Editorial notes
Key Takeaways
The Fairlady Z ran from 1969 all the way to today across seven generations. The S30 is the analog one everybody wants. The S130 went softer and more grand-touring. The Z31 was the first Z without an inline-six. The Z32 is the technological halo with the VG30DETT twin-turbo. The Z33 350Z brought the Z back as an affordable sports car under Renault. The Z34 370Z sharpened it. And the RZ34 is the modern one with the VR30DDTT making 400 hp. Each Fairlady Z feels like a different idea of what a Z car should be.
- S30 (240Z/260Z/280Z) values hinge on rust and originality
- Z32 Twin Turbo is the best value-per-performance classic Z
- Z33/Z34 are trackable bargains; mods can hurt resale
- RZ34 demand is strong; markups easing but still common
- JDM specs (2+2, NA, auto) usually trade at discounts
- Documentation and stock parts matter most at resale
Technical Specifications
Four engine families ran across the Fairlady Z lineup. The L-series inline-six powered the S30 and S130 from 1969 to 1983. The VG-series V6 took over for the Z31 and Z32, and the VG30DETT twin-turbo made 280 PS in JDM trim and 300 hp in the US. The VQ-series naturally aspirated V6 ran the Z33 and Z34 from 2002 to 2020. The VR30DDTT twin-turbo V6 in the RZ34 makes 400 hp.

Variants & Trims
JDM Fairlady Z trim names don't line up with what was sold in the US. The S30 had the Fairlady Z 432 with the S20 twin-cam from the Hakosuka GT-R. The Z31 had a JDM-only 200ZR with the RB20DET inline-six. The Z32 had Version R and Version S grades that never crossed the Pacific. The Z33 and Z34 had Version T, Version ST, and Type C trims that don't map to US Touring or NISMO. If you're shopping a JDM import, learn the JDM grade hierarchy first.

Should You Buy a Nissan Fairlady Z S30?
The Fairlady Z is the longest-running Japanese sports car nameplate that's still alive, and that shows in how the strengths and weaknesses have evolved across the generations. What you give up depends on which Z you're buying. The S30 trades modern usability for analog purity. The Z32 trades reliability for that 300 hp twin-turbo experience. The Z33 and Z34 trade exclusivity for daily-driver durability.

- Owners without secure parking (theft/vandalism risk)
- People who need easy parts availability same-day locally
Common Issues & Solutions
Every Fairlady Z generation has its known weak points, and almost all of them are well-documented. The S30 rusts everywhere it can find moisture. The Z32 timing belt service is non-negotiable at 60,000 miles. The Z33 and Z34 burn oil by design, and treating that as a fault is the fastest way to ruin a VQ engine. None of these are deal breakers if you know about them going in.

Differences between JDM & USDM
The Fairlady Z badge was JDM-only. Every Z exported from Japan from 1969 onward wore a numeric designation that reflected its engine displacement (240Z = 2.4L L24, 260Z = 2.6L L26, 280Z = 2.8L L28, 300ZX = 3.0L VG30, 350Z = 3.5L VQ35, 370Z = 3.7L VQ37) until the RZ34, which dropped the displacement number entirely and is simply 'Z' in export markets and 'Fairlady Z' in Japan. Mechanically the JDM and USDM cars are largely the same, but the JDM-only specifications are meaningful: the S30 Fairlady Z 432 used the S20 inline-six from the Hakosuka Skyline GT-R (twin-cam, twin-carb, 160 hp) and is one of the rarest factory Zs ever built; the S130 280ZX-T turbo was sold in the US but a JDM-only 200ZR Z31 used the RB20DET inline-six rather than the VG-series V6; JDM Z32 grades like Version R and Version S were never sold in North America; and JDM Z33/Z34 trim names (Version T, Version ST, Type C) do not map directly to US Touring/Sport/NISMO badging. The 240Z launched in the US at $3,526 in 1970 — a price Mr. K's marketing team chose specifically to undercut the Jaguar E-Type by half, and to position the Z as the credible Japanese sports-car alternative to British and Italian imports.

Pre-Purchase Inspection Checklist
Walk this checklist with the seller on the car, not from a printed sheet. The Critical items are walk-away items if there's no paperwork backing them up. On an S30 or S130 the rust check matters more than anything else. On a Z32 it's the timing belt history. On a Z33 or Z34 it's the oil consumption pattern and the clutch hydraulics. Spend 30 minutes driving it.

