Datsun 240Z & 510 JDM Guide: Classic Japanese Icons

How do prices compare between genuine Datsun models and modern reproductions?

Original Datsun 240Z and 510 models command significant premiums over modern kit cars or reproductions. An authentic 1970 240Z might cost $60,000-$100,000, while a new 240Z-inspired kit car costs $40,000-$80,000 before customization.

The Datsun 240Z: Japan's Answer to the Sports Car World

When the Datsun 240Z debuted in 1969, it shocked the automotive world. Priced at just $3,995 USD—less than half the cost of a Porsche 911—the 240Z offered genuine sports car performance wrapped in an affordable package. The Datsun 240Z JDM wasn't just a car; it was a revolution that proved Japanese manufacturers could compete with European and American sports cars on every level.

Performance Specifications and Engine Details

The original Datsun 240Z featured a 2.4-liter inline-six engine (L24 engine code) producing 151 horsepower and 146 lb-ft of torque in its initial 1969-1970 form. By 1971, Nissan bumped power to 160 horsepower, making it one of the most powerful naturally aspirated six-cylinder engines of its era. This engine paired with either a 4-speed manual or 3-speed automatic transmission, though true enthusiasts always preferred the manual.

Engine displacement: 2,393cc (2.4L inline-six)
Horsepower: 151-160 hp depending on year and market
Torque: 146-159 lb-ft
0-60 mph: 8.0-8.3 seconds (excellent for 1969)
Top speed: 125 mph
Weight: 2,400 lbs
Fuel economy: 18-22 mpg

Design and Build Quality

Designed by Yoshihiro Matsuo and produced by Nissan's Oppama Factory in Japan, the 240Z featured a long hood, short deck proportions that borrowed inspiration from the Jaguar E-Type. The lightweight steel chassis and fiberglass-reinforced body panels kept weight minimal. Interior appointments included leather seats, full instrumentation, and a surprisingly comfortable driving position that made the datsun jdm enthusiast vehicle equally suitable for daily driving or weekend spirited drives.

The Datsun 510: The Affordable JDM Sedan That Changed Everything

While the 240Z grabbed headlines as a sports car, the Datsun 510 JDM quietly became the most transformative vehicle in Japanese tuning culture. This humble sedan, produced from 1968-1974, became the foundation for countless drift, street racing, and tuner builds that would eventually define 80s JDM culture. Today, a clean Datsun 510 in good condition sells for $12,000-$35,000 USD, with fully restored examples commanding even higher premiums.

510 Engine Options and Performance

The Datsun 510 came with several engine options depending on market and year. The most common JDM variants included the L16 (1.6L) producing 96 horsepower and the L18 (1.8L) generating 115-125 horsepower. What made the 510 special wasn't raw power—it was its potential. The lightweight, compact design and responsive handling made it the perfect platform for modification.

L16 engine: 1,595cc, 96 hp, 99 lb-ft torque
L18 engine: 1,770cc, 115-125 hp, 107-118 lb-ft torque
Curb weight: 2,100-2,300 lbs
0-60 mph: 10.5-12 seconds (stock L18)
Chassis code: S10
Production years: 1968-1974

Why the 510 Became a Tuning Legend

The Datsun 510's genius lay in its combination of simplicity and capability. The chassis was inherently well-balanced, the engine bay had plenty of room for upgrades, and the entire platform was so popular that the aftermarket quickly developed comprehensive modification options. By the 1980s and beyond, the 510 became synonymous with JDM street racing and drift culture, making it arguably the most important vehicle in establishing Japanese tuning as a serious automotive pursuit.

Historical Context: The 80s JDM Connection

Understanding 80s JDM culture requires recognizing how the 240Z and 510 paved the way for everything that came after. While these cars were produced in the late 1960s and early 1970s, they remained popular in the used market throughout the 1980s, when JDM tuning culture truly exploded. Modified Datsuns—particularly 510s—populated Tokyo's street racing scenes and became the training ground for drivers and mechanics who would later build the Skyline, Supra, and RX-7 dynasties.

Market Availability in Japan During the 1980s

In the 1980s, used Datsun 240Z models could be found throughout Japan for ¥800,000-¥2,500,000 ($4,000-$12,500 USD equivalent), while the more affordable 510 models ranged from ¥300,000-¥1,200,000 ($1,500-$6,000 USD equivalent). This accessibility meant thousands of young enthusiasts could modify and race Datsun-powered vehicles, creating an entire ecosystem of tuning shops, parts suppliers, and performance specialists that defined the era.

Frequently Asked Questions About Datsun 240Z and 510 JDM Models

What's the difference between Datsun and Nissan branding on these vehicles?

"Datsun" was Nissan's brand name until 1983. All Datsun 240Z JDM models and 510s were manufactured by Nissan. In 1983, Nissan officially retired the Datsun badge outside Japan, though these early models are forever known by their Datsun nameplate. For collectors, the Datsun branding adds historical authenticity and value compared to later Nissan-badged versions.

Are original Datsun 240Z models reliable for regular driving?

With proper maintenance, a well-restored Datsun 240Z can be quite reliable. The L24 engine is inherently robust, though 50+ year-old electrical systems, seals, and gaskets require attention. Most owners modernize fuel systems, ignition components, and wiring for improved reliability while maintaining original appearance. Plan for occasional surprises with age-old components, and budget accordingly for preventative maintenance.

Should I buy a stock or modified Datsun 510?

This depends on your goals. Stock or minimally-modified Datsun 510 JDM examples appreciate better as collector cars and appeal to purists. Well-executed modifications honoring the car's tuning heritage can be satisfying to own and drive, but resale value becomes highly dependent on the quality and authenticity of modifications. Document everything if purchasing a modified example, and buy based on current condition rather than promised future value.

Where can I source parts for restoration?

The datsun jdm community is well-served by specialty suppliers. Z-Car specialty shops (since these 240Z models are often called "Z-Cars") provide NOS (new old stock) and reproduction parts. For 510 models, the tuning community has extensive reproduction options. Online marketplaces like eBay, specialized forums, and Japanese suppliers still stock parts. Japanese import wrecking yards occasionally have complete cars that yield hard-to-find components. Expect to pay 20-40% premiums for authentic NOS parts compared to reproductions.

What's the best way to export a Datsun 240Z or 510 from Japan?

Japan has specific regulations about exporting vehicles. Generally, cars at least 30 years old can be imported to the United States more easily than newer vehicles. Work with established exporters familiar with Datsun models and understaffed with documentation requirements for your destination country. Expect total export costs between $3,000-$8,000 USD including inspection, shipping, and documentation. Many international JDM specialists facilitate these exports and can guide first-time buyers through the process, including compliance with EPA and DOT regulations.
