Datsun 240Z vs 280Z Key Differences Every Collector Should Know

If you're a fan of classic Japanese sports cars, you're likely familiar with the Datsun 240Z and its younger sibling, the 280Z. In this guide, we’ll break down the key differences between the two models, helping you decide which one is right for your restoration project, weekend driving, or collection.

A Brief Introduction to the Z Cars

The Datsun Z series debuted in 1969 with the release of the 240Z, quickly earning a reputation for performance, style, and affordability. As the series evolved, the 280Z arrived in 1975 with updates designed to improve comfort and meet stricter emissions standards. Both are part of the iconic S30 chassis line but differ in multiple areas that matter to collectors.

Engine and Performance

Datsun 240Z: Powered by a 2.4L inline-six (L24 engine), the 240Z delivers around 151 hp. It's known for its quick throttle response and light feel. Many purists prefer the 240Z for its raw, analog driving experience.

Datsun 280Z: The 280Z features a larger 2.8L inline-six (L28 engine) with fuel injection and improved torque. While the extra power helps in modern driving conditions, the heavier body and refined setup make it feel slightly more subdued.

Weight and Handling

The 240Z weighs about 2,300 lbs, while the 280Z comes in closer to 2,800 lbs. The added weight in the 280Z comes from reinforced bumpers, emissions equipment, and additional interior features. This makes the 240Z slightly more agile, while the 280Z offers a smoother, more stable ride.

Interior and Comfort

240Z: Interior design is simple and functional. Expect minimal sound insulation, fewer comfort features, and a more "raw" driving feel. This model is about performance over polish.

280Z: Adds more creature comforts, including improved sound deadening, better HVAC, and a more refined dashboard. If you're planning longer drives, the 280Z may offer a more pleasant cabin experience.

Emissions and Fuel Systems

One of the biggest changes was the move from carburetors to fuel injection in the 280Z. While this helps with reliability and fuel economy, it also adds complexity for restorers who are used to tuning carbs.

Collectors often find that original 240Zs are easier to work on with basic tools, while the 280Z’s fuel-injected system can require more diagnostics and specialized parts.

Design and Styling

At first glance, both models look similar, but there are subtle styling differences:

• Bumpers: The 280Z has larger, federally mandated 5-mph bumpers that some find less aesthetically pleasing.
  
  

• Grille and Trim: Minor design updates distinguish the front and rear fascia between models.
  
  

• Wheels: The 280Z came standard with wider wheels and a slightly more aggressive stance.
  
  

Parts Availability and Restoration Support

Both the 240Z and 280Z enjoy strong aftermarket parts support. That said, some original Datsun parts for the 240Z are becoming harder to find, which may require more aftermarket solutions or custom fabrication.

At Resurrected Classics, we offer a wide range of Datsun Z parts to support both purist restorations and modern upgrades.

Collector Value and Investment Potential

Generally speaking, the 240Z commands higher prices due to its earlier release, limited availability, and purist appeal. However, the 280Z is rising in popularity and can be a more affordable entry point into the world of vintage Datsun ownership.

Collectors seeking originality and early JDM design may lean toward the 240Z, while those looking for comfort, reliability, and a lower starting price might favor the 280Z.

Real-World Experience

Having restored multiple Z cars over the years, one thing is clear: neither choice is wrong. The 240Z excels in simplicity and analog charm, while the 280Z provides a more refined, road-trip-ready version of the same classic DNA. The best choice often comes down to your goals, daily driving, show car build, or investment.

FAQs
