I,ve lost power completely from the twin turbos on my 94 Legacy GT. My boost guage doesn't even register + figure. I have checked all the pipe work and connections and this all appears to be fine. When the engine is revved there is a wheeze noise like an ashmatic instead of a flutter (which I used to get) It has an induction filter fitted that is the only difference to the car being stock. I was having problems with the car previously often throwing up a error code 66 but it was tempermental like something was sticking shut not allowing pressure through

Please help asap

take the inlet pipes of and check the turbos are not siezed

had that on a diesel once tickover was fine wouldnt rev though

 

I would also check the wheels to make sure they are not seized, chances of both seizing are slim though.
I would say check the inlet pipe again (to the throttle body or CC), it sounds like it may have a split in it due to the sound and loss of boost.
Are you getting any positive boost at all on your gauge, even .1bar?

Not even .1 bar. How do I check turbo pull off inlet pipe then what?

remove inlte pipe from the front of the turbo and check that the wheel inside spins freely, you should be able to spin it with your fingers then let go and it should spin for a couple of secs.
If you are not seeing any positive boost then i would say that the compressors are stuck.
