Nothing. It's just unnecessary for this application and slightly reduces efficiency. Sounds neat though.
See the FAQ for transmission swapping info.
The TII transmission bolts on but requires the complete TII drivetrain (see FAQ).
There's nothing really you can do to the NA transmission which is a worthwhile upgrade. All upgrades will cost much more then just going to a TII transmission.
2nd Gen RX-7s have 4 injectors; two primary, two secondary. Below about 3800 RPM and 2" of vacuum, it operates on the primary injectors only. When engine speed is higher then 3800RPM and less vacuum is being drawn then 2" (WOT, boost, etc.) then the primaries are ramped down a bit and the secondaries are bought in. The car is no being fuelled by 4 injectors. As fuel requirements increase, all injectors ramp up.
With a small and fast spooling turbo, you will want to bring in the secondaries sooner.

Certainly. But you need to also install:
-TII flywheel, clutch, pressure plate
-TII slave cylinder
-TII starter
-TII driveshaft, differential, axels
-Adapt the wiring.
So the turbo clutch and pressure plate, and driveshaft, can i buy an aftermarket LSD?

I keep hearing it's better to just get a TII and swap...
What problems would I encounter if did everything necessary on the NA engine
Aluminum flywheel, upgrade clutch and pressure plate, new manifolds, Rear end, wastegate, ECU, Apex Seals, FMI, Turbo Timer, Boost Controller, Axles and so on?

TQ is irrelevant it will also always be less then HP above 5252 anyways.
