Description

Engine overview

VQ35DE is Nissan’s 3.5-liter DOHC V6 that put Infiniti G35 and 350Z on the map. This listing is a 2003–2004 G35 engine with a six-speed manual, JDM as described, with source reference 823512A. DE is the earlier VQ35. HR arrived later with a different oil pump and a different personality. Mixing them without the matching electronics is unpaid labour.

Typical applications

Listed application window: 2003–2004 Infiniti G35. Year/make/model get you onto the right aisle. VIN, oil pan, and engine code decide whether the assembly actually ships.

Engine configuration

3.5L DOHC V6, Naturally aspirated, DOHC, 4 valves per cylinder, Aluminum block, Aluminum head. Listed dress: complete engine. Listed transmission: 6-speed manual. Published family output: 280–298 hp class depending on year and tune. That is not a dynamometer result for this serial.

What buyers should verify

Stamped engine code, oil pan shape, engine mounts, exhaust manifolds or turbo/blower hardware, and whether the harness and ECU in the vehicle match this generation. Send this SKU with the VIN on an engine enquiry before freight is scheduled.

Included assembly information

This is an engine-and-transmission package as titled. Clutch or torque converter, shifter, and electronics may still live in the donor. Photograph-level dress is the contract; unnamed parts are not included.

Installation considerations

JDM engines often differ in harness connectors, emissions equipment, and mount geometry from the US-market equivalent. Budget for sensors, manifolds, and an ECU strategy that the vehicle actually has. Compression or leak-down data is supplied only if it is written on the order—do not assume a test sheet exists because the engine is imported.

Shipping considerations

Engine and transmission packages ship as freight on a pallet. Combined weight is higher than an engine-only crate. Confirm a shop dock or a residential liftgate when the address is collected. Transit time is quoted after the destination is known; it is not printed as a guarantee on this page.

Warranty information

Used JDM coverage is stated per engine at the time of sale. No blanket term, labor reimbursement, or return window is implied by this listing. Read the note on the order before freight is scheduled.

Confirm fitment before freight

Year range and application notes are a starting point. VIN, engine code, oil pan, harness, and included accessories still have to match the vehicle. Send this SKU with the VIN on a Request a Quote form. For identification steps, read how to find the right replacement engine and used vs remanufactured engines.
