Enthusiasts and collectors alike look to the 2004 model year for its balanced chassis, naturally aspirated V6 powerplant, and pure analog driving dynamics.
Understanding the precise engineering, dimensions, powertrain capabilities, and chassis metrics of the 2004 Nissan 350Z requires a deep dive into factory specifications. Whether you are evaluating a potential purchase, restoring a classic modern sports car, or tracking factory performance data, a comprehensive examination of the technical architecture is essential.
Powertrain and Engine Architecture
At the heart of the 2004 Nissan 350Z lies the acclaimed VQ35DE engine. This 3.5-liter (3,498 cc) 60-degree V6 features an aluminum block and aluminum cylinder heads, equipped with a DOHC (Dual Overhead Cam) layout utilizing four valves per cylinder. Nissan incorporated Continuous Variable Valve Timing Control (CVTCS) to optimize the intake valve timing, ensuring a broad and flat torque curve across the rev range.
The engine breathes through an electronically controlled throttle body and features a multi-point port fuel injection system. With a compression ratio of 10.3:1, the VQ35DE requires premium unleaded gasoline (91 octane or higher) to achieve its factory-rated output.
- Horsepower: 287 hp @ 6,200 rpm
- Torque: 274 lb-ft (371 Nm) @ 4,800 rpm
- Redline: 6,600 rpm (Manual transmission) / 6,200 rpm (Automatic transmission)
- Bore x Stroke: 95.5 mm × 81.4 mm
The engine bay layout features a front-midship engine placement, pushing the center of gravity closer to the center of the car for improved handling agility. A structural strut tower brace ties the front suspension towers together directly from the factory, enhancing chassis rigidity under heavy cornering loads.
Transmission and Drivetrain Options
The 2004 Nissan 350Z transferred power to the rear wheels via two transmission choices, tailored to different driving preferences.
6-Speed Manual Transmission
The close-ratio 6-speed manual transmission (manufactured by JK Technologies/Aisin) is the preferred choice for driving enthusiasts. It features direct mechanical linkage, a dual-mass flywheel, and optimized gear ratios that keep the VQ35DE engine in its optimal power band during aggressive driving.
5-Speed Automatic Transmission
An electronically controlled 5-speed automatic transmission with manual shift mode (Downshift Rev Matching in select trims) was available for buyers seeking daily-driving convenience without completely sacrificing manual control. While slower-shifting than modern dual-clutch units, this transmission handles stock torque levels reliably.
Both transmission options route power through an open differential on base models, while higher trim levels—such as the Enthusiast, Performance, Touring, and Track models—benefit from a viscous limited-slip differential (VLSD) to improve rear-wheel traction during acceleration out of corners.
Suspension, Steering, and Braking Systems
The chassis architecture of the 2004 Nissan 350Z relies on a FM (Front Midship) platform designed specifically for rear-wheel-drive sports car dynamics.
Suspension Layout
- Front: Independent multi-link suspension with coil springs, gas-pressurized shock absorbers, and a stabilizer bar.
- Rear: Independent multi-link suspension with separate coil springs and shock absorbers, plus a stabilizer bar.
This geometry provides exceptional camber stability and predictable handling characteristics, though factory alignment sensitivity can lead to inner tire wear if lowered or driven hard.
Steering
The steering system utilizes a vehicle-speed-sensitive rack-and-pinion setup with hydraulic power assistance. It offers direct feedback with approximately 2.6 turns lock-to-lock, ensuring sharp turn-in response and high-speed stability.
Braking Performance
Stopping power varies by trim level. Base and Enthusiast models feature standard ventilated disc brakes with single-piston sliding calipers. Higher performance trims—specifically the Track and Grand Touring models—come equipped with Brembo braking packages:
- Front Brakes: 12.8-inch ventilated discs with 4-piston opposing aluminum calipers.
- Rear Brakes: 12.7-inch ventilated discs with 2-piston opposing aluminum calipers.
- Safety Aids: Anti-lock Braking System (ABS) with Electronic Brake-force Distribution (EBD) and Brake Assist (BA) were standard across all trims. Vehicle Dynamic Control (VDC) and Traction Control System (TCS) were available on select models.
