look the fact of the matter is that an r34 is a great car because there aren't many of them here... the z06 is fast and cheaper true. However, the Infiniti R35 Skyline GTR is gonna kick the z06's ass. 3.5VQ with twin turbo, AWD, Brembo breaks, TWIN TURBO.... did i mention a twin turbo'd 3.5v6 which is already in the g35/350z with 300hp?
