In Topic: GFB BOV on B4

Fooking fook, i need detailed guide with close ups on how to connect my hoses up after installing a gfb t9000 bov please, its a 2002 gtb bh5 5mt. 😓

Not sure how many pics you need. In the end this is what i did..

Light blue basically goes from Intake manifold to bov. No pills required from the factory hose you remove... I used a brass coupler so the hose doesn't bend too much. The bov will get full intake manifold pressure so it stays shut. You'll want to make sure thrle bov stays almost shut at idle. For me doenst matter as ive got a recirculate bov.

In this 2nd pic. Dark blue from fender goes directly into intake air pipe (pre turbo pipe).

Don't touch the existing red hose and pill that go down to the primary turbo.

Hope it makes sense.

Google YouTube videos of how to set the spring of a GFB vent to atmosphere bov.

Yes, do the hose 10 mod.

How are ya? Long time no see :)

Where can i get a new recirculate hose? Or does subaru charge a reasonable price for one? Haven't called them yet...

Once stock BOV is out, connect hose from the boost control solenoid directly into the intake air pipe...use the plastic coupler shown in my first pic. Don't reuse the pill.

Then intake manifold hose goes straight to the blow off valve, again, no pill to be used.

With the recirculate GFB mach 2, it doesn't flutter, at low rpm/throttle it does make a very quick, odd sounding wind noise, if you know what i mean. I think with more throttle and over ~7psi, it does make a slight hiss noise... Which is fine with me. :)
