anyone know where to find a diagram of the vaccuum hose set up on a 95 wrx, car takes longer to boost as in thrashing it and only reaches 0.6bar when its redlining, been told its the vaccuum hoses which ive checked, but wondered if there are hoses i might have missed, cheers

 

Any help on the turbo/boost subject also appreciated

 

Hi Ballyscoob

Hope this helps


1. To BOV
2. To Pressure Exchange Solenoid (Over Turbo Outlet Nipple connection)
3. Fuel pressure regulator
4. Charcoal box

 

cheers for that falsk,
theres a couple of things im confused with, the hose from the boost solenoid, marked above as "air intake resonator box", i cant find anywhere to join it to? it comes out from solenoid as above but just hangs there?? Also the restrictor pill, what they for etc?

thanks again

 

No problem

Well.. "resonator box" might be the wrong word on some versions.
On my car, the "resonator box" is a cast alloy tube right after the MAF.
Ill try to see if i can find a picture.

 

You cant see it on this picture, but its the only nibble on the other side.

 

And the restrictor pill.. ive allways seen it as a design flaw, that should have been done in the Boost solenoid nibble.
It restricts the airflow

 

Hi could anyone shed some light on where to get one of the silver air pipes from.the one with the arrow on it at the bottom thank you.

 

On your wrx you should have the air filter box..then maf..then angled rubber connecting hose..then square/oval resonator box..

 

I got it with k&n induction kit home made pipe work and the standard 90° turbo inlet pipe was wanting to put the bit arrowed on as mine is a bit of a tight fit and lies quite close to the header tank just for the MAF wires as they are hitting off the tank and starting to melt a bit.put a bit black tape on to stop it as much as I could.

Cheers

 

You can get the hard pipes from eBay but try and find a decent one as there are some crap copy's about . I had a apexi one in my (might come in handy box ) ill have a look later
