2023 Nissan Z Proto Spec – SEMA-Displayed, Carbon-Fiber, E85-Tuned, 6-Speed Manual
This 2023 Nissan Z Proto Spec, presented in striking Ikazuchi Yellow Tricoat, was extensively upgraded for SEMA exhibition. It features a full Seibon carbon-fiber aero package, including the roof, rear hatch, vented hood, front spoiler, side skirts, rear diffuser, and wing, enhancing both aesthetics and performance.

Under the hood, the twin-turbocharged 3.0-liter VR30DDTT V6 is optimized with an AMS Performance E85 flex-fuel system, high-pressure fuel pump, EcuTek ECU calibration, AMS downpipes and exhaust, cold-air intakes, and upgraded intercoolers. Power is delivered to the rear wheels via a six-speed manual gearbox and a limited-slip differential.

The Z rides on 19-inch bronze RAYS forged alloy wheels wrapped in Bridgestone Potenza tires (255/40 front, 275/35 rear). Braking is managed by Akebono calipers (yellow-finished, four-piston front, two-piston rear) and vented discs. The chassis benefits from double-wishbone aluminum front and multi-link rear suspension, complemented by Vehicle Dynamic Control, Traction Control, Electronic Brake Force Distribution, and Brake Assist.

Inside, the cabin is appointed with graphite leather heated power seats, a 12.3-inch digital cluster, and a 9-inch touchscreen infotainment system supporting Apple CarPlay, Android Auto, and Bose audio. Additional amenities include Intelligent Cruise Control, automatic climate control, Active Noise Cancellation, Active Sound Enhancement, Lane Departure Warning, Blind Spot Warning, Rear Cross Traffic Alert, and yellow seatbelts. Note: minor scuffing is present on the driver’s door panel.

The vehicle currently shows 4,005 miles and was acquired by the selling dealer in 2025. It is offered with a clean Oklahoma title and a CARFAX report confirming no accident history, two previous owners, three service records, and one open recall.

This unique Proto Spec RZ34 blends show-quality modifications with factory performance and technology, making it an exceptional example for collectors and enthusiasts.
