The 1971 Datsun 240Z has always been an icon, but this example takes the classic Z-car formula into modern performance territory. The seller purchased this car in 2006 and embarked on a thorough resto-mod journey. This process involved far more than a simple refresh. The result is an RB25DET Datsun 240Z that beautifully blends vintage looks with turbocharged Japanese muscle. Finished in Bright Red over black vinyl, this car now carries a drivetrain borrowed from a Nissan Skyline GTS-t, making it a true performance hybrid.
Exterior and Aero Details
The body was expertly refinished in 2006 in a vibrant GM shade of Bright Red. This color perfectly highlights the 240Z’s timeless long hood, short deck profile. Exterior details are a mix of subtle aggression and modern utility. Black powder-coated bumpers provide a clean, contemporary contrast to the red paint.
Lighting and Aerodynamic Touches
The front end features a functional front splitter and a front lip spoiler. LED headlights with clear covers update the classic look while improving visibility. Further lighting updates include clear corner markers and modern LED taillights. The rear is finished with a black-finished lip spoiler and a single custom titanium exhaust outlet. Dual BRE side mirrors complete the focused, sporty exterior.
Chassis and Suspension Upgrades
The original chassis received significant attention to handle the increased power. The foundation includes Techno Toy Tuning control arms and a mustache bar. An aftermarket Motorsport Auto front sway bar enhances cornering stability. Front and rear strut tower braces further stiffen the chassis.
Coilovers and Stopping Power
The suspension relies on adjustable BC Racing coilovers at all four corners. This system allows for fine-tuning of the ride height and dampening. Replacement polyurethane bushings are used throughout the suspension. Braking performance is radically improved with front and rear Wilwood big brake kits. These feature red multi-piston calipers over slotted and cross-drilled rotors for consistent stopping power. The system also includes an adjustable proportioning valve.
Drivetrain: The Skyline Heart
The heart of this 240Z is the turbocharged 2.5-liter RB25DET inline-six. This engine was sourced from a Skyline GTS-t and installed in 2011. Power is managed by a five-speed manual transmission, also sourced from a Skyline GTS-t. The transmission sends power to the rear wheels via an R200 limited-slip differential.
Performance Enhancements
Several modifications support the engine’s power output and reliability. A front-mount air-to-air intercooler keeps the intake charge cool. A Tial blow-off valve manages boost pressure effectively. Cooling is further supported by an aluminum radiator and an electric cooling fan. The fuel system was addressed with a Walbro fuel pump and a refurbished fuel tank in 2025.
Custom Engine Bay Details
The engine bay is finished with polished aluminum charge pipes and a Vibrant catch can. A custom pie-cut titanium exhaust system provides a distinct sound and lightweight construction. The system also features a front-mount oil cooler and a remote spin-on oil filter. In 2025, the floorpans were replaced, and the underside received a rust inhibitor coating.
Interior and Modernization
The cabin maintains a purposeful look with crucial modern comforts. The bucket seats were retrimmed in black vinyl. This material is complemented by a color-coordinated replacement dashboard and carpets. Power windows were installed, adding convenience often missing in early Z-cars.
Instrumentation and Audio
The driver interacts with a three-spoke steering wheel. The original gauges are replaced by a full set of accurate Speedhut instrumentation. This includes a 160-mph speedometer and an 8k-rpm tachometer. AEM auxiliary gauges for boost, oil pressure, and oil temperature sit over the center stack. A Bluetooth-capable retro-look stereo linked to Pioneer speakers provides modern audio. The digital odometer indicates a low 7 thousand miles.
Power, Engine Specs, and Performance
The turbocharged 2.5-liter RB25DET inline six engine is paired with a five-speed manual transmission. This combination delivers significantly more power than the original 240Z engine. The high-revving turbo engine provides immediate boost and relentless acceleration. The extensive suspension upgrades, including adjustable coilovers and Wilwood brakes, ensure the chassis can fully utilize the extra horsepower. This resto-mod car offers a dynamic and modern driving experience packaged in a classic Japanese sports coupe body.
Summary of the RB25DET Datsun 240Z
This 1971 Datsun 240Z is a meticulously executed resto-mod that bridges five decades of performance technology. The swap to a powerful turbocharged RB25DET engine from a Skyline GTS-t transforms the coupe into a quick and capable machine. Complemented by full chassis upgrades, modern braking, and a refreshed interior, this Z-car is ready for modern roads. The Bright Red Datsun 240Z successfully honors its iconic past while embracing the excitement of custom Japanese performance.
