Seeking help on turbo boost

[kurt_629]

I experienced one time that my car also unable to boost more than 0.5, I thought was the turbo actuator,
but actually required some vacuum hose routing & snap on the "tulang ikan", after that able to boost beyond 0.5bar.

definitely a lot of thoughts and time spent on my car..

some mechanic say its the turbo, advise me to change.
but if its the turbo, why can I still boost to 1 bar when I remove the air flow.

if there's a need to change, I would change..
I just got conned too many times..
I came to know the wastegate is gone, either its fake or sold to me in bad condition as half cut..
anyway, I already inform the mechanic, going to do a replacement for me..
this is the 3rd wastegate..

Kurt..check your Blow Off. If it leak it will trhrow out the air pressure required by the engine to achieve boost. Put your hand in front of it nose and pull the accelerator using your hand..if some air comes out when u open the throttle then it is already damage. The air should only comes out after the desired boost..for standard evo 3 is 0.7 bar. Let us know the finding.

if standard evo 3 is 0.7bar, that is what I am having now..

then how do you explain if I took out the air flow, I can boost till 1.0 bar?

my blow off, is standard Mitsubishi, the black boring looking type, once its throw out, the air will goes back to the engine again

My standard is 0.6, but one time my vacuum hose broke and I boost 1.1.....lol

no money to buy new car.
