i didn't T off the PCV valve after all. i T'd off the charcoal fuel/emission filter cause it was gonna be much easier then the PCV. i did it with a plastic T editplatic T painted flat black) instead of the bulky brass homedepot T <-what was i thinking .
close up:
further away so you could see where i Td' off.

hardly no boost spikes at all with an internal w/g. only a 1 psi boost spike on 2nd & 3rd gear. now that the waste gate isn't feeding off the fuel pressure regulator, and the BOV vacuum source, the BOV doesn't flutter on low psi (5-7psi) and the BOV sounds louder too. but the main purpose as why i did this is to avaoid buying a $40. vacuum manifold and to end of reduce the almost 3psi in boost spikes i was getting. i already drove the car for a while and it worked out good.

you guys don't have Princess Auto in the states? you can get those vacuum manifolds from their hydraulics section for $5-$10 depending on the size & number of 'ports'. and they look just like the $50 ones...

why not just use the nipple on the compressor side of the turbo for the WG and the FPR for the BOV?

b/c you loose boost that way due to the pressure drop from the air having to travel through the ic and charge pipes.
