So I was thinking about buying a used 103, stripping it down and rebuilding it for a straight swap. I heard that Brabus did a 3.6L M103? How did they do this?

What sort of power could I get out of refreshing the bottom end with different components?

Would the K-Jet system need modifications or would it be literally just a block swap? What about the difference between the 722.3 and 722.4 when it comes to handling HP? Are they both equally able?

Thanks!
