With the BOV, its really not needed... The standard one is quite sufficient, and if you need a larger one later get one off a GTR
It looks to me like you like a bit of car bling, so I assume that you will eventually stretch some tyres on your rims to get some JDM offset, so look at getting 9.5" rims for the rear, and you will need the money from your BOV to cover them.
Can I ask what your previous fwd cars were?? I went from an S12 (rwd) and with standard power it took a couple of months to get a good feel with the car and its power, so take your time on the mod front unless you want another write-off on your hands. its not a race! lol
