I have a few questions about this swap. My current motor is a factory stock b20z2(01) that i am replacing with a jdm b20b8 (00). I understand that the crank sensor is a item that i can remove from my motor and install onto the b20b8....are there any other things i need to be aware of that will require keeping from my existing motor. Someone said the intakes needed to be swapped....anyone know why....different wiring on intakes? Anything else? These motors look like carbon copies of one another including intakes..knock sensor...etc.

help would be appreciated
