what to do with my BOV and how to install it

I need some help on how to install a BOV, i have a flange with it but i have a choice of ordering a 3piece greddy hard pipe kit(intake elbow; S pipe; compresser pipe) and cut a hole in it and weld it onto that or should i cut a hole in the stock piping, also after all that which vacume hose should i T off of and do i still us my stock pressure reliese valve...

easiest way, put it in the stock position and run the hoses EXACTLY as they were before.
doesn't need to be rocket science and you only need to change the positioning if you are really concerned about boost characteristics (i.e. faster release of pressure at the throttle butterflies).

What you are showing is the flange used so you can attach it directly to the hose that you removed the stock one from.

That flange in the pick would not work for welding into the hard pipes. It is meant to use the stock hose in the stock position.....( Or you could use longer hose and relocate it but there is NO need to do that)

As for the valve that vents the secondary boost until transition. ( The one coming from the rear turbo area) Yes you need to keep that unless you are going to run non-sequential.
