Sold from 1983 through 1989, the Z31 300ZX name followed the numerical convention initiated with the 240Z, put forth by Yutaka Katayama, the one time president of Nissan Motors USA. The “X” designation had debuted with the previous generation Z car, the 280ZX, to signify the presence of luxury and comfort oriented features. Contrary to popular belief the Z31 model of the 300ZX (1983-1989) was actually the most popular in terms of total sales, selling over 100,000 more units than it’s Z32 successor.
The Z31 generation featured 5 different motor packages. A turbocharged dual over head cam 2.0L straight six (RB20DET, found in 200zr), a turbocharged single over head cam 2.0L V6 (VG20ET, found in 200Z/ZS/ZG), a naturally aspirated single over head cam 3.0L V6 (VG30E, found in 300zx), a turbocharged single over head cam 3.0L V6 (VG30ET, found in 300zx Turbo) and a naturally aspirated dual over head cam 3.0L V6 (VG30DE, found in 300zr).
