4.0 to 4.0 swap

[snoopdoggie]

Will a '94 Explorer 4.0 function in a '92 Explorer? I can swap the intake and exhaust to remove the EGR but I'm unsure about the Cam Sensor. Just leave it in or pull it out?

I'd remove the cam sensor and replace it with the oil pump drive from an earlier engine because they are mechanically failure prone as well as electronically failure prone

Swap your exhaust manifold, upper intake AND injectors onto the "new" engine.

the injectors are different on a '93-94 and there is other stuff you'd have to change tob e able to run them without issue.

Frankly I avoid EGr like the plague, not because I don't like EGR,
frankly I couldn't care less, my issue is that the SENSORS that
tell the computer the EGR is functioning correctly are notoriously
failure prone and the computer is programmed to overreact to
whatever sensor inputs it receives.

I believe that a part you don't have cannot fail and leave you
stuck alongside the road.

So it is better, long term, to take the cam sensor out but the motor will run if it is left in? What is different about the injestors? Will either fuel rail be okay?

I'm doing almost the exact swap, except putting a 92 Motor in a 94. Do the earlier engines not have a cam sensor?
