The Z31 Fairlady Z (sold as the 300ZX in some markets) represents a pivotal point in the Z car lineage. This 1985-1989 model embraced advanced technology for its time, with features like digital dashboards and electronically controlled suspension. While still a sports car at heart, the Z31 offered a more luxurious experience than its predecessors. For Kiwi enthusiasts, owning a Z31 means enjoying a piece of 80s automotive history. However, maintaining these cars requires understanding their specific quirks and weaknesses.
Common issues include rust (especially around the rear hatch and wheel arches), faulty digital dashboards, failing electronic suspension components, turbocharger problems (on turbocharged models), oil leaks, and worn suspension and steering components. The automatic transmission can also be prone to failure.
WOF tips
WOF inspectors will pay close attention to rust, particularly around structural areas. Brake performance is critical, so check the condition of brake lines, pads, and discs. Suspension components must be in good order. Lights (headlights, indicators, brake lights) must be functioning correctly. Ensure all the lights on the dash – if they are functional – are working. Turbocharged models must meet stricter emissions standards.
About the Nissan Fairlady Z RB20DET
The Z31 Fairlady Z was available with a range of engines, including the VG30E (naturally aspirated V6) and the VG30ET (turbocharged V6). The turbocharged models offered impressive performance, but also greater complexity and potential for issues. The digital dashboard, while cool, is notorious for its unreliability. Rust can be a major problem, especially around the rear hatch, wheel arches, and floor pans. The electronically controlled suspension (if equipped) is often prone to failure and expensive to repair. Regular servicing and preventative maintenance are essential for keeping a Z31 in good running condition. Sourcing parts can be challenging, but enthusiast communities and specialist suppliers can help.
