idk about you guys but my 05' x hits 0-60 in 4 sec. and 0-100 in 9 sec. but all of it is stock plus i found out that my xterra has the same engine as the 350z has it in. i had some friends mess around with it and one of my friends did something to make it do that but he didnt put anything in so ill ask him what he did and ill tell ya.. by the way i hit 140 top speed.
