yea i was wondering if anyone can help me out i have a 97 gst and car is going on its 3rd turbo and it keeps going out the same way starts off boostin fine and last all about 5-10 min then makes a loud winding noise and stops boosting cant figure out what is wrong..

 

Sounds like an oil feed problem which would starve the shaft of oil and seize the turbo.

 

thats the only thing that i have not checked on it... when i got the car the feed line was hooked up to the a spot where the oil pressure sending unit goes at and i have left it there since should i change it and run it from somewhere diff.

 

off the head.... take the oil line off start the car and turn it off quick and i mean QUICK !!! lol if theres oil all over the place then thats not ur problem

 

if i get oil pressure.. then what else can it be..

 

Possibly a clogged oil feed line.

 

i could also be a clogged oil return line. They aren't too expensive.

 

any one have a cheap stock turbo cause im not going to spend alot of money buying another good turbo so this same crap happen again.. ill be going on turbo #5 if it doesnt work its up for sale

 

you are running the turbos without oil pressure.
you can only blame yourself for not using new oil feed line.
in the case of t25 that line is nothing but standard brake line available at discount for about 5$.

 

aight thanx people... im going to change the line again and try with another turbo hopefully things run fine... other wise up for sale... im running out of patience with the car..
