Hello, I am new to this website. I just picked up this 03 WRX rally blue for a good deal, I am already currently converting the interior to the STI interior.
I am more into performance but seeing as I am new to these types of engines I am unsure of my path, I used to be into DSM's now I take a big leap into the subi's.
So I was asking you all if there was a path that if you could take where you would go for the performance aspect, for instance I am unsure if the stock BOV can hold the psi from a bigger turbocharger so do I need to upgrade the BOV right away?
another question that pops into my head is what exhaust should i run i didn't want to make it a loud obnoxious roar just the conservative definitive idle that they have. possibly some type of hi-flow cat, i was looking at Megan Racing exhaust systems from the turbo back, any ideas?
another question that popped into my head was the vf34 and the vf39, i could get a new vf34 for around 900 or should i just look for a used vf39 and what is the difference between the two?
