74mm turbine in S366SXE

Hello,
Does anyone know if the turbine wheels on all of Borg Warner turbos are interchangeable? I got an S366SXE but I would like the install a 74mm turbine wheel onto it. Link to the wheel below.

No, shaft diameter is different. You can get an 64mm compressor with a 76mm wheel IIRC.

Thanks for replying Turblown. I recently bought a one off s5 turbine that was machined to accept the EFR 74mm turbine and the EFR supercore is a little out of my price range. But it's the only option left it seems beside machining the housing again.
