Either way, the good information is that there are several exhaust manifolds and bolt patterns in the N62 family and they sometimes require drilling and tapping if you mix and match.
I was expecting only one side to be different between the e70 X5 and the engines I looked at from an E65 750i. Which is also different than the 4.8is. It probably all just comes down to how the exhaust manifolds fit best.
Did you happen to look into swapping an N62B48 engine for the extra 40hp/40ft*lbs instead of putting another 4.4l engine in? Would it take more than just changing the control module?

As I mentioned in my previous post the 4.4i manifolds between the cars & trucks are not the same. In fact, the bolt patterns are completely opposite between the 745 & the X5 4.4i N62.
In regards to the 4.8, I’d have also swapped if one were to be going through all this trouble. Transmission (torque converter) is also a different unit.
