Datsun Buyer’s Guide: What to Know Before You Build

TL;DR

• Choose Wisely: Series 1, 2, or 3? Each has pros, cons, and a unique appeal.

• Inspect Thoroughly: Look for rust, frame integrity, and original components before committing.

• Plan Your Build: Decide between OEM+, restomod, or full custom, and budget for engine, suspension, and brake upgrades.

Why the Datsun Series Remains a Must-Build Classic

Few cars have left as lasting a mark on automotive history as the Datsun 240Z. Introduced in 1969, it wasn’t just Nissan’s first true sports car—it was Japan’s bold statement to the world that performance, style, and affordability could coexist. Lightweight, sleek, and surprisingly agile, the 240Z instantly captured the imagination of enthusiasts, transforming the Japanese sports car into a global phenomenon.

Today, decades later, the allure of the 240Z remains stronger than ever. Collectors prize its timeless design, tuners embrace its adaptable chassis, and father-son duos like Chris and Royce Raquel continue to find inspiration in its combination of classic lines and mechanical purity. But buying and building one isn’t as simple as spotting a clean body online—it requires research, planning, and a clear vision for the type of project you want to pursue.

Whether you’re considering a Series 1 model for an OEM+ restoration, a Series 2 for a period-correct restomod, or a full custom build that blends old-school style with modern performance, this guide will walk you through everything you need to know. From spotting rust to choosing an engine setup, suspension upgrades, and interior finishes, we’ll cover the critical steps to ensure your 240Z build is both rewarding and successful.

By the end of this article, you’ll have a complete roadmap to make informed decisions, avoid common pitfalls, and start your own 240Z project with confidence—ready to honour the legacy while creating a car uniquely yours.

Understanding the Datsun Models

The Datsuns, introduced in 1969, became an instant classic thanks to their combination of lightweight chassis, sleek styling, and affordable performance. Knowing which model to buy is crucial:

• Series 1 (1969–1970): The purest classic, with smaller bumpers, cleaner lines, and highly collectable. Perfect for OEM+ builds.

• Series 2 (1971–1973): Slightly larger bumpers, minor interior updates, slightly less rare but easier to find replacement parts.

• Series 3 (1974): Transitional model, less desirable for purists but can be a solid restomod base.

Chris and Royce Raquel opted for a Series 1 due to its authenticity, timeless styling, and direct connection to their Japanese inspiration.

Inspecting a Datsun Before Purchase

Buying a 240Z isn’t just about looks—condition matters:

1. Rust Check: Look at the battery tray, sills, floor pans, and rear wheel arches. Rust is the biggest challenge in older cars.

2. Chassis and Frame: Ensure structural integrity; bent or weakened frames can make a restoration nearly impossible.

3. Engine and Transmission: Check for leaks, smoking, and unusual noises. Decide if you want the original L24/L26/L28 or plan an upgrade.

4. Suspension and Brakes: Inspect original components; many require upgrades for modern driving reliability.

5. Interior Condition: Seats, dash, and gauges affect both aesthetics and driving experience. OEM+ projects often retain original features with subtle modern enhancements.

Planning Your Build: OEM+, Restomod, or Full Custom

Before you start, decide how far you want to go:

• OEM+: Subtle upgrades that preserve the car’s original beauty while enhancing performance and reliability. Ideal for purists.

• Restomod: Period-correct styling combined with modern engines, brakes, and suspension. Balanced approach for performance and usability.

• Full Custom: Complete freedom for widebody kits, turbo swaps, and track-focused modifications. Most expensive, but maximises individuality.

Chris and Royce followed an OEM+ philosophy, preserving the Series 1’s clean lines while upgrading engine, brakes, and suspension for modern performance.

Engine and Performance Considerations

The L28 engine is the most common swap, offering excellent reliability and tunability. Common upgrades include:

• Triple Mikuni carbs for analog responsiveness

• Stroker kits for more displacement and torque

• Fujitsubo or equivalent exhausts for classic sound and improved airflow

• R200 differential upgrades for drivability and traction

Suspension, brakes, and tires must be upgraded to match the engine’s performance:

• BC Racing coilovers for adjustability

• Wilwood big brake kits for stopping power

• Z Forged or classic wheels with period-correct or sticky tires

Budgeting and Pitfalls

A Datsun build requires financial planning:

• Purchase price: $30k–$100k+ depending on condition and model

• Restoration parts: rust repair, suspension, engine, brakes

• Labour: professional alignment, fabrication, or engine work

Common pitfalls include: underestimating rust repair, over-modifying the car beyond its character, or skipping proper research on sourcing authentic components.

Final Thoughts: Building a Legacy

Owning and building a 240Z isn’t just a hobby—it’s a connection to Japanese automotive history. From Hakone drives to Devil Z inspiration, every choice in your build should honour the car’s heritage while reflecting your personal style.

Chris Raquel sums it up: “The 240Z is more than a car—it’s a story, a memory, and a legacy. Build it right, and it will give back a lifetime of experiences.”
