David,
Question #1:
Not an issue. The block is cast iron. Lots of weight in the front to help
the car understeer.

Question #2:
Water pumps with this year 525i (M50 motor) have a plastic impellor in the
pump. This WILL fail. If/when it fails, ensure a pump with a metal impellor
is installed. Thrust arm bushings go away and when they do, it feels like
warped rotors.

Question #3:
M50 has a timing chain. Nothing to change.
