4x4 4.0 to 2.3 Duratec Swap

[Zander]

Dont forget you need the wiring and ecu. Some parts of the harness will swap over but alot will need to be changed. And the ecu's are obviously not interchangeable. You'll also need to do AC lines, coolant lines, exhaust etc. Cost and work wise you're going to be in as deep as a 5.0 swap (plus the trans work).

And for what its worth my duratec gets good highway mileage 25+ but city driving it barely gets 15...

Huh that's weird, my 2.3 lima is the opposite it gets 23 around town and 23 on the highway lol. What rear end gear does yours have? Mines a 4.10.

I would buy a '02 Ranger with as many of the features as you can get to match - air, cruise, manual, etc.

In addition to the engine and transmission, wiring and ecu, there's things like PATS, which leads to door locks and tachometer for which you'll want the entire display; that you would want.

It's very much the converse of the 5.0 - down 2 cylinders rather than up. And 5.0 includes transmission/transfer case work - a 135x never bolts direct to AODE or M5OD-R2. Effort/cost being more/less equal...

OK thanks that's a good idea, I don't think he's going to try it unless he gets an entire donor truck. To be honest if it was my truck I'd just rebuild the motor that's in there sounds like way too much work to me, but my buddy likes doing this stuff more than myself and is better at it.
