Thanks for everyone's responses/info. Very helpful. I'm only new to the whole "Car Enthusiast" thing so I'm learning as I go. I recently purchased an R33 (all stock standard) and that was the beginning of a whole new passion. In response to the quote, the only reason that I'm not sure how far I'd like to go, is that have no idea how far I can go. So my plan evolves as my knowledge increases. I'm not the type of person to do things in half measures so if I'm gonna do it, I'm gonna do it right. So I don't mind spending money on quality. I presume that I'll be modifying more as time goes on, so I figure I need to do things that allow for further upgrades.
