Nissan Z 240: Analysis of myths and reality of the legendary line

The world of car collecting is full of legends, and one of the most enduring mythological stories concerns a model called Nissan Z 240. Many enthusiasts, looking through old catalogs or hearing talk at car markets, try to find information about this particular modification, believing that it is a missing link in the history of the legendary coupe. However, the reality turns out to be more complex and interesting than the simple number in the title.

If you are looking for information about technical specifications or engine with an index of 2.4 liters under the hood of a classic sports car, you have to understand the historical chronology of the development of the Z line. Often confusion arises due to the mixing of generations, markets and unofficial tuning projects, which over time have acquired the status of “legendary versions”.

In this article we will examine in detail why the models Nissan Z 240 did not exist in the factory range, what real engines were installed on its predecessors and what the market for collectible Japanese sports cars looks like now. Understanding these nuances will help you avoid mistakes when purchasing and correctly assess the condition of the car.

Historical context and origin of the myth of 240

To understand the nature of delusion, we need to go back to the basics. Ruler Nissan Z began with the S30 model, known as 240Z, 260Z and 280Z depending on the market and year of manufacture. It's the number 240 in the title. 240Z (produced from 1969 to 1973) is often a source of confusion. People hear "240", think of today's Gen Z, and the absurd hybrid "Nissan Z 240" comes up.

In fact, the index 240 in the original model indicated the engine volume in cubic centimeters multiplied by 10 (2.4 liters). It was an inline gear engine L series, which has become the hallmark of the brand. The current generation Z, released in the 2020s, is simply called Nissan Z or Z Proto, and under the hood it has a turbocharged engine 3.0 V6, which makes the presence of a 2.4 liter version in the factory version impossible with a modern analogue.

There are many tuning shops that can install 2.4 liter engines into bodies of different Z generations for the sake of weight reduction or specific racing regulations. It's these kinds of custom projects that often come up for auction with confusing names. It is important to distinguish a factory model from a custom project.

⚠️ Attention: Do not believe advertisements about the sale of the Nissan Z 240 as a new or factory model of 2023-2026. This is either a scam, or we are talking about deep tuning of an old body that has nothing to do with mass production.

Technical characteristics of real Z series engines

Although Nissan Z 240 does not exist, 2.4 liter engines played an important role in the company's history, especially in trucks and pickups, as well as in early prototypes. However, for the Z sports cars, it was the inline six-cylinder unit that became the key. Let's take a look at the evolution of the powerplants that might be associated with the 240 number.

First generation 240Z equipped with an engine L24 volume of 2.4 liters, which produced about 150 horsepower. It was a naturally aspirated, double overhead camshaft (DOHC) unit that offered excellent responsiveness. For its time, this was a breakthrough that allowed Nissan compete with European grand tourers.

• 🚗 Model 240Z (1969-1973): Engine L24, 2.4 l, 151 hp, acceleration to 100 km/h in 7.1 seconds.
• 🚗 Model 260Z (1974-1978): Increased volume to 2.6 liters, power increased to 165 hp.
• 🚗 Model 280Z (1975-1978): 2.8 l, injection, power 145-170 hp. depending on the market.

It is important to understand that modern emissions and environmental standards would not allow the release of a modern sports car with a naturally aspirated 2.4-liter engine without turbocharging. Engineers Nissan chose the path of increasing efficiency through supercharging and reducing the number of cylinders in some segments, but in the case of GT-R and Z kept the traditions of V6 or R6.

⚠️ Attention: When looking for spare parts to restore a classic 240Z be careful with compatibility. The L24 and L26 engines have different cylinder blocks, and installing pistons from a 2.6-liter engine to a 2.4-liter requires careful processing.

Comparison table of generations and engines

For clarity, let's imagine the evolution of engines so that you can clearly see where the era of 2.4 liters ends and modernity begins. This table will help you understand the differences between the models, which are often confused with the name "Z 240".

