The Datsun lineup, particularly the 240z and 510 models, has long been admired for its classic styling and race-ready potential. These lightweight, rear-wheel-drive cars came with solid engineering and a loyal following, making them ideal platforms for performance upgrades. Today’s Owners look to enhance handling, power delivery, and overall driving experience while preserving the character that makes these cars unique.
While Datsun vehicles were ahead of their time in many respects, decades have passed since their initial production. Technology has evolved, and so have the options available to enthusiasts aiming to extract the full potential from these machines. Upgrading with carefully selected 240z aftermarket parts can dramatically improve responsiveness, reliability, and the thrill of driving without compromising the car’s vintage appeal.
Essential Aftermarket Upgrades For Peak Performance
To elevate your Datsun’s performance, consider integrating these proven aftermarket components into your build:
1. Performance Carburetors Or EFI Conversion Kits
The original SU or Hitachi carburetors can feel sluggish or inconsistent under load. Upgrading to Weber DCOE carburetors or converting to electronic fuel injection (EFI) provides a smoother throttle response and better fuel control. EFI kits, like those from FAST or Megasquirt, allow for custom tuning and modern reliability while improving cold starts and drivability.
2. Upgraded Suspension Systems
Datsun’s stock suspension has aged, and many components are past their prime. Performance coilovers or lowering springs paired with upgraded bushings and sway bars make a dramatic difference. Brands like BC Racing, Techno Toy Tuning, and Tokico offer suspension options that tighten cornering and improve ride quality without making the car uncomfortable for street use.
3. High-Flow Exhaust And Headers
A quality exhaust system enhances airflow and lets the engine breathe freely. Installing aftermarket headers and a stainless-steel exhaust can improve horsepower and torque, especially when combined with intake upgrades. Look for mandrel-bent tubing and well-crafted flanges for a snug fit and long-term durability.
4. Brake System Upgrades
The factory drum or small-disc brake setups were sufficient in the 1970s, but modern traffic and spirited driving demand more. Performance brake kits with vented rotors, stainless lines, and multi-piston calipers provide better stopping power and heat dissipation. Wilwood and Silvermine Motors offer bolt-on upgrades specifically tailored to classic Datsuns.
5. Lightweight Aluminum Radiators
Overheating can be a significant concern in older engines. A lightweight aluminum radiator with electric fans helps maintain safe engine temps during demanding conditions. Brands like Mishimoto and Koyorad provide direct-fit radiators that improve cooling efficiency while keeping the engine bay looking clean.
6. Limited-Slip Differential (LSD)
An LSD can transform handling for drivers who aim to track their cars or push them hard on twisty roads. An LSD provides better traction during acceleration out of corners, reducing wheel spin and improving control. With the right setup, units from OS Giken, Quaife, or NISMO can be installed into existing R160 or R180 differentials.
Build With Purpose And Personality
Each upgrade adds a layer of personality to your Datsun and reflects your driving goals. Some drivers build their cars for weekend track events, while others enjoy the occasional spirited backroad cruise. Choosing the right combination of 240z body panels and parts allows the vehicle to respond as you envision, blending an old-school feel with updated performance.
Upgrading a classic is about refining its capabilities. With careful selection and installation, aftermarket parts help your car remain competitive, responsive, and enjoyable for years. Each bolt you turn brings the car closer to the machine you’ve always imagined it could be.
