To get Antti A's estimate out of a 617 what needs to be done besides a Myna pump, intercooler, and VNT? Are we talking custom connecting rods, head work (don't know what could really be done with the limited space), stronger fasteners, custom crank, custom cam?
My wants are less ambitious than 380hp but it would be nice to know what needs to be done besides the standard formula.
