the car is runnin no boost!! need help!!

[crazyfast]

my car was running fine.. I haven't drive the car for 2 days... then I start the car.. idling is fine.. when engine gets warm.. then I drive it.... but rpm goes up very slow and engine feels powerless.. and when I look at the boost gauge.. it won't pass -0.5kg... even I rev it to 5000rpm.... still no boost.I checked spark plug gap... they r gap at .28.. still run like ****I checked all intake piping... seems no air leaksI checked wastegate... it moves..

what could be the problem??? ><can anyone help me plz!!!!

you better stop boosting for the time being

maybe your turbo seized? should it be seized, I have a t25 for sale if you're interested, it has 38k miles on it and it has absolutely no shaft play but with lots of play. That's right, I can't not even move it for 0.5mm, it does not move but spins freely.

I took out the intake pipe and spin the compress wheel and it sping freely... but my friend told me my turbo is gone... anyone can help?

lol, just because you are not boosting doesn't mean your turbo is gone. Does your friend see shaft play on the turbo?

i know you checked all hoses, try to rev it a little while in front of the car with engine bay open and maybe you can hear the leak somewhere

shaft play means the center shaft that holds compressor wheels moves a little bit?? if so... my turbo doesn't do dat... sping pretty good!!when I open the hood... it's too noise.. can't really hear anything ^^"can it be the spark plugs? I heard someone saying he can't not boost.. and bought a set of NGK BKR6 ES-11 plugs... gap at .28... then problem sloved... what do you think??

turbo dont boost at rev at netural it only have boost at gears + gas. if gears + gas = no boost check to see if theres any leaks in pipes, vacum lines is properly clamp, and etc. hope that helps.
