The Japanese automotive market has always been famous for its unique engineering solutions, but few projects have caused such a resonance around the world as legendary Z series. These are not just sports cars, they are a symbol of an era when the balance between affordability and performance was achieved almost perfectly. For many enthusiasts Nissan Z became the starting point in understanding what a rear-wheel drive car should be like for driving.
The history of these cars is inextricably linked with the name of Yasuji Kazawa, an engineer who dreamed of creating a “Japanese Mustang”, but with a more refined character. The result was the 240Z, which appeared in the late 1960s and instantly captured the hearts of racers and collectors. Today, more than half a century later, Z series continues to evolve, maintaining the spirit of the original, but introducing advanced technologies.
In this article we will analyze in detail all generations, from classic linear six-cylinder units to modern VR30DDTT. You will learn what to look for when buying, how to distinguish an original from a copy, and why these cars are so valuable on the secondary market.
Birth of a Legend: The Era of the Fairlady Z and 240Z
It all started in 1969, when the company Nissan introduced the Datsun 240Z model to the world. It was a real breakthrough: a lightweight chassis, a spacious interior and a powerful inline six-cylinder engine that provided incredible dynamics for its time. The “long hood, short tail” design became iconic and was copied by competitors for decades.
Model 240Z was equipped with a 2.4-liter L24 engine that produced about 150 horsepower. By the standards of the time, this was more than enough to beat most European competitors that cost twice as much. The car was offered in both coupe and soft-roof versions, which made it universal for different climate zones.
In Japan the car was sold under the name Fairlady Z, after the popular American opera My Fair Lady. This name emphasized the elegance and sophistication of the model, in contrast to the rougher image that was often associated with American muscle cars. It was this model that laid the foundation for the entire subsequent line of Nissan sports cars.
- 🏁 Lightweight aluminum hood and roof for reduced center mass.
- 🛠️ Independent suspension on all wheels for excellent handling.
- 🚗 Ergonomic interior with the ability to transport passengers in the back seat.
The Rise of the 80s and 90s: Z31, Z32 and the Turbo Era
Evolution did not stand still, and in 1983 the classic design was replaced by a more angular and futuristic 300ZX (Z31 body). This generation was marked by the introduction of turbocharging, which was a real revolutionary step. Engine VG30ET made it possible to achieve power levels previously unavailable for serial Japanese cars.
In 1989 the world saw 300ZX (Z32), which is often called the pinnacle of evolution of the Z series. It has an all-aluminum engine VG30DETT with twin turbocharging and 4WS active steering system. Handling has become standard, and the interior has turned into a space cockpit with digital instrument panels.
However, the Z32 was the last generation that could be purchased in the United States with a manual transmission as standard without a turbo. This made a version with an engine VG30DE (atmospheric) extremely popular among fans of drifting and tuning.
What's special about the VG30DETT engine?
The VG30DETT engine was designed with separate ignition systems for each cylinder, which avoided detonation at high boost pressure. Its cylinder block is made of aluminum, which significantly reduces weight compared to steel counterparts.
- ⚙️ Double turbocharging for instant response to the gas pedal.
- 📊 Digital dashboard with customizable display options.
- 🛞 Optional rear wheel steering system.
⚠️ Attention: When purchasing a used Z32, be sure to check the condition of the intercooler and turbos, as problems with oil lines often occur due to age.
Back to basics: 350Z and 370Z
After a break caused by the financial difficulties of the group in the late 90s, the Z series was revived in 2002 with the model 350Z (Z33 body). The designers deliberately abandoned the angular shapes of the '90s in favor of flowing lines reminiscent of the classic 240Z. This Generation regained the trust of fans and became a bestseller.
With my heart 350Z became a new engine VQ35DE 3.5 liter, which was famous for its linearity and reliability. Subsequently, its volume was increased to 3.7 liters in the model 370Z, adding VVEL variable valve timing technology. This made it possible to obtain more than 330 horsepower while keeping weight within reasonable limits.
