97 obs 7.3 psd. When I inspected my turbo it was tight, spins freely but had a sort of sandblast look to the verticle edges of each blade, not the whole blade just the edges. Anything to worry about? Also I can`t hear the turbo at all. Shouldn`t I be able to hear it at least a little bit after I just did a Tymar intake mod. and ccv mod. and bb mod. today. The rest is stock. Next week I get a 3" downpipe (I`m told you can`t put a 4" dp on the 97 obs) 4" exaust 5" rolled tip w/ cat and muff delete. I`m told I will def. get the turbo whistling then but I`m not sure. All opinions will be appreciated.
