I knew the cams wouldn't work with a turbo but if I do decide to go turbo I am going to go balls out and get the cams too so switching them would not be a problem. And I was hoping that by the time I can afford the heads the unichip for a GC8 will be out or I can afford a TEC-II (maybe one will come up in the classifieds of price drop for TEC-II when TEC-III comes out) or Haltech. Since the spicy cams peak at redline can't you still run them just shifting at redline. Are there any power differences other that RPM range?
