Hi guys, i did a little search but im not entirely sure. My mate has an old T3 turbo and I was just trying to find if different T3s have different specs or are all t3s the same? It came of a european saab 9000 2.0ltr Turbo.

 

most if not all t3's are different, the t3 name come from the inlet flange of the turbo, i have a volvo turbo that is a t3. it has different ar. than your turbo but the bolt patteern/ flange is the same.
