hey, out of curiousity- what will you be tuning the setup with? is there a way to dial in/out overlap and overall cam timing via adjustable cam sprockets or something? is there some sort of electronic cam timing control on one or both of the cams on this car? i have yet to look in the factory service manual at that....
this seems to be putting the cart before the horse w/o a legit high res tuning interface, but glad to see you are working on things like this nonetheless.
my 'thin slice' thought on this whole thing is a nice truly cracked tuning interface and a different turbo flowing more efficient boost would get us what we want w/o getting involved in things such as changing cams. that's my humble 'first take'.
