Hello.I am new to this form.I am new to sti's also.All I have on my sti is a intake.What blow off valve should I get for my daily driver?Also should I need any computer programing or tunning for these mods?How far can I mod a sti till it needs fuel system upgrades and computer tunning?
So many questions.I have a chevy s10 that runs 10.50's and I just want to learn something different.So I got a sti.

 

No need for a aftermarket BOV at this point in your STi's life. The stock one should be able to handle whatever boost your making right now. If you upgrade your turbo i.e (sr50 or gt-30r) you might consider it actually you'll more then likely need to at that point. At this point your STi's Stock BOV can handel pretty much so whatever you could possible do to the VF39 Turbo that comes in your ride. Some mod it just for the sound, but performance gains are next to nothing. If your looking for more power out of you car try a Turbo Back Exaust (TBE) and have your turbo ported. Engine Management is always a plus and is almost vital to your cars upgrades. For EM i would recommend EcuTek or UTEC as possible options.

 

WOW.Thanks.That pretty much answered all my questions.Thanks.

 

Can I adjust my stock blow off valve?

 

Nope, its non adjustable. If you did want to get one, at least get one that has Recirculatory possibilities, it seems our ecu's dont like when you vent 100% to atmosphere. GFB makes a nice BOV that i know people run with stock turbos and only mild upgrades.
