LS3 or supercharge a e46 325i wagon?

What's happening out there I want to make my wagon a rocket ship

Anyone have any ideas of of someone in the Los Angeles area who could do this or who has and is it worth it I could just supercharge it I guess let me know what you think I know it's not cheap I don't care I have a mastiff so I need the space or I would of just got a m3, I have a 550 e60 as well so the wagon isn't my everyday car
