I just got this turbo thinking that it matched my manifold flange and it dosent so what flange is it? thanks in advance.

 

Looks like a T4 divided. You'll to measure it.

 

what am i measuring to see?

 

To compare it with a Garrett sized T4 flanged measurements on its website. See, some flanges that look like T4s are actually T6s. Since we can't tell that from the photos as to what it is, you must give the full measurements (remember geometry class?) of the shape of the flange.

 

Yes, that is in fact, a T4.
