Whining turbo w/ no boost

[bunkaking16]

i have a 96 gst and i was drivin tonight just normal wasnt runnin it hard at all and i stop at a stop light and when i turn the corner and get on the gas all i hear is this whining like a supercharger and it scared the crap out of me so i got off the gas real quick and then on my way home it just whined everytime i would accelerate and i had no boost at all. so i'm pretty sure my turbo went but i just want to make sure and hear from everyone what they think. also on the way home i would give it a lil more gas when it was whining and the whining would get quieter and just sounded like metal on metal scraping. so just let me know what you think. im pretty sure its the turbo. and im pissed

Yep sounds like it. Pull the intake off and check for shaft play and if its bad enough than you probly have metal in the oil. So that will need flushed out a few times. You may need to clean out all your intercooler hoses, cause the metal grinding off goes into the intake and when mine went, it left metal inbeded in the rubber hoses.

check for boost leaks, it could possibly be a popped coupler

Or use this to put the 14b on your car as the 14b 16g (all 16g) 18g and 20g turbos all have the same bolt pattern and fit no problems, then you just need supporting mods. Then when you get the money to go bigger do a 14b-16g-20g.

Nice to see another local dsm'er. Make sure the turbo has no side to side play at all.

Turbos can have some sideplay :O it's endplay that you don't want but we knew that's what you meant jay Of course from what your describing in the symptoms you're going to have excessive side play that allows the inducer wheel to come into contact with the compressor housing.

Last time this happened to me, I popped my intake off and I could move the shaft around like a joystick
