You will most likely have to change at least the waterpump pulley back to stock. I installed a procharger on my friends 01 bullitt and had to swap out his factory underdrive waterpump pulley for a stock size pulley.

will i lose boost if i keep the crank pulley?

Most likely yes, I would just change back to the original pulleys...not like you're going to miss the whopping 3-4hp they gave you in n/a trim.

no is not the 3-4 hp that crank pulley I am not sure if i know how to properly install, and do i need a new crank bolt or i can reuse the old one?

depends on what pulleys you have (piggyback, steeda, march) but you most likely will need to get a stock crank pulley bolt. Local ford dealer should have them in stock...go to auto zone and rent a pulley puller, not very difficult or time consuming. Just make sure when you thread in the puller on the crank that you thread it in as far as you can get it by hand. If you only grad the first 3-4 threads you will most likely end up pulling the threads out of the crank and ruining it.

I do have a long starting bolt for that bud.
