ok i get it...lets say you buy a used less powerfull Sti and put 25k into it...so lets say you get all the bolt on's, intake, exhaust, headers, cams, pulleys, short shifter, clutch, injectors, bigger turbo, chip, nitrous, and some internal work...port/polish the motor...thats about 25k considering the sti's come with descent parts so upgrading them are expensive. so after all this, the ferrari would still blow the doors off of it....then if you wanted to dump the 80-100k into it like you said you could do a lot more, but you would be rebuilding the motor every time it runs down the track...im really not trying to argue with you slojo...for real man, im not even a supercar fan, but i do respect them greatly....i'll just keep driving my 240
