About the Nissan 350Z Engine

This is the VQ35HR, the High Revolution version of Nissan's 3.5-liter V6, used in the later 350Z (2007 to 2008), as the live page describes. It builds on the VQ family with a stronger 60-degree aluminum block and aluminum heads, DOHC valvetrain with continuously variable timing on the intake (CVTC) and electronic timing on the exhaust (e-VTC), a higher 7,500 rpm redline, and refined internals for stable high-rpm running. Coil-on-plug ignition through the Nissan Direct Ignition System supports clean, efficient combustion, and the result is an engine with strong mid-range torque and an eager top end.

Why 350Z Owners Replace the Engine

High mileage, oil consumption, overheating, and bottom-end wear from hard use are the usual reasons. A healthy VQ35HR restores the 350Z's quick-revving response and broad power, brings back a smooth idle and confident throttle, and returns the car to track-capable form when properly maintained and cooled, with the engine inspected for compression before it ships.

Things to Confirm Before Ordering

• Your exact year, confirmed by VIN; this is the VQ35HR used in the 2007 to 2008 350Z, not the VQ35DE of the 2003 to 2006 cars
• Your transmission: per the live FAQ, the engine is compatible with both 6-speed manual and 5-speed automatic setups
• Your maintenance plan: per the live FAQ, use recommended synthetic oils and keep up timely valve adjustments to extend performance life
