the ssqv is the best bov on the market. it is a pull type valve, so it can't leak at all. the blitz timers have a separate display/control panel so they can be mounted virtually anywhere. the hks timers can be cheaper, i bought my type 0 today for $80 (still waiting on shipping). boost controlers, both companys make nice ones. HKS EVC, thats super tyte. and the SBC-ID V2 + PM-ID V2 combo from Blitz is godlike. if you are just looking for the boost controler without the power meter, thats cool too. the boost controler is the SBC-ID V2.
