Is my turbo shot or the wastegate?
Ok heres my problem, I have be having trouble see no boost on the gauge. so I take the line off the wastegate. The line is still on the turbo, while the car is running, I feel slight to no air coming out, so rev it pretty good. I feel air coming out but its not strong. The runs the same with or without that line hooked up, (I didn't drive the car on the street like this) so than I move the flaper on the exhust side and theres no difference, so I disconnect wastegate arm to the flapper still no difference on boost presure or the way the car runs, so is the turbo shot or the waste gate? can anybody help me out?

Re:Is my turbo shot or the wastegate?
Thats a tough one to figure out. You have a leak somewhere wheather it's vacuum or a charge pipe leak I'm not sure. I wouldn't drive it on the street without the wastegate being hooked up though. Without the wastegate you could over boost the motor... But, you did say your not getting any boost, so I would say theres a problem with the charge pipes. Check em' out and see what you find. Make sure all your vacuum lines are hooked up correctly also.

Re:Is my turbo shot or the wastegate?
yea I drove the car, it does fell like it pulls, you can hear the turbo spool, I checked the charge pipes for leaks, I capped the turbo off and blew 40psi air threw the pipes with a compressor,than I put soap/water around the pipes. and the only leaks that I seen were from around the turbo. But I never checked to see if the intercooler leaks, when I bought it, it was pressure tested for 30 psi, but than I had other pipes welded on it, But the guy who welded it is a good welder and filled the intercoller up with water to keep it cool.where should I hook my boost gauge? I have it hooked after the TB. The boost gauges reads -20 than when I get on it it goes to 0.

I've heard the Fuel pressure regulator vacuum line is a good spot to tap into for boost guages etc. Yeah, it doesn't sound like the turbo is the problem. Turbo's will spool basically until they die. And you'll know it when it dies!!! I don't know man, it just sounds like a bosst or vacuum leak to me. If you figure it out let me know what it was.

ok I tapped the Fuel pressure regulator line, and other places on the manifold, and I still had the same problem, -20 vaccum and when I rev it, it only goes back up 0. and Iam pretty sure I have no leaks on the pipes. Iam going to check all the pipes again, and I have a auto meter boost gauge. and its brand new, But I wonder if its a faulty gauge? damm you car

I would drive the car and test new spots while driving, but I have to get the car inspected, and the last the time I had the car on the street the cops seen I had no inspec, and were out to get me. so I have to wait till wednesday to have it on the street. thanks for the info
Or you could do it the sneaky way and do it Night Rider style. Try it at night somewhere you won't get caught.
