No boost ????

[nestamon99]

Hi guys and gals...I am new to DSMs and I need your help and this club. I bought an eagle talon tsi awd for real cheap. I couldn't pass the opportunity. When I drove the vehicle for the first time, the turbo worked. Then about 30 miles later my fun was taken away from me. The turbo decided to stop spooling. I figured my turbo was bad, so I check the shaft play and there's none. It's very surprising because this car has 200k miles. The guy who I bought it from didn't know much about the vehicle. I do know he replaced the knock sensor with a used one. I don't think it would stop the turbo from spooling though!!??? I can hear the turbo whining up but no boost. So I checked my wastegate and thinking that it was bad, I replaced it with one my brother had laying around from another eagle talon. Nothing. I checked vaccuum from every hose connected to the wastegate. I even pulled on the rod of the wastegate and used my thumb to block all the air it sucked in. Then I moved my finger from the nipple on the wastegate and air was released. So I know the nipple is not clogged. I installed washers between the turbo and the wastegate bracket to close the wastegate shut. Nothing, no boost. Then I checked the blow off valve to see if it was not working and maybe leaking all that air. Nope. No air coming out while the engine is revving. So, I replaced the MAS with my brothers. I know this one is working but nothing. No BOOST still. Seeing my brother's car and riding in it with lots of boost makes me really mad. Need some input guys.

What does the car do when you go into WOT(wide open throttle)?

Something is hugly leaking or not hooked up right.

If the car bucks, and sputters, with little or no boost, you might have holes in your Intercooler outlet or inlet(it happens to every stock car I have ever seen).

at WOT the car doesn't sputter, jolt, or surge. It feels really gutless and specially on uphills. There's also a crack on the exhaust manifold but I don't think is the cause of the
problem. I even installed a manual boost controller and it will not boost up at all. I have tried to listen for any whistleling noises or anything that would indicate a vaccuum leak or air leak. I will have to wait 'til next weekend to work on the car.
