Edit: Sorry. I basically just repeated everything Jeep2Montero said.

Gen III's have a 3.5 or a 3.8 from 2003 to 2006. Gen III's are also drive by wire throttle. No throttle cable.

Don't know if that matters or not.

I would think all of the sensors we need to be swapped and possibly intake manifolds/ exhaust manifolds/ EGR system from the Gen II truck to the Gen III engine.

If you are talking about a 2001 Montero Sport Limited, I believe they still used the 6G72.
