This gave drivers greater confidence when navigating tight corners or slippery surfaces. In addition, the use of lightweight materials helped keep overall mass low, which enhanced fuel efficiency and agility.
Furthermore, the independent suspension system played a crucial role in maintaining tire contact over uneven ground. Unlike many competitors that relied on rigid axles, the Datsun 510 Rally car used MacPherson struts up front and a four-link setup in the rear. This allowed each wheel to react independently to bumps and dips. Consequently, drivers experienced smoother rides and better control during high-speed sections. Even today, this suspension design is praised for its simplicity and effectiveness.
Performance Upgrades That Made a Difference
Engine Tuning and Forced Induction
Although the stock L16 engine produced modest power, tuners quickly discovered its potential for significant gains. By adding twin side-draft carburetors, high-lift camshafts, and free-flow exhaust systems, horsepower could be nearly doubled. Some advanced builds even incorporated turbocharging, pushing output well beyond factory limits. These modifications transformed the Datsun 510 Rally car into a surprisingly quick machine.
Additionally, engine reliability remained strong thanks to robust internal components. The iron block and forged crankshaft handled increased stress without frequent failures. As a result, teams could push the Datsun 510 Rally car hard throughout long-distance rallies. Cooling upgrades were also common, including larger radiators and electric fans to prevent overheating during extended climbs or desert stages. With these enhancements, the car became a consistent finisher rather than just a fast starter.

During the 1970s, the Datsun 510 Rally car dominated numerous regional and national rally championships in the United States. It frequently competed in Sports Car Club of America (SCCA) events, where its predictable handling gave drivers a major advantage. Privateers appreciated how easy it was to repair between stages, often using basic tools and spare parts sourced from junkyards.
Meanwhile, factory support from Datsun North America further boosted its competitiveness. Official service bulletins and performance kits made it easier for amateur teams to build reliable race versions. For example, limited-slip differentials and upgraded brakes became widely available. Because of this, the Datsun 510 Rally car appeared in nearly every class where compact sedans were permitted. Its consistency and affordability attracted a growing fan base across the country.