During this period, the Z series also gained the iconic Nismo variant. Versions 350Z Nismo and 370Z Nismo offered improved aerodynamics, sports suspension and stronger brakes. These cars became true track day machines accessible to the average buyer.
- 240Z (1969-1978)
- 300ZX Z32 (1989-2000)
- 350Z/370Z (2002-2020)
- New Z (2022+)

Technical characteristics and engines
The secret to the success of the Z series lies in the use of engines from the L family, followed by VQ and VR. In-line six-cylinder engines ensured smooth running, and V-shaped sixes added compactness and power. Modern VR30DDTT combines twin turbocharging and direct injection technologies.
Below is a table of the main characteristics of engines that were installed on different generations of the model:
| Model | Engine | Volume (l) | Power (hp) | Torque (Nm) |
|---|---|---|---|---|
| 240Z | L24 | 2.4 | 151 | 201 |
| 300ZX (Twin Turbo) | VG30DETT | 3.0 | 300 | 400 |
| 350Z | VQ35DE | 3.5 | 287 | 363 |
| 370Z Nismo | VQ37VHR | 3.7 | 350 | 387 |
| New Z | VR30DDTT | 3.0 | 400 | 475 |
It is important to note that all of these units have high potential for tuning. Cylinder blocks are strong enough to withstand significant increases in boost pressure when properly tuned.
☑️ Checklist for checking the engine upon purchase
⚠️ Attention: VQ and VR series engines are sensitive to oil quality. Regular oil changes every 5,000 km are mandatory to prevent wear on the hydraulic compensators.
Modern Nissan Z and its features
In 2022 the world saw a new generation Nissan Z (RZ34), which brought back classic design elements such as round headlights and a roof bubble. However, under the hood hides a modern VR30DDTT with twin turbocharging, developing 400 horsepower. This is the most powerful production Z in history.
The new product received a 9-speed automatic transmission, although a 6-speed manual was retained for enthusiasts. The dynamics of acceleration to 100 km/h is about 4.5 seconds, which puts it on par with the best European competitors. The interior is designed in a “time capsule” style with modern screens.
System Launch Control and driving modes Sport and Track allow you to adapt the behavior of the car to different conditions. However, it is worth remembering that a modern car requires more complex maintenance compared to the classic models of the 70s.
- 🚀 Accelerate to 100 km/h in less than 4.5 seconds.
- 💻 Multimedia system Apple CarPlay and Android Auto.
- 🎛️ Traction and stabilization control modes for the track.
When shopping for a new Z, look for the Nismo package, as it includes stiffer shock absorbers and an improved engine cooling system, which is critical for aggressive driving.
Selection and service: what to look for
Buying a Z Series car requires careful preparation. Classic models 240Z and 260Z often suffer from corrosion, especially in the area of arches and sills. It is necessary to carefully inspect the body for signs of poor quality repairs or hidden rust.
For newer models 350Z and 370Z The main problems are timing chain stretching and failure of hydraulic compensators. It's also worth checking the condition of your limited slip differential (LSD), as it can be expensive to replace or repair. Regular Maintenance - the key to the long life of your sports car.
If you plan to use the car for track use, be sure to install a more efficient cooling system. Standard radiators may not be able to cope with prolonged loads, which will lead to overheating of the engine and transmission. It is recommended to check the condition of the brake discs and pads, as they wear out quickly during sports driving.
The most important thing when buying a Nissan Z is not only the condition of the engine, but also the absence of traces of serious accidents that could disrupt the geometry of the chassis.
Owners are often faced with the need to replace front suspension silent blocks. This is a consumable item that requires replacement every 40-50 thousand kilometers to maintain control accuracy. It is also worth paying attention to the cooling system, checking the condition of the pipes and pump.
⚠️ Warning: Never ignore knocking sounds from the engine at idle speed. This could be a sign of problems with the hydraulic lifters or timing chain, which will ultimately lead to a major overhaul.
