1975Nissan Z

The original Z — sold in the US as the Datsun 240Z (1970–1973, 2.4L L24 six), then 260Z (1974, 2.6L, added a 2+2) and 280Z (1975–1978, 2.8L fuel-injected). A long-hood fastback that made affordable performance a mainstream idea.

Year over year

What changed

  • The 1975 record includes only the body, engine, and transmission pairings supported by that model year's factory evidence; adjacent-year combinations and appearance packages are not inferred.

Worth knowing

Notable

  • The documented lineup exposes 4 source-backed configurations without turning standalone options into separate Z models.

Living with it

Reliability & ownership notes

  • Verify chassis code, engine, transmission, emissions equipment, and production date before ordering parts. Inspect rust and prior structural repair, cooling and fuel systems, timing-drive history where applicable, turbocharger condition on forced-induction cars, and modification quality.

Maintenance & service parts

Keep your 1975 Z on the road

Start with the service interval, then match the engine or exact version you own. Order links appear only when a catalog-backed part number is available, and every listing still needs a fitment check.
