Dudes I'm sorry to say but I'm very confused everyone i seem to talk to about this mod on a turbo engine seems to think its not worth it? why is this so? intake flow is everything for a n/a and turbo car right? or am i missing something? i have read various articles on the web and they say to build a good turbo motor start by building a great n/a motor. is it the fact that u cannot fit much larger valves? because i have been looking and it seems you can fit a good 20% bigger valve there? sorry for so many questions I'm just so confuzzeled Andrew
