as far as BOV, i dont know anything about them, so i dunno what kind to get....
i have a DSM intercooler at the moment, i was gonna put it in the space where the A/C condensor goes (since i lack A/C) but may go for the front mount eventually.
i wanted to get the blockguard and stronger rods, so i could run a boost higher than 5 or 6 PSI.
