E70 X5M Engine Swap S63B44 sway to S63B44TXX
 

Hi,
Just purchased an X5M with rod knock - looking for some advise on if the current S63 Engine can be swapped with an updated S63 engine ( S63B44T0, S63B44T2 or S63B44T4)

Can I update the engine to one of the other S63 engine with updated technicals?

How difficult and what is involved.
Alternatively if it is too involve I may need to just rebuild this S63B44

Thanks

Hi Motorsport, I am also currently in the process of negotiating/purchasing a 2010 BMW X5M with188,000km/116,817miles for $5000 with a poorly running engine (Starts and runs but misfires on Cylinder 5 & 6). Doesn’t sound like rod knock but is making a strange “popping” noise around cylinder 5&6.

It was scanned/diagnosed by the local BMW dealership as needing a replacement engine (used scan tool & bore scope). Owner was quoted $51,000..!!

I am considering purchasing a used or rebuilt BMW S63 engine…but they are both expensive!
I realize they are extremely high performance but $10000-$15000 for a used engine seems crazy…? I still want to own & drive an X5M but maybe I should either find one with very low miles or a newer F15 model with less issues?

Did you decide to go with a S63 TU for an engine replacement?
