Goosed Turbo? I Hope Not!


Recommended Posts

Hi folks

My car was running just fine until monday of this week. Now it sounds like my dump valve is just pissing air out and I have no boost? I do have boost but just not nearly what it should have, it still goes fast it just doesn't nail you into your seat like it used to. It sounds a little rough too like the exhaust may be leaking as well as the dump valve, the exhaust noise is a lot louder in the car than it used to be. So all in all it sounds like I'm loosing boost on both sides of the turbo. I haven't got a gauge (yet, one is on it's way) so I cant say for sure what the pressure is, what is it supposed to be anyway, it's a '97 JDM STi version 3?

Anyhow does this sound like my turbo is dead or could it be something a little simpler, and hopefully cheaper :banana2:

Please help :D

you could be in limp mode

i take it youve had a look at the pipe work coming from the boost solanoid yeh...

has the check engine light came on (or was it on then went out?)

check your ECU for a fault code..the might point you in the right direction (might aswell it only take 2 min)..

Circlip? Actuator? Lets 'pretend' for a minute that I'm a thicko, just where might I find these items and what should I be looking for? :rolleyes:

There is a rod that runs accross the top of your turbo from the hot side to the cold side. It connects the actuator (round thing) to your wastegate (hindged bar). There is a circlip that secures the rod. If it's come adruft you should be able to see the rod loose at one end.

Cheers, I'll go have a look, then I'll check for any fault codes. The check engine light has never come on btw. And I tried re setting the ecu on someone else' advice, it made no difference.

I cant see anything loose, there is a heatshield over the hot side of the turbo so I cant see whats going on under it, but I gave the rod a wiggle and it felt pretty secure to me? :rolleyes:
