Need an Engine Type VQ35DE for Nissan Maxima 2007 Nissan Maxima, chances are you’re dealing with a failing or dead engine—or you’re restoring one for performance or resale value. Either way, you’re about to make a significant investment. And if you’re like most people diving into engine replacement for the first time, it can be an overwhelming world of acronyms, fitment issues, compatibility concerns, and aftermarket risks.

This guide is designed to demystify that process.

As someone who has rebuilt and replaced engines professionally for over a decade—and made just about every mistake in the book—I’ll walk you through exactly what you need to know before you buy a VQ35DE engine for your 2007 Maxima. That includes which VQ35DE variant fits, where to buy it, red flags to avoid, and how to make sure you’re not wasting your time or money.

Let’s get into it.

What Is the VQ35DE Engine, and Why Does Your Maxima Need It?

The VQ35DE is a 3.5L V6 engine designed by Nissan and is part of their award-winning VQ-series family. Introduced in the early 2000s, the VQ35DE has powered multiple Nissan and Infiniti models—from the Altima and Maxima to the 350Z and G35. But not all VQ35DEs are created equal.

Engine Specs Overview

In the 2007 Nissan Maxima, the VQ35DE engine came mated with either a CVT transmission or a five-speed automatic, depending on trim level. And while it shares a name with other Nissan 3.5L V6 engines, there are crucial differences in ECU tuning, sensors, mounts, manifolds, and emissions equipment.

Not All VQ35DE Engines Are Interchangeable—Here’s Why

It’s tempting to think you can just grab any VQ35DE from a salvage yard and drop it in. Wrong move.

Variants and Compatibility

The VQ35DE has multiple generations and tuning versions depending on the vehicle and year. For example:

• The 2002–2004 Maxima had a different intake manifold and ECU.

• The 2005–2006 version began using CVT compatibility modules.

• 2007 introduced more advanced emissions controls—so plugging in an older engine often triggers CELs (check engine lights) or fails to communicate properly with the car’s computer.

Key Differences to Watch Out For

1. Wiring Harness and ECU Compatibility – The 2007 Maxima has updated connectors and sensors.

2. Motor Mount Brackets – Some VQ engines have different mount points (especially from the 350Z or Pathfinder).

3. Emissions Equipment – California-spec engines may have additional EGR components.

4. Cam/Crank Sensor Location – Some older VQs have sensors in different spots or with different pins.

Bottom line: Stick with a 2007 Maxima VQ35DE if possible. If using another donor, verify part numbers, sensors, and mounts carefully.

Should You Buy a Used, Rebuilt, or Remanufactured Engine?

This is one of the most important decisions you’ll make. Let’s break it down:

1. Used Engines (JDM or Salvage)

Pros:

• Cheapest option (can find engines for $900–$1500)

• Quick availability at local yards

Cons:

• Unknown mileage and wear

• Often no warranty or only 30-day limited

• Might require swapping sensors or parts from your old engine

2. Rebuilt Engines

Pros:

• Repaired with new seals, gaskets, and cleaned internal components

• Generally comes with a 6-month to 1-year warranty

• Cheaper than new but more reliable than used

Cons:

• Depends on who rebuilt it—quality varies widely

• Not always “fully refreshed” internally

3. Remanufactured Engines (Best Option)

Pros:

• Rebuilt to OEM or better specs

• Usually includes upgraded components like forged pistons or coated bearings

• Long warranties (1–3 years, some unlimited miles)

Cons:

• Higher cost ($2500–$4000)

• May have longer lead times

💡 Pro Tip: If you’re replacing a 2007 Maxima engine for long-term use, remanufactured is the safest bet. For a quick flip or temporary use, a clean used engine might suffice.

Where to Buy a VQ35DE Engine for a 2007 Nissan Maxima

Your source matters more than you think. Let’s look at your best options:

1. Local Salvage Yards

Search for cars with rear-end damage, indicating the engine likely wasn’t hit.

• Ask for compression test results.

• Get the VIN of the donor car and verify year and model.

• Be cautious of mileage claims without documentation.

2. Online Engine Retailers (2025 Update)

• SWEngines.com – Offers used and rebuilt VQ35DEs with warranty

• JDM Engine Depot – Great for imported VQs (watch for emission differences)

• LKQ Online – Nationwide availability with part matching

• Powertrain Products Inc. – Offers remanufactured long blocks with excellent warranties

3. Nissan Dealership (Rarely Worth It)

• Expect prices above $6000

• Only viable for those seeking OEM authenticity with factory warranties

Things You MUST Check Before Installing the Engine

Whether you’re doing the job yourself or hiring a mechanic, you’ll save a lot of time and headaches if you follow these steps:

Pre-Installation Checklist

• ✅ Inspect engine compression (ideal: 180–200 psi per cylinder)

• ✅ Check oil pressure and leak test gaskets

• ✅ Swap your old intake manifold, throttle body, and fuel rails if needed

• ✅ Replace timing chain guides and tensioner (common VQ failure point)

• ✅ Install new spark plugs, gaskets, and motor mounts

🔧 Even if the engine looks “plug and play,” always assume some parts will need swapping for compatibility.

Final Thoughts: Is Replacing Your Maxima’s Engine Worth It?

That depends on what the car means to you. The 2007 Maxima is a comfortable, powerful sedan with a loyal fanbase—but it’s not considered a collector’s item. If your Maxima has a clean body, solid transmission, and emotional value, replacing the engine with a reliable VQ35DE makes perfect sense.

But if your transmission is also failing, the interior is falling apart, or rust is eating the subframe, it might be time to move on.

FAQs – Need an Engine Type VQ35DE for Nissan Maxima 2007

Q: Can I use a VQ35DE from a 350Z or Altima in my 2007 Maxima?
A: Technically yes, but you’ll likely need to swap sensors, intake manifold, and possibly wiring harnesses. Always verify with a professional.

Q: How do I know if the engine I’m buying is the right VQ35DE version?
A: Check the engine number tag (usually near the bellhousing) and match it with your VIN’s engine code. Always cross-reference with your Maxima’s ECU compatibility.

Q: Are JDM VQ35DEs a good choice?
A: They can be—especially if mileage is low—but watch out for emissions incompatibilities and different mounting setups. You might need to reuse parts from your old engine.

Q: Is it cheaper to rebuild my existing engine instead?
A: Sometimes. If the block and heads are salvageable, a local shop may rebuild it for $2,000–$3,000. But expect delays and unexpected parts costs.

Q: Do I need to reprogram my ECU when swapping the engine?
A: If you’re installing the same engine year and model, usually not. But if sensors or emissions parts differ, yes—flashing the ECU or swapping it might be necessary.
