Duratec year interchange

[kmfw]

Does anyone know for sure what years will fit in a 2005? Car-part has them listed for 2004-2006 and 2007+. In my area its cheaper to get a newer engine but I can't find what changed between 06 and 07.

Welcome to TRS

2002 and up Rangers had the Mazda L 23NS Duratec engines
2002 and up Mazda B2300 used the same engine

These engines showed up in Rangers in mid-2001, so you will see 2001 Duratec Rangers
But all 2002 and up had them

2001-2003 2.3l Duratec had Electric thermostat and IMRC(intake manifold runner control) these both needed computer feedback or control

2004 and up lost both the above, so 2004 2.3l and up computers are different that 2001-2003 computers

Any 2004 to 2012 23NS Duratec should/will work fine in your 2005, if you are willing to change some parts from one engine to the other.
Sensor plugs and placement change on the engines over the years, so a 2005 sensor plug might not fit on to the 2007 sensor, just swap sensor over, or sensor was moved so 2005 wire won't reach, extend the wire

The NS in 23NS stands for north south, it means the engines were mounted Rad to Firewall, and these engine were made in Dearborn, Michigan

Ford cars got the 23EW, east west, these engines were mounted wheel to wheel, transverse mounting, and made in Mexico

Ranger needs a 23NS not a 23EW

Thanks! picked up a lower mileage '09 engine today. Only major difference I can see are the fuel injectors and wiring harness plugs. I'm limited on time, was planning on swapping the harness but I don't want to pull the intake manifold to change injectors. Tried searching but cant find the differences in injectors other than part no. and color, Yellow vs. brown. Anyone know of the specs for ford injectors?

If you don't get an answer here, maybe try over on http://turborangerforums.com

Color indicates flow rate. Length and width indicate level of penile dissatisfaction of the guy designing the fuel rail and intake.

"They" do sell fuel injector adapter plugs, so you can change brands, you just need 4, and it may be easier than swapping harness

Depends on what you have room for

Thanks, think the injectors are mazda based so I can't find the info. Finished the swap and it runs but long term fuel trim is in the negative, -18%, so it looks like I'll be pulling the intake to change them out. Anyone else looking to do a similar swap the only other differences I've found are the wiring harness, cylinder head temp sensor and the casting for the upper coolant line doesn't have a spot for the coolant temp sensor. Only CEL was for it running rich, after clearing it hasn't come back on so the adaptive learning might be enough for the short term.
