That time in 2003-2004 the engine was way different
Furthermore they do NOT "drill" V10 engine of M5,
Then how they can increase displacement ?
from 545i to 5.2!!! it needs a lot of work.
They put the engine into a kind of device and it do the work in 2 hrs .
But you should talk to people who made that and they got a new car. (that time 550i was not available as it is only for one year out...) that explains all. 
pace.
pace.
.550i isn't faster of 545i ... Simply it has a worse consumption
.The same is for 545i @5.2 ... If you really want to increase 545i power, you need a supercharger or a turbocharger .
