at the end of the day, you gotta do what makes you happy, if the OP wants to blow his wad trying to build a super crazy N/A monster Z, more power to him. There's def easier, cheaper, and more tried and true ways to do 500whp (TT or stage II s/c) but hey, I'll be the first to say if it happens, I'll be pretty excited to see it cause I think n/a builds are neato as well.