Model	Years of manufacture	Engine size	Power (hp)	Drive type
Nissan 240Z (S30)	1969–1973	2.4L L24	151	Rear
Nissan 260Z (S30)	1974–1978	2.6L L26	165	Rear
Nissan 280ZX (S130)	1979–1983	2.8L L28E	145	Rear
Nissan 300ZX (Z32)	1989–2000	3.0L VG30DETT	300	Rear/Full
Nissan Z (RZ34)	2023–present	3.0L VR30DDTT	400	Rear

As can be seen from the table, the range of engines was constantly growing in volume and power. Going back to 2.4 liters in a modern sports car would be a step back in terms of performance, although attractive in terms of weight. However Nissan decided to maintain a balance between power and handling, leaving the volume at 3.0 liters with two turbines.

Sometimes in the tuning community you can find installation projects motor RB25 or RB26 in early Z bodies, which also creates confusion in the names. But this is already the sphere of individual creativity, and not factory specifications.

Features of maintenance and operation of classic Z

If you are planning to purchase a classic 240Z or its successors, you should be aware of the specific problems that owners face. These cars are no longer simple means of transportation, but require careful attention and regular maintenance.

One of the main problems of older models is body corrosion, especially at the suspension mounting points and in the sills. It is also worth paying attention to the condition cooling systems, since aluminum radiators of those years may have microcracks. The L24 engine is known for its reliability, but requires high-quality oil and regular timing belt replacement.

• 🔧 Checking the cylinder block: Please note that there are no cracks or signs of overheating.
• 🔧 Carburetor condition: Early models have complex carburetors that require professional tuning.
• 🔧 Electrical: The wiring may be worn out, causing the alternator and starter to malfunction.

Many parts have to be found at auctions in Japan or ordered from specialized suppliers. This does affect the cost of ownership, but for true enthusiasts this is not a deal breaker.

Modern Nissan Z and its competitors

Modern Nissan Z (RZ34) is a tribute to its predecessors, but with a full complement of modern technologies. It has no relation to the number 240, but retains the spirit of the original. Engine installed under the hood VR30DDTT — twin-turbo V6, which provides powerful traction at low revs.

Unlike older models, where control was purely mechanical and required skill, the new Z offers advanced driver assistance systems, including tire pressure monitoring, surround-view cameras and adaptive cruise control. However, despite the technology, the car retains a rear-wheel drive layout and a classic 6-speed manual transmission.

Competitors in the sports car class include Toyota GR Supra, BMW Z4 and Porsche 718 Cayman. Each of them has its advantages, but Nissan Z stands out for its unique combination of price, power and cult status.

Why didn't they return the 6-cylinder naturally aspirated engine?

Engineers explained this by the need to comply with strict environmental standards Euro 6 and higher. A naturally aspirated V6 or R6 of this size would not be able to provide the required power without excessive fuel consumption and CO2 emissions, which would make the project uneconomical.

Owners of the new Z They note the excellent ergonomics of the interior and the quality of materials, which was not always typical for Japanese cars of past years. The interior combines retro elements such as an analogue clock and circular air vents with digital displays and an infotainment system.

⚠️ Attention: When purchasing a new one Nissan Z Keep in mind that due to high demand, dealers often impose additional services or markups. Be prepared that the actual price may be higher than the manufacturer's recommended price.

Investment attractiveness and collecting

Classic models Nissan Z, especially early 240Z and 260Z in perfect condition, showing a stable increase in value. This makes them an attractive investment target. However, it is important to understand that the market requires deep knowledge and caution.

Auction houses regularly record record prices for examples with minimal mileage and original history. Restoration carried out can either increase or decrease the cost of the car depending on the quality of the work performed. The use of original spare parts is key.

For those looking for a more affordable option, models 300ZX (Z31 and Z32) are also of interest, especially the turbocharged versions. They offer excellent dynamics and more affordable prices compared to earlier models.

In the world of collecting, it is also important to consider the rarity of color and configuration. For example, 240Z in Lemon or Blue color can cost significantly more than standard versions. Exclusivity always plays into the hands of the owner during resale.
