Yeah you often forget that sometimes Jim; you think how much faster Skylines are than an impreza say, but the block is 1/3 bigger (assuming there's no shneaky stroker/overbore kits used) It's also another reason you see some of the american scoobies running 9's and such, because they're using aftermarket FI kits on the 2.5NA block and wondering why british scoobies have trouble getting near those times.
