Yes.. the 2.4 liter configuration will work as the same power plant is in both models. The issue will be the transmission mounting surface on the 4x4 vs the 2x4. You need to insure that the main seal area has same pattern and bolt pattern. YOu will also need to be conscious that the motor you are getting the 2x4 has been broken in on 2 wheel drive and a 4 wheel puts more torque and strain on engine.... so be sure once placed you give a good slow break in process or you could crack the block or crank shaft

You don't provide much information to go on (type of vehicle, type of engine, 2wd or 4wd, etc.) RPM is always going to be based on the speed you're traveling with a standard transmission. My 4 cyl 5 speed Nissan pickup in 5th gear runs at 3000 RPM at about 75mph.

that is a normal rpm for the nissan pickup (hardbody)