Original MSRP & Pricing
Original MSRP: $3,526 at launch in 1970. USD launch price of the 240Z in the United States. Contemporaries: Jaguar E-Type was approximately $5,725; Porsche 914-6 was approximately $6,099; Chevrolet Corvette base coupe was approximately $5,192. Nissan/Datsun deliberately set the price to undercut every European competitor in the segment. JDM Fairlady Z launch pricing was set in yen and varied by trim grade (Fairlady Z 432, with the S20 engine, was substantially more expensive than the L20A-powered base car).
How It Compares
The Fairlady Z's competitors changed across the generations. The S30 took on the Jaguar E-Type and the Porsche 914-6. The Z32 fought the Supra JZA80 and the RX-7 FD. The Z33 was aimed at the Porsche Boxster and the BMW Z4. The RZ34 sits against the Supra A90 and what's left of the affordable sports car market. The table below leans toward the Z's strengths because that's where the Fairlady Z actually wins.
| Feature | S30 | Porsche 911 (G-body) | Toyota 2000GT |
|---|---|---|---|
| Era/segment | S30: 1970s sports coupe | 1970s sports coupe | 1970s sports coupe |
| Collector demand | S30 high; Z32 rising | Very high; blue-chip | High; JDM icon |
| Power output | Z32 TT: ~300 hp | 276-320 hp (market) | 255-280 hp (market) |
| Engine layout | Z32 TT: 3.0 V6 TT | 3.0 I6 TT | 1.3 rotary TT |
| Weight/feel | S30: light/analog | Heavier, refined | Light, raw |
| Reliability risk | Z32 TT: heat/vac lines | Cooling/hoses; pricey parts | Turbo/aging wiring |
| Maintenance cost | Z32: medium-high labor | High parts/labor | High complexity |
| Aftermarket support | Z33/Z34: huge | Huge | Strong |
| Track capability | 370Z NISMO: strong | Balanced, fast | Light, precise |
| Modern power | RZ34: ~400 hp | 382 hp | 455 hp |
| Transmission options | RZ34: 6MT or 9AT | 8AT only (most) | 6MT or 10AT |
| Tuning headroom | VR30: strong on bolt-ons | B58: very strong | LT1: NA gains modest |
| Practicality | Z: 2-seat hatch (most) | 2-seat coupe | 2+2 coupe |
| Value stability | Z34 firming; Z32 rising | High but volatile | Strong, premium priced |
| Classic entry price | S130/Z31: accessible | Often higher | Similar |
Comparable Alternatives
If the Fairlady Z isn't the right Z car for you, the obvious alternatives are the Toyota Supra A80 for a JZ-powered grand tourer, the Mazda RX-7 FD for a lighter rotary-engined rival, and the Honda S2000 for an analog-feeling roadster. None of them have the 56-year nameplate continuity the Z does, but each one solves a different part of the same problem.

The Buyer's Read
The first question when buying a Fairlady Z is which generation you actually want. The S30 is the collector pick and prices reflect it — a clean documented 1970 to 1973 240Z under $25,000 is rare now, and concours-grade cars trade well into six figures. Skip rough S30 cars unless you are prepared for a frame-up rust repair. The entry point with less risk is a documented S130 280ZX or a Z31 300ZX, both in the $8,000 to $18,000 range for driver-grade cars.
The Z32 300ZX Twin Turbo is the 1990s pick, and it is the Fairlady Z most likely to cost you if you buy the wrong car. Get the timing belt paperwork. If there isn't any, assume the belt is overdue and budget $1,200 to $2,500 for the full kit. The twin-turbo packaging makes every repair expensive, and deferred maintenance compounds fast.
The Z33 350Z and Z34 370Z are the daily-driver Zs. Both VQ engines burn oil by design, and owners who treat that as a defect rather than a maintenance task are the ones who damage engines. Get a 6MT car, check the clutch hydraulics, and budget for the CSC fix — NISMO trims command premiums when stock.
The RZ34 is too new for long-term data, but the VR30DDTT has been in service in the Infiniti Q50 and Q60 since 2016. If you're buying one to keep, get a stock 6MT NISMO, document every service, and let the market determine where Z car values land in 20 years.
Frequently Asked Questions
- Which Fairlady Z generation is most collectible?
- S30 (240Z-era) leads for classics; Z32 TT is the 90s collector pick; top RZ34 may age well.
