Blow off valve question

[Guest]

this is gonna sound really noob, but someone had pretty much stolen my blow off and other assorted parts but im trying to figure out are all impreza blow off's the same fitting? like could i just goto my local performance shop and just buy a generic HKS blow off valve or does it need to be specific for my model?

if specific, where would i get one for a wrx impreza gc8 1996??

cheers

Depends how and where you had it mounted but they arent specific to a car. Just buy the one you want. If it connected to your top mount intercooler youll more than likely need an adaptor to mount it on

1996 spans two different engine models, older v2 model has smaller angled intercooler, v3 has larger straight rectangular one.

they do have different blow off valves, the v2 is an inline one above the turbo

the v3 is a right angle type that sits below the i/c on the passenger side

newer models v5+ have a bov that bolts onto the i/c

you can pretty much make any aftermarket bov fit/work with some playing around, but they need to be tuned just right or your performance will suffer. try a wreckers for a 2nd hand one

can anyone tell me what type of blow off i need?? and the circle right next to the airflow has actually got 2 small pipes comming out not just one. do i need 2 or is one enough to goto the headers??

ok thats Version 2

your factory inline bov sits between the topmost red circle and where the clamped bolt is

the vacuum line to the bov comes from the middle of the manifold

the random tube sticking out in the right hand circle should be the return from the wastegate solenoid.. but you should just be able to block that off at the moment

(right hand circle) metal pipe is aftermarket.

this is the factory bov:
