Ok, so I have finally decided to turbo my R... Most likely I am going to go with a Drag III Turbo kit, unless there are better ones. In order to run as safe as possible (engine wise), what other mods and parts am I going to have to do/buy? Pistons? FPR? etc.... Any help would be great. Also, what is the average boost people are running on their Rs? My goal is anywhere in the 12s... (preferably on street tires.)

Thanks for all the help in advance. (PLEASE NO FLAMES ON TURBO)
