in need of serious help!!!

[Mazdamarine1723]

this is the deal, my car was fine one day then the next it wasnt, i was getting no boost at all and my turbo was making a weird whining noise, so i took the turbo out and replaced the exhaust manifold gasket, exhaust flange gasket and my downpipe gasketand bolted everything back on nice and tight but when i turned it on to see if the problem was fixed the car turned on nicely and normal and had a perfect idle and no heating problems the car was fine EXCEPT!! i was getting no boost!!! it sounds like the turbo is boosting and wants to through the boost into my engine but somthing is restricting it or somthing. im awnserless and confused, any help or suddestions and i desperatley need my car ASAP!!! thanks everyone i appreciate it!!!

my only suggestion would be possibly you turbo crapped out. There has been a thing where the turbo would get oil caked in it and crap out. Im assuming your warranty expired?

Maybe your BOV/BPV or wastegate flap is stuck open.
Check them out.

do you have the stock plastic pipes or hard pipes? if its the plastic pipes check the pipe that comes off the turbo and into the side mount intercooler. or check the line to your wastegate actuator........what does your boost/vacuum gauge read when your in vacuum? should be between 20-25

you gotta be more specific... what exactly does the car do when you try to go?

I would check all of your pipes and lines.

If all seems normal, pressure test the pipes and IC.

FYI to test if youe wastegate Actuator is busted.....trace the vacuum line to where the Wastegate Actuator connects to a vacuum source, take it off and blow into it. If you can blow through the diaphram inside is tirn and you need a new wastegate actuator if you can't blow through then its still good.
