idk i think a v6 wouldnt be as cool as many of you do. i think the car was meant to be something else, the most powerful na 4 cylinder shoud be topped by something better not bigger. the ap1 s2k had the most output per liter than any production car NA. i think they should top that...v6 would be cool but if it produced more than 120 hp per litre. otheriwse no.
