In February 1983 the DR30 range received a significant boost in performance with the introduction of the turbocharged FJ20ET engine in the 2000RS-Turbo. Front brakes were also significantly upgraded to cope with the power increase. Now with 140 kW (190 PS; 188 hp) of power at 6400 rpm and 225 N·m (166 lb·ft) of torque at 4800 rpm on tap, the FJ20ET enjoyed new-found prestige as the most powerful Japanese production engine of its era.
Nissan sought to elevate the status of the DR30 Skyline as their new flagship model in light of this success, and it received a generous amount of changes to distinguish it from lesser Skyline models in August 1983. Interior equipment was significantly upgraded to now include electric windows, air conditioning and power steering as standard in the new RS-X model (for Extra) with an increased curb weight of around 1,235 kg (2,723 lb); gone were the days of the spartan, stripped-out race interior, although this could still be specified at time of purchase. But by far the most striking change to the RS was the new unique front end treatment, nicknamed Tekkamen (鉄仮面) or Iron Mask by fans for its distinctive look. The headlights were considerably slimmer, and instead of a conventional grille the bonnet now sloped down to two narrow slits above a facelifted front bumper and airdam.[10]
Further changes were made in 1984, most notably the addition of an intercooler, revised compression ratios and turbocharger exhaust housing to the FJ20ET powered model, now known as the RS-Turbo C and increasing output to 151 kW (205 PS; 202 hp) of power at 6400 rpm and 245 N·m (181 lb·ft) of torque at 4400 rpm. An automatic transmission option was also added at this time, and changes to the "PLASMA Spark" ignition system followed in early 1985 towards the end of R30 production.
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.
The C110 generation was produced from 1972 through 1977.
For export in the 1970s, the C110 and GC110 Skyline was sold as the Datsun K-series, with models such as the Datsun 160K, 180K and Datsun 240K.
The body styles were, once again, four-door sedan, two-door hardtop coupé, and five-door station wagon. The C110 was more fussy in its styling than its predecessor, particularly so in wagon form, where unusually for a wagon design, no windows were fitted between the C and D pillars. The C110 was the first version to feature the round rear lights, typical of later Skyline designs.
The Nissan Skyline GT-R hardtop arrived in September 1972 but only lasted until March 1973, when Nissan ceased its production. The oil crisis saw many people preferring economy cars and high-performance sports cars were looked down upon. Nissan pulled out of Motor Racing, so there was no purpose to the GT-R. It was not officially exported anywhere, although Nissan contemplated exporting to Australia. Only 197 KPGC110 GT-Rs were ever sold in Japan through specialist Nissan Performance shops (before it was called NISMO). This was the last GT-R for 16 years until the BNR32 in 1989.Models:
