Are S4 and S5 Turbine Wheels Interchangable?

Wanting to know if I can put a S4 Turbine Wheel and Shaft in a S5 Turbine Housing and center section?

Yes.

Turbos are identical:
compressor wheel
compressor housing
turbine wheel
center housing
Basically, the entire CHRA is the same.

NOT the same:
turbine housing
oil drain pipe

Ok Ted, thanks. I figured you would have the answer :) I just bought eriksseven's old TO4B Hybrid and the shop doing the balancing told me the compressor wheel and shaft were damaged and he is unable to balance :( ........ So I guess I will need another compressor wheel and maybe I can reuse my stock S4 shaft and turbine I have laying at the house.
