I just recently purchased a 2003 WRX and am looking to upgrade it some. I wanted to get a better Blow off valve for it and a short throw shifter. I was was wondering if anyone out there had any suggestions? I was looking at the BPM short shifter. Any thoughts on the BPM?? As far as the blow off valve is concerned I was looking at either the Blitz DD BOV or the HKS SSQV BOV. Thoughts or suggestions??? I also was wondering if someone could tell me if I needed a BOV that routed the air back into the intake or if I could use a vent to atmosphere valve on the WRX? Thanks for your help.
