Vehicle Fitment

This engine is a direct replacement for the following North American models:

Mazda MPV (LX, ES, LX-SV): 2002, 2003, 2004, 2005, 2006
Note: This is the 3.0L V6 version. If you have a 2000-2001 MPV, you likely have the 2.5L GY-DE engine; please verify your engine size before ordering.

Important Installation & Swap Notes

To ensure 100% compatibility with your US-spec Mazda MPV and to satisfy emissions requirements, you must transfer the following components from your original engine to the JDM long block:

Intake Manifold & Throttle Body: To match your specific vacuum and sensor harness.
Exhaust Manifolds: To ensure fitment with your catalytic converters.
Engine Sensors: Including Camshaft (CMP) and Crankshaft (CKP) sensors.
Alternator & A/C Compressor: Use your original accessories to guarantee belt alignment.
Oil Pan: Inspect the JDM oil pan; some variants require swapping your original pan to clear the MPV subframe.

Recommended Maintenance: We strongly advise replacing the Water Pump, Thermostat, Spark Plugs, and Front/Rear Main Seals prior to installation for long-term reliability.

What is included

You receive exactly what is pictured. Engines are supplied as a long block assembly with the components visible in the photos. Accessories such as the alternator, starter, intake manifold or sensors are included only where you can see them on the unit, so check the photographs before ordering and ask us if anything is unclear.

Before you order

Confirm the engine code against your own vehicle, not just the model year.
Japanese market units can differ from the US version in intake, loom and sensors.
Replace the timing components, water pump and seals while the unit is out. It is cheap insurance on an engine this age.
Keep your original accessories until the swap is finished and running.
