Re: build evo4 or buy evo 9
so how diff can the head be from the VIII and the IX i read about it and the mivec in the IX only alters spark not valve timing, (I know what mive stands for, but this version of mivec does not involve valve timing) according to car & driver and autoweek. i don't know about the cams if they're any different.
