You can see the benefit of a low mount twin scroll (vs. to mount open turbine housing) if you were spooling the same with your T3 .82 a/r (equivalent turbine). In theory that turbine should have spool a good bit faster compared to a T4 1.0 a/r twin scroll, since it is much smaller.
Here is another example...also twin scroll but with the larger 67mm turbo. This was a 6766 1.0 a/t twin scroll on a 350z (so even less displacement to drive the turbine):

You can see by the torque, that with some aggressive timing it was spooled at 3500rpm (to 9psi spring pressure). For DJ conversion add 13% to the final numbers.
