Difference between 6.5 turbo and 6.5 non turbo

[609thomasm]

Hi all, planning on a 6.5 turbo swap into my 72 K10. Heres my question, I currently have a complete 1993 donor truck with a 6.5 turbo in it. When I bought it it ran and drove. While idling in my yard it started huffing smoke like you can't believe and pushing raw oil out the tail pipe. Now there is water in the oil also. I have not pulled it apart yet but a 6.5 non turbo motor is available to me and I am wondering if the parts are interchangeable in case I need hard parts. Thanks
