cant find the dimensions on any diagrams

heres a bad diagram i made of the flange

 

Where did you find these dimensions? Those don't seem to match anything common. Is this what you measured on a turbo?

 

Post a pic of the actual flange showing the mount holes center to center measurement with whatever you are using to measure it. Garrett T4 is 82.55mm x 69.5mm and T6 is 112.78mm x 69.85mm. Holset T5 flange is 88.9mm x 70mm. Greddy dual inlet TD07S, T78, T88 is 82.5mm x 70mm.

dual port (dual scroll is often misused too) exhaust inlet flange is what it is called.

 

heres a picture

 

Most likely a Borg Warner T6 flange. Are there any other markings on the housing other than the internal AR 1.34?

 

measurements of this please is milimeters. hard to tell from the photo alone
