1973 | Datsun 240Z
Technical Information
Overview
This 1973 Datsun 240Z has undergone a comprehensive mechanical and cosmetic restoration, with significant work performed by Datsun Spirit, Inc. and BlackWolf. The restoration included an upgraded Stage II engine build, featuring an F54 block, 86mm DSI pistons, L28 rods, and an N47 cylinder head shaved for a high-compression setup. A Stage II camshaft was installed to enhance performance, and the engine was meticulously tuned for optimal reliability and power delivery. Supporting modifications included a used five-speed transmission sourced from a 1978 280Z, installed alongside the rebuilt engine to improve drivability and gearing. Complementing the powertrain overhaul, the steering system received new rack and pinion boots, with a full inspection of ball joints, tie rod ends, and bushings.
Beyond the drivetrain, the restoration encompassed brake and suspension upgrades to modernize handling and safety. The front brakes were upgraded with four-piston calipers and braided brake lines, significantly improving stopping power. A complete front-wheel alignment was performed to fine-tune handling dynamics. Additional invoices show a comprehensive repaint and body restoration, the 240Z was stripped down, repaired for any imperfections, and repainted to a high standard in Ferrari Rosso Corsa. The detailed bodywork restoration ensures that the classic lines of the 240Z remain in pristine condition while maintaining the car’s original aesthetic appeal.
With over $10k invested in the engine rebuild alone and many 10's of thousands more in additional work covering suspension, chassis, braking, and cosmetic refinements, this 1973 Datsun 240Z is a well-sorted and beautifully restored example of one of Japan’s most iconic sports cars. Whether you’re looking for a vintage sports car with modernized performance or a meticulously restored collector’s piece, this 240Z is an exceptional opportunity to own a piece of automotive history with documented restoration work. It is now offered with a Seller's Disclosure report and a clean title.
