T2 VS T3 flange

Whats the diffrence, I’ve seen a T25 before but wasn’t paying attention. What I’m trying to ask is. My friend has a nissan turbo sitting in his garage, but hes not sure what size. I just need to know if Its a t2 or a t3.

he doesn’t know what its off of?

there will be a tag in the center section, type the numbers in google and it’ll show what it is. what car its off etc etc

perfect, thanks.

would it make scene that I blew a turbo, and now the car wont start?

Usually just by looking at it you can tell a t2 vs a t3.

The exhaust flange is totally different. T3 is ALOT bigger

T3’s outside dimensions are 4.25"x2.75"
