Yes!! xactly. turbine is pretty much the same in both the turbo. only the hosusing is different as the HKS one is designed for External Wastegate and the other on has a port for interwastegate. fan size is the same. the complte specs are.

GT3040 Turbo





HKS GT3040 - 500 PS Output

COMPRESSOR:
-Wheel- 50 Trim - 58.0 Inducer / 82.0 Major
-Housing- 100 Inlet / 60 Outlet - 0.60 A/R

-Housing- GT25 inlet / External GT30 outlet; 0.61, 0.73, 0.87, 1.01, 1.12 A/R

.82 turbine on the h22, definitely.
on the b16, anything lower than .82 will be best imo.
