when i bought my car a while back the guy said it was an upgraded stock turbo? wtf is that? it has no shaft play no wiggle room but after the inlet bell it seems the turbo was bored or someone tried porting on inlet side? i know its a stock housing says garret upside down other than that i have the tin man cold air.... and to be quite honest it sounds more like a whipple supercharger than a turbo? it sounds like its whinding up when going into boost.. it boost very quickly no smoke no problems..someone just asked me earlier today if i had a supercharger in it?..my friends are messing with me saying its a svt buick lol..also my brother also has a tin man cold air but he has a bigger turbo and his doesnt whine it sucks as it spools? so the question is..is that normal or is it just the echo of the tin man ? and is there such thing as porting a stock turbo (inlet)
