I have been trying to get help for this problem for sometime and have not had any luck finding out whats wrong. I posted another thread and still no luck. Well, I can be leaving the driveway the car will shift out into 2nd gear and then I get a loud winding noise and boost doesn't seem to go over 5lbs on factory boost gauge and rpm's are across the board but after market tach reads ok, it seems like something is in a bind. I'm not sure where its coming from but sounds as if it could be coming from the turbo, so I sent it to Limit Engineering and had it rebuilt. I got it back, bolted it back on but still had the same results. So back to the drawing board, took it out for a test drive, pulling out the drive, car change into 2nd and start winding. I give it a little more accelleration it gets louder and car doesn't really seem to gain any speed. Pull back into the yard and popped the hood at idle the car seems alright and rev the rpm's way up and you here the winding noise but only when you rev it way up. It seems as if its still coming from the turbo but also could be the intercooler or filter. Could this possibly could be a blown head gasket or wiped cam? But also the cam is only about 7 months old and a few hundred miles but then again who knows. So please give some answers.
