M52b20 swap to m52b28tu

Hey folks,

I'm considering replacing my engine to a m52b28. I've heard it is a straight drop, and the same ecu can be reflashed for the 2.8. Can someone confirm this?

Also does the m52b28tu run 2 post o2 sensors or one? Don't want to spend too much time modifying wiring harnesses etc..

Opinions/criticism? Welcome..
