2004 Used Nissan Engines For Sale

Every 2004 Nissan engine we hold today, sorted by engine code rather than by badge, because 2004 is a changeover year. It is the last year of the 3.3L V6 and the 2.4L truck four, and the first year of the 5.6L V8, so the trucks on this page share almost nothing with the 2005 ones. Each unit is VIN-matched, ASE-tested and photographed before it ships.

One further row sits under vendor Nissan as "Pathfinder Armada" carrying 3.5L VQ35DE VIN D specifications. The Armada is a 5.6L V8 vehicle, so the nameplate and the specification do not agree; the row is counted in the family table and kept out of the model tiles rather than reassigned. Text the VIN to +1-307-441-5554 and we will confirm what the unit is.

Why Buy a 2004 Nissan Engine from Auto Power Source

2004 is a handover year on the Nissan truck line, and that is the single most useful thing to know before you buy. The Frontier and Xterra run the 3.3L VG33E at VIN E, the supercharged VG33ER at VIN M and the 2.4L KA24DE at VIN D. All three end with this model year: from 2005 the same two vehicles take the 4.0L VQ40DE and the 2.5L QR25DE instead. A 2005 truck engine will not substitute for a 2004 one, whatever the listing search suggests.

The supercharged 3.3L deserves naming on its own. It is the same VG33 block as the VIN E unit but it is not the same engine to buy: lower compression, its own intake tract, supercharger drive and boost plumbing. We hold the two as separate family rows and never offer one as a replacement for the other. The 4th VIN digit is what separates them, E against M.

The 3.5L VQ35DE is the code that covers the most ground on this year, and it is one code in two installations. Transverse in the Murano, Quest, Maxima and Altima 3.5; longitudinal in the Pathfinder and the 350Z. The oil pan, sump, brackets and intake routing differ between the two, so we hold them as separate rows and label each by the donor vehicle's layout rather than by displacement.

The 5.6L VK56DE arrives in 2004 with the Titan and the Armada, both brand-new nameplates. Unlike the later years on this brand, both 2004 rows carry the printed VK56DE code rather than a bare fuel letter, so there is nothing to read across and nothing to infer. The 350Z splits a different way again: two units, same 3.5L code and the same VIN A, divided only by build date, thru 9/03 and from 10/03.

Every engine here is used OEM from a low-mileage donor vehicle, compression-tested cylinder by cylinder with a leak-down evaluation, photographed from multiple angles for your approval before it leaves the warehouse, and shipped free with up to a 3-year warranty. We match the donor VIN to your VIN internally so the calibration, emissions package and gearbox pairing line up.

Your 2004 Nissan Engine Options: Compared

Most 2004 Nissan owners face four real choices when the engine fails:

← Swipe sideways to see all columns →
Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High — tested Included VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt
Junkyard $ Cheapest Unknown None DIY

Tested used OEM hits the sweet spot — same engineering as new, fraction of the cost.

2004 Nissan Engine Buying Guide

5 things to verify before buying a used 2004 Nissan engine:

  1. Read the 4th VIN digit, then the code. On 2004 Nissan stock the 4th digit does most of the work but not all of it. Letter A alone covers the 5.6L VK56DE, the 3.5L VQ35DE and the 2.5L QR25DE, and letter D covers both the 3.5L Pathfinder and the 2.4L KA24DE truck four. Give us the printed code as well if your listing carries one.
  2. Settle the truck engine before you compare prices. A 2004 Frontier or Xterra is one of three things: 3.3L VG33E at VIN E, 3.3L supercharged at VIN M, or 2.4L KA24DE at VIN D. None of the three carries over to 2005, so a cheaper 2005 listing is not the same part.
  3. Do not treat the supercharged 3.3L as a 3.3L. The VIN M unit is supercharged, runs lower compression and has its own intake and boost hardware. It is not interchangeable with the VIN E engine in either direction, and we hold them as separate rows for that reason.
  4. Check the installation, not only the engine. A 3.5L VQ35DE out of a Pathfinder or a 350Z is mounted longitudinally; one out of a Murano, Quest, Maxima or Altima is transverse. Same code, different pan, brackets and intake routing. Tell us the donor model so the installation matches.
  5. Confirm the match with your own VIN before you order. Send us the VIN from your vehicle and we will confirm the engine, calibration and fitment against it before anything is picked or shipped. Text +1-307-441-5554 or call 1-877-313-8995.

Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.

Frequently Asked Questions

How many 2004 Nissan engines do you have in stock right now?
Twenty-five, and the page is generated from live active listings, so the family table and the model tiles always add up to what is actually on the shelf. Text the VIN to +1-307-441-5554 and we will confirm which of the twenty-five fit.
The 4th VIN digit on my 2004 Nissan is A. Which engine is that?
Letter A covers three unrelated engines on 2004 stock: the 5.6L VK56DE V8 in the Titan and Armada, the 3.5L VQ35DE in the Murano and the 350Z, and the 2.5L QR25DE in the Altima 2.5 and Sentra 2.5. The letter alone settles nothing, which is why we match on the full VIN.
What engine does a 2004 Frontier or Xterra take?
One of three: the 3.3L VG33E at VIN E, the same 3.3L supercharged at VIN M, or the 2.4L KA24DE at VIN D. We hold all three in live stock as separate family rows. Tell us the 4th digit and we will point you at the right one.
Can I fit a 2005 Frontier engine in my 2004?
No. 2004 is the last year of the 3.3L V6 and the 2.4L four in these trucks; 2005 moves to the 4.0L VQ40DE and the 2.5L QR25DE. The two model years do not share the engine, so a 2005 listing is not a cheaper version of the same part.
Is the supercharged 3.3L the same engine as the ordinary 3.3L?
Same VG33 block, not the same engine to buy. The VIN M unit is supercharged, runs lower compression and carries its own intake, supercharger drive and boost plumbing. We never offer one as a substitute for the other.
Why are there two 2004 350Z engines with identical specifications?
Both are the 3.5L VQ35DE at VIN A. They are split by build date, thru 9/03 and from 10/03, which is a mid-season parts difference recorded on the listing rather than in the code. Tell us your build date or send the VIN and we will match it.
Do your 2004 Titan and Armada listings carry an engine code?
Yes, both do. Unlike the later years on this brand, where the 5.6L rows often show only a fuel letter, the 2004 Titan and Armada rows both print VK56DE at VIN A. 2004 is the first model year for both nameplates and for this engine.
Do you have a 2004 Pathfinder with a V8, or a 4.0L V6?
No. The 2004 Pathfinder is 3.5L VQ35DE only, at VIN D. The 4.0L VQ40DE starts in 2005 and the 5.6L V8 Pathfinder is a 2008 and later R51 variant. If you believe you have something else, text the VIN to +1-307-441-5554 and we will check it against the wider catalogue rather than guess.

Our 6-Step Inspection & Shipping Process

Every Nissan engine we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm the engine code (4th VIN digit), California vs federal emissions calibration, and drivetrain fit.
2. Tested & Verified
ASE-certified technicians compression-test every cylinder and run leak-down evaluation. Every 2004 unit is checked on the installation its donor used, the supercharged 3.3L is evaluated on its boost hardware as well as its compression, and the 3.3L, 2.4L and 5.6L rows are kept apart from their 2005 replacements before any unit is picked.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches internal wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: turbos, manifolds, valve covers, housings, accessories, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.

Our Photos-Before-Shipment Guarantee

Before any engine leaves our warehouse, we send you multi-angle photographs. You approve. If you do not approve, you get every dollar back — no questions, no restocking fees, no return freight charges. On top of 30-day money-back and the warranty included with every unit.
