Boost Problems

As some of you know i'm suffering from boost issues :roll:
Thought i had solved the problem by fitting a bleed valve to manually control the boost but alas no..

I'll explain the problem a little, the turbo is boosting @ 0.5bar, which i was informed could be down to the fact that when some small 2mm vacuum hoses split away from a t-piece that were linked to the actuator inlet, boost regulator and compressor outlet.
I replaced them :oops: and have since found out that the pipe coming from the compressor outlet have a restrictor built into them ( a small ball bearing apparently)

I tried a couple of the bigger breakers (Grade A and a few local ones) but i need the hose off a 97 scoob as they all have different size restrictors :!: :roll:
So after to speaking to a couple of people last night they said i could get away with fitting a bleed valve and eliminate the t-piece and not hve to get this pipe.
I fitted the bleed valve this afternoon and still no luck, now the bleed valve is a 3 way :roll: but i was told to leave the boost regulator pipe off as i didnt require this.

I have tried resetting the ecu as well in case it had become accustomed to running 0.5bar however it still doesnt seem to be running any better, it seems to be a little more responsive but its not hitting nowhere near the boost it used to :(

Can someone help before the BP drag night, as Jayne is getting a little p*ssy that i keep nailing her car harder than mine :lol:

Andy, I tried to get one during the week at Mocom Racing but he had run out as Essex Subaru Breakers has been requiring all of his.

He did say about gettign a bundle of them in.

Have you tried the main Subaru stealer?

that was going to be last resort as no doubt they would have to order them in as they arent in stock so id have to wait for months or something :lol:
