Great choice. Yeah, for me 500whp will be plenty, so the 7163 will fit the bill awesomely. I feel like the chassis will be overwhelmed beyond that point becuz FWD. Bigger turbos make more sense to me on the MS6 because of the extra weight and AWD.Full Race kit doesn't work with the 7670 it is the next step up in frame size. Having custom top mount mani made by 16W fabworks. 7163 is a great turbo just not quite big enough for me. This will flow equal or a little more then a GTX35 but spool a lot quicker. Not 7163 quick but you can't have it all.
