Converting is relatively simple. First, you have to relocate the MAF sensor so that is exists between the I/C and TB. Second, use any kind of BOV and vent to atmosphere.
At some point, get it tuned to properly handle the different configuration.
Your blower is 'preconfigured' in a draw-through setup, where as air is blown off through the cheapy Bosch, it get re-routed back to the intake in front of the blower, thereby keeping all the air in the closed system. The MAF sensor is before the blower, near the air filter, and any air that passes by it is assumed to be going into the engine, hence the recirculating BPV is needed.
In a blow-through, with the MAF located closer to the throttle body, you can do whatever you want ahead of it, including blowing out air passed through the BPV. Remember, once air gets compressed, it gets hotter. And recirculating that back through the blower is like feeding it hot air. When you blow that off to atmosphere, you keep that already-heated air out of the system, thereby improving the cooling efficiency of the intercooler, and lower intake air temps.
Search and read up on blow-through and draw-through setups. Yes, it is worth the effort to do it blow-through, IMO.
