get the Dub... i've owned both cars and Ford = crap... for what it would take to make the SVT faster then the 1.8t you could of just bought and Audi/BMW... buy the 1.8t add GIAC X+ and you will not even remember thinking about buying a SVT. If you we had Cosworth Focus or euro turbo models i would say buy that but we don't.
end of story.
ps. my stock turbo 1.8t made 225whp/290lbs and did 13's in the 1/4
