six-cylinder versions now shared a front end of the same length. The R30 was available as a two door hardtop coupe, a four door sedan, a five door hatchback (available only in the R30 generation) or a four door station wagon. In all, there were 26 variations of the R30 Skyline available.
All versions with the exception of the wagon were usually fitted with the four round tail lights that had become a regular feature to the Skyline's design. The wagon was the ugly duckling of the range, having different tail lights, headlights and no turbo or 6-cylinder versions available - it more closely resembled a Nissan Sunny than a Skyline. The two door coupe had pillarless doors and the unusual feature of roll-down quarter windows for the rear seat passengers (a styling feature of the previous C10, C110 and C211 coupes), while four door versions all had traditional framed windows.
Notably, configurations of the R30 sold in Australia and New Zealand were missing the traditional hotplate tail lights, instead opting for more conventional styling.
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 RD28 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 4-cylinder engine by 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.
The R30 range was facelifted in August 1983 with various changes across the board; for example four wheel disc brakes were now standard issue, instead of being optional for lower-spec models. Trim specifications were revised and the 4-cylinder Z18S engine was replaced with the newer CA18E. Upgraded interior trim, new front and rear bumpers, door-mounted wing mirrors (replacing the old 'hockey stick' fender mirrors) and smoked tail lights rounded out the look.
