I want a car that I can do track days with.(road corse) Some auto cross and street driving. Would not be a daily driver but a few hour trips and traffic our in there too. A smaller turbo for faster spool up seams better for this? Also what type of material is the tubing. Are all the conections weilded? How about clerance to the ground? Would want to see a little over 600 at the wheels. Not all the time. Is a turbo a good aplication for this?
