Pre face lift stock boost

[disco-ian]

Iv still done nothing into finding out what my problem is as the weather is so **** outside. But have all the suggestions from this thread to go on when I do pull my fingure out. Also in the process of buying I compressor :-)

could the wastegate springs be tired? or a potential mix up and somehow they ran incorrect boost from the factory?

haha, i got a little confused, couldnt see any rory posting on this thread lol, sometimes it is a really good thing to be wrong, pulled off the red tipped pipe off the intake elbow, blocked off hole, took it out, got over 15psi, very pleased, left it off as i had go to someones house, just tried to boost below about 10psi, hit fuel cut a couple times at about 12 psi, pipes back on now though, car felt very quick at 10psi, need to figure out why itl only get about 6 normally

It is a good test to do, just to give you a bit of confidence that the turbos are ok.
If it is a stock boost setup then you are correct the boost control pipework could plumed in wrong, or the factory boost solenoid valve could be faulty.
Have a look at the jap workshop manual in the library, section intake/exhaust and there is a good diagram in there that shows you how it is supposed to be corrected up.

Right well just bought a fox 50 litre compressor so waiting for it to turn up.

Dava I cant find the thread you did on boost leak. I did a search but loads of stuff comes up

Dont suppose you have it in your profile somewhere do you

Just had a thought.

If I pull the actuator pipes and block off and it runs say 1 bar surely that is as good as a boost leak.

So if that works it must be the controll solenoid???

Not really, all the uncontrolled boost test does is shows you the turbos can produce more boost than your current boost control allows.

Just looked at this thread again
Here is the link to the kit you need.

Hi Dave,
Tanks for the link mate. Had already found your post on that though. Thats what lead me to find the injector seal were leaking. I have new injector seals now (all thre per injector) and will be replacing them soon

I think I might have a lazy gauge so will be testing that on my regulator from the compressor soon and might buy another one as a spare.

boost leak tester are great, you just have to remeber to spary every seal, i just use a strong solution of washing up liquid and water in a spray bottle, works atreat.
don't forget about the sparying the intercooler pipes and BOV for leaks.
i tend to work from turbo Y pipe entry point through intercooler and pipe work up to the throttle body and pipes coming off that, vacuum tank boost solenoud fuel pressure solenoid, power steering vac lines, etc), plunum chamber (pipe coming off that), inlet manifold, every connection, right up to the injector seals at the end.
tends to clean the engine bay up a bit as well.
