T4 vs T5 flanges

[gnxtc2]

What's the difference between a T4 flange and T5 flange? Also Now there is a T6 flange. Then there is a tangetial (sp?) or divided.

Which flows the most? And what are the inlet sizes?

I know they're 4 bolt flanges

Thanks

Most people refer to the T6 flange as the T5 flange, The T6 is the thumper size flange like the 91mm to 106mm used. Now some of the GT series turbos for the buicks use the T6 flange like the GT47. The T6 is larger than the T4. Then you get into the tang housings, on center housings and divided housings. Are you interested in a certain turbo and need to choose a housing?
