Race-Ready Exterior with BRE Styling

This 510 isn’t just fast; it looks the part, too. Before receiving a fresh coat of paint, the body was outfitted with a complete BRE-style aero package, including a lightweight hood, aggressive front spoiler, sculpted valance, wide front fenders, and flared rear quarter panels. To keep weight to a minimum, the factory rear and quarter windows have been swapped for plexiglass replacements. A new windshield and window seals were also installed, ensuring this classic racer maintains a fresh and refined look.

Track-Tuned Suspension & Braking System

Rolling on lightweight 13-inch Rota wheels wrapped in Toyo Proxes R888R tires, this 510 benefits from a fully optimized suspension and braking system designed for serious track performance. The setup includes an Ermish/Penske B-Sedan racing shock package, adjustable front and rear coil-over springs, and an Ermish front and rear brake package. Additional enhancements include an Ermish CV kit, rear control arm mono-ball kit, and a lower control arm mono-ball kit, ensuring superior handling and durability. The Ermish rear sway bar kit, BRE 1 1/8-inch adjustable front sway bar assembly, and 1-inch knuckle risers contribute to exceptional cornering stability.

Heat-treated front ball joints, an adjustable steering rod kit, BRE-style tension control rods, and a reinforced steering box brace further refine the car's steering precision. Frame rail support plates, a custom drag/center link assembly, camber plates, and an upgraded idler arm with Delrin bushings complete the setup. The braking system is enhanced with braided stainless steel brake lines for improved pedal feel and durability.

Driver-Focused Interior with Safety Enhancements

Inside the cockpit, safety and performance take center stage. A fully integrated and powder-coated roll cage reinforces the chassis, while the interior features painted sheet metal for a minimalist, race-ready aesthetic. The driver sits in an OMP racing seat, gripping a lightweight OMP steering wheel. A custom-modified Z-car pedal assembly enhances driver control, while a Safe Craft fire suppression system adds an extra layer of safety. Power is supplied by a lightweight Braille battery with a secure mounting system, ensuring reliability on the track.

To keep lap times precise, this Datsun 510 is fitted with an AiM Solo2DL GPS lap timer and an AiM SmartyCam system, complete with an RPM overlay for real-time performance tracking.

High-Performance 1.8L Rebello Racing Engine

At the heart of this race-spec 510 is a high-revving 1.8-liter Rebello Racing-built inline-four, engineered for maximum output and durability. Key engine modifications include a ported and polished cylinder head for improved airflow, lightweight Traum pistons for high-rpm durability, and twin 44mm Mikuni side-draft carburetors for optimal fuel delivery. A custom intake manifold with isolators helps reduce heat soak, while heat-coated headers and a free-flowing 2.5-inch mandrel-bent exhaust system improve exhaust efficiency.

The drivetrain is enhanced with a Quarter Master race clutch kit, Koyo radiator for efficient cooling under race conditions, and a high-torque race starter for quick ignition. A Moroso overflow tank ensures consistent fluid management, while Earl’s braided fuel and oil lines maximize reliability. An FIA FT3-certified fuel cell with a bladder provides enhanced safety, and a newly installed wiring harness ensures seamless electrical performance.
