SO, it is a T6 frame turbo? That ,makes a big difference.

No it's a T4 still. The diffrence is the Turbonetics turbine had a 76mm wheel and the Garret has a 87mm wheel. The nozzle area look really opened up in the Garret. The Turbonetics had a 3" down pipe vs 4" on the Garret.
We shared our data log from all the runs. The engineer recommended this turbo to us.
BTW- This guy does a ton of Toyota 2jz and fz stuff.
