well good to see you've done your research. get rid of the aftermarket bov and get a GTR one. bolts on and is an upgrade over standard. fully re circ so legal too (if they notice the difference). the actuator isnt the gtr one, use the r32 gtst. its a good mod, and again, near impossible to tell its been swapped.
post the vin, and also put up some pictures of the engine bay. to get the car legal with regard to intake, you'll have to either go back to stock airbox and get a return flow cooler (plus weld up the hole under the waser bottle which is a defect too) or go back to stock with your cooler. i'd do the former personally, as you are wanting to run more boost anyway, and make more power.
