I think we have a problem with the hot side of the turbo that we installed on a 98 LS auto. This is a DRAG III kit...has anybody heard of any problems with this set-up as far as the turbo itself is concerned. We are going to take it apart and see but it appears to be "gunked" up inside on the hot side the compressor seems to spin freely while under idle, shut the car off and the compressor wheel is very stiff.

Any thoughts

 

bearings?
