Chassis Code Explained
| Segment | Meaning | Detail |
|---|---|---|
| S | Platform series | S — Z-car platform family |
| 30 | Generation code | 30 — first-generation Z (1969–1978) |

Editorial notes
Key Takeaways
- Nissan launched the Fairlady Z in Japan in 1969; the export Datsun 240Z (US chassis code HLS30) debuted in North America in 1970 and went on sale in Japan in 1971.
- The top JDM trim, the Z432, used the 24-valve DOHC S20 inline-six also found in the Skyline GT-R (PGC10), rated at 160 PS; Hagerty puts total production at about 420 cars.
- In its export Datsun 240Z guide, Hagerty identifies rust as a documented buying concern and recommends checking locations including the wheel arches, rocker panels, floorboards, the area under the battery tray, and the rear hatch surround.
- US-market 1973 240Zs switched to flat-top Hitachi SU-style carburetors to meet EPA rules; Hagerty reports they have a reputation for poorer reliability and tunability than the earlier round-top units.
- For US imports, confirm the individual car's manufacture date and current federal, EPA, and state requirements.

Should You Buy a Nissan Fairlady Z S30?
Why You'll Love It
- The car that put Nissan on the sports-car map Nissan's own account: the Fairlady Z ‘offered the public a fun, dashing and reliable European-type sports car at an affordable price’ and ‘was an instant hit, putting Nissan on the world's sports car map.’
- Z432's S20 twin-cam six The top JDM trim, the Z432, used the 24-valve DOHC S20 inline-six also found in the Skyline GT-R (PGC10), rated at 160 PS at 7,000 rpm, with magnesium wheels and a limited-slip differential.
- 240ZG's aero nose The JDM 240ZG's fiberglass ‘G-nose’ front end, glass-covered headlamps, and bolt-on fender flares gave it a 0.390 drag coefficient and a claimed 210-kph top speed, per Nissan.
- Panel availability reported in 2018 In its 2018 US-market 240Z/260Z/280Z guide, Hagerty reported broad availability of used or reproduced body and frame panels, including frame-rail kits and floor pans. Confirm current availability and fitment for the individual car.
Why You Might Not
- Poor body repairs on export 240Zs In its export Datsun 240Z guide, Hagerty warns about poor body repairs using fiberglass patches or excessive filler.
- US emissions carburetors have a poor reputation US-market 1973 240Zs switched to flat-top Hitachi SU-style carburetors to meet EPA rules; Hagerty reports the Datsun community nicknamed them for their reliability and tunability reputation compared with the earlier round-top carbs.
Who Should NOT Buy This
- Buyers who cannot budget for an expert pre-purchase inspection; Hagerty's US-market 240Z/260Z/280Z guide recommends one regardless of seller assurances.
- Buyers chasing full originality who haven't checked part numbers and factory stampings — Hagerty documents numerous running changes to export Datsun 240Zs.
- Buyers who accept an export Datsun 240Z seller's rust-free claim without an independent body inspection.
- Buyers planning a JDM S30 import who have not confirmed the car meets the 25-year FMVSS exemption and current import, EPA, and state requirements.
Common Issues & Solutions
| Issue | Cause | Solution | Est. Cost |
|---|---|---|---|
| Rust inspection (export 240Z) | In its export Datsun 240Z guide, Hagerty identifies rust as a documented buying concern and recommends checking locations including the wheel arches, rocker panels, floorboards, the area under the battery tray, and the rear hatch surround. | Inspect on a lift, check under the battery tray and carpet, and get a specialist estimate for any repair found. | Get a written estimate from a specialist for any rust repair. |
| Prior body repairs (export 240Z) | In its export Datsun 240Z guide, Hagerty warns about poor body repairs using fiberglass patches or excessive filler. | Have a specialist check for filler and confirm any repaired area uses proper sheet metal. | Get a written estimate before buying if repaired areas are found. |
| US emissions carburetors (1973 cars) | US-market 1973 240Zs switched to flat-top Hitachi SU-style carburetors to meet EPA rules; Hagerty reports a reputation for poorer reliability and tunability than the earlier round-top units. | Confirm which carburetors are fitted and budget for a specialist tune if flat-tops are present and running poorly. | Specialist carburetor service; get a written estimate. |
| Rubber-component inspection (export 240Z) | In its export Datsun 240Z guide, Hagerty recommends checking rubber parts in the suspension, powertrain, and body weatherstripping. | Inspect rubber components and factor replacement into the purchase. | Hagerty reported in 2021 that most rubber parts for export Datsun 240Zs were readily available; confirm current availability and fitment before purchase. |
Differences between JDM & USDM
The Fairlady Z launched in Japan in 1969. The top JDM trim, the Z432, used the 24-valve DOHC S20 inline-six shared with the Skyline GT-R (PGC10) and rated at 160 PS at 7,000 rpm, with magnesium wheels and a limited-slip differential; Hagerty puts total production at about 420 cars, nearly all sold in Japan. The export Datsun 240Z used a 2.4-liter inline-six and was designed for and debuted in North America in 1970; it went on sale in Japan in 1971 alongside two other JDM variants, the 240Z-L and the 240ZG. The 240ZG's fiberglass ‘G-nose’ front end, glass-covered headlamps, and bolt-on fender flares gave it a 0.390 drag coefficient and a claimed 210-kph top speed, per Nissan. US-market cars carry their own running-change history — for example, a switch to emissions-driven flat-top carburetors for 1973 — so verify exactly which spec, chassis code, and market an individual S30 belongs to rather than assuming it matches another market's history.

The Buyer's Read
Know which S30 you're looking at before you shop. Nissan launched the Fairlady Z in Japan in 1969, with the Z432 as the top JDM trim — its S20 twin-cam inline-six, shared with the Skyline GT-R (PGC10), made 160 PS at 7,000 rpm, and Hagerty puts total production at about 420 cars, nearly all sold in Japan. The export Datsun 240Z was a different, 2.4-liter car built for North America, debuting there in 1970 before reaching Japan in 1971.
Arrange a specialist pre-purchase inspection. In its export Datsun 240Z guide, Hagerty identifies rust as a documented buying concern and recommends checking locations including the wheel arches, rocker panels, floorboards, the area under the battery tray, and the rear hatch surround. Hagerty warns that even an export Datsun 240Z advertised as rust-free can contain rot. In its export Datsun 240Z guide, Hagerty also warns about poor body repairs using fiberglass patches or excessive filler. If you're looking at a 1973 US-market car, confirm which carburetors are fitted — the emissions-driven flat-top units have a reputation for poorer reliability and tunability than the earlier round-tops.
If you're importing a JDM S30, the cited 49 CFR provision applies once the individual car is 25 years or older — confirm current import, EPA, and state requirements for the specific car. Browse what's currently available across the S30 range.
