Actually I have considered all of that but didnt think it would be really relevant to start posting about suspension, chassis, bakes etc etc in a engine thread....but yes all that has been considered and planned for already. Information im hunting down now is more about the wiring then anything.
Also just because I want the car to have 500whp doesnt mean ill be running around everyday at 500whp I ust want that potential to be there if I call on it...same reason I choose the 2J. If one day I want to go more power I can or less for that matter with minimum amount of modification. Also is my reasoning behind going for the larger higher spooling turbos, I would like one that begins spooling hard about mid rpm band so that there is less chance of losing control on public roads unless I mean to get into boost. Since on the road course etc you are usually high in the rpm band through most of the gears there will be little need for a really fast spooling turbo in my opinion.
