When it comes to the golden age of Japanese automobile manufacturing, the name Nissan 260 Z comes to mind immediately after the classic models 240Z. This car was not just an evolution of design, but a real breakthrough in balancing power and handling. Many enthusiasts mistakenly believe that the difference between models lies only in engine size, but history 260 Z much deeper and more interesting.
Owners of these cars are often faced with the need to find rare spare parts and a deep understanding of the engineering solutions of the late 1970s. You are not just buying a vintage car, you are purchasing a piece of history that requires special treatment and professional service. L26 engine became the heart of this model, providing the same linear traction for which Nissan Z loved all over the world.
In this article we will look at the technical nuances that distinguish 260 Z from predecessors and successors. You'll learn what to look for when inspecting the body, how to properly set up carburetors, and why some owners choose this particular modification for track or collecting. Ready to immerse yourself in the world of classic Japanese car manufacturing?
History of creation and place in the Z line
Model range Series 2 was presented to the public in 1973, marking a new stage in the development of the company's sports coupe Nissan. Engineers were faced with the need to increase engine displacement to meet new environmental standards and market demands, which led to the emergence of a 2.6-liter engine.
The main goal of the designers was to maintain the lightness of the structure while increasing torque. As a result, 260 Z received an improved cooling system and a modified suspension. These changes allowed the car to remain at the top of sales, despite growing competition from European brands. Episode 2 became a bridge between the classical 240Z and more powerful 280Z.
It is important to note that this version did not last long in production, making it highly sought after by collectors today. In the USA the car was sold under the name Datsun 260Z, and in Japan and Europe - as Nissan. This duality in branding often confuses newbies trying to find original car documents.
If you are planning a purchase, be sure to check the VIN to ensure the authenticity of the model. The market is filled with restored examples, where the body parts may be from other versions. L26 engine has unique cylinder block markings that serve as the main identifier of authenticity.
Technical characteristics and L26 engine
With my heart Nissan 260 Z is the legendary inline six-cylinder engine L26. This power unit developed a power of about 165 horsepower, which was considered an excellent indicator for that time. A design feature is the use of two carburetors Shiroki or Hitachi, configured for smooth fuel supply.
Unlike later versions with electronic injection, L26 requires regular adjustment and cleaning of carburetors. Owners should be prepared that cold starts may take longer if the idle system is not adjusted perfectly. Torque 216 Nm is available from low revs, which makes acceleration pleasant and predictable.
The lubrication and cooling system has been redesigned to cope with the increased engine capacity. The radiator has larger honeycombs, and the oil pump is capable of pumping more fluid under pressure. However, wear of gaskets and seals over time becomes a critical problem, requiring a complete engine roll-out.
The table below shows the main differences between the motor installation 260 Z from previous version:
| Parameter | Nissan 240 Z (L24) | Nissan 260 Z (L26) | Note |
|---|---|---|---|
| Working volume | 2,393 cu.m. cm | 2,565 cu.m. cm | Increase due to piston stroke |
| Power (US) | 151 hp | 165 hp | Differences in carburetor settings |
| Compression ratio | 9.0:1 | 8.5:1 | Reduced for environmental standards |
| Carburetors | 2x Hitachi | 2x Hitachi / Shiroki | Modified jets |
Series 2 body and design features
Appearance 260 Z underwent noticeable changes compared to the Series 1. The headlights received larger lenses, and the rear of the car was modified to accommodate new lights. These changes were dictated not only by aesthetics, but also by safety requirements.
Body panels Series 2 have a different shape of wings and hood, which complicates the process of replacing parts during repairs. You can't just take wing from 240Z and install it on 260 Z without modifications. Windshield It also became taller and more curved, improving driver visibility.
The interior has received an updated dashboard with more readable dials. The steering wheel has become three-spoke, giving the cabin a more sporty look. However, the finishing materials remained the same: leather and wood, characteristic of cars of that time.
When inspecting the body, pay special attention to the sills and arches, as they are susceptible to corrosion due to road chemicals. Unique feature rear bumper 260 Z is the presence of additional amplifiers that are not present on earlier versions. This makes the rear end more durable in small collisions.

Suspension and handling
Suspension Nissan 260 Z built according to the classical scheme: independent at the front on double wishbones and semi-independent at the rear on torsion bars. This configuration provides excellent handling, but requires regular checking of the silent blocks and springs.
Owners often complain about the stiffness of the rear suspension, especially on rough roads. This is due to the fact that torsion bars lose their elastic properties over time. Replacing them with new original parts can radically change the behavior of the car on the road. Wheel alignment it is necessary to carry out specialized equipment, since standard angles may not be suitable.
The steering has a rack and pinion mechanism, which provides a clear response to steering wheel turns. However, wear of the rack over time leads to the appearance of play. Adjusting the clearances in the steering rack is a complex procedure that requires precision and experience.
To improve performance, many enthusiasts install a sport stabilizer bar. This reduces body roll when cornering and increases stability during emergency maneuvering. However, it is worth remembering that oversimplification of the suspension can reduce ride comfort.
☑️ Checking the suspension before the trip
⚠️ Attention: Do not ignore squeaks in the rear suspension! This may indicate destruction of the torsion bars, which will lead to loss of control at high speed.
Operation and Maintenance
Service Nissan 260 Z requires regularity and attention to detail. The engine oil must be changed every 5,000 km, using high-quality synthetics or semi-synthetics that meet the tolerances API. The cooling system requires periodic replacement of antifreeze and checking the hoses for cracks.
Carburetors need to be cleaned and adjusted every 10,000 km. Use a special cleaner and tool kit to fine-tune the mixture. Incorrect settings may result in excessive fuel consumption or loss of power. Spark plugs should be checked every 3000 km, changing them when carbon deposits appear.
Brake system 260 Z equipped with disc brakes at the front and drum brakes at the rear. Pads and discs wear out faster than on modern cars, so they need to be checked before every long trip. The brake fluid should be changed every two years.
To store your car in a garage, it is recommended to use a cover that protects it from dust and moisture. Indoor air humidity should not exceed 50% to avoid corrosion of metal parts. Battery It is better to remove it for the winter and store it in a warm place.
