Hello i havent seen anyone really talk about this too much in detail, i have gained some interest in these new duratec 35 motors 3.5 and 3.7 L i believe on the new mazda 6 s these power plants come with 265 and 275 stock which is like on par with a g35 motor to say the least. my question is what are the power potential? of Duratec 30's and 35's is it just worth it to get a 3.7 L and turbo it? i know you can bore out a 3.0L into a 3.2 or maybe something higher, but what power potential can we expect with our stock internals? and even so with aftermarket internals? better to swap a duratec 35 into our cars? is it possible? this will probably be a debatable thread post up!
