Mitsu 8cm vs. T3 hot side?

[bluetsi64]

I was wondering if anyone knows if a 8cm mitsu turbine housing flows better than a T3 turbine housing? The reason I ask is because I had a turbo built that is a t3/t4(garret center) with a 64 trim in a ts04 compressor housing and a .63 AR. on the hot side. and im just wondering if i should of just had the 8cm mitsu housing put on or would it even matter. Thanks Everyone

.63ar exhaust housing is a good deal bigger than an 8m housing.
