No does not require a built motor, if the car is one of the ones that does not have a bad bearing issue it should be fine. If your one of the unlucky guys any version SC will drastically increase the time before failure.
Mine for instance stock at 32k the bearings when changed were into the copper, from 32k-59k I was supercharged and on new bearings at which point they spun.
I say if your going to supercharge then have your bearings pulled/swapped. If your showing excessive wear then I would not supercharge the car even on new bearings as your just going to see the same wear just faster.
Built motor with new crank/better tolerances etc at that point would be only safe way to run it for any decent amount of time.
Trust me.. its a very bad feeling when this engine craps out on you, term 'money pit' comes to mind.
