Hey all,
So, what motor differences exist between the B58 in the G05 X40i and the X3 M40i? What components of the X3 M40i engine are different, hardened etc. vs the motor in the X5 40i. As you are aware, the X3 M40i I6 motor has, what, 50 extra HP vs the larger and heavier X5 (which makes no sense to me), so, when we start adding boost to the X5 40i variant of the motor are we at risk because we have less capable components in the motor (or fuel pumps / injectors).
Thanks!
