Leave it to others to ruin your hustle. I've had the full specs on that turbo since I bought it off of Joe 2 years ago.
Garrett 60 trim journal bearing turbo. Comparable to a 70mm turbo except with a little bit larger exhaust side, .7 a/r if I remember correctly. It doesn't matter anymore, when it runs correctly in 3 years it will have already been forgotten.
