If I purchase a T3/4 Hybrid in a T04E/B housing will it bolt up to my S5 housing?

Please see the following link at Unleashed Turbos.

Is the E/B better for our engines?

What trim should I get?

I am new to the turbo side and am having some difficulty following all of the different turbo options.

I have a RB catback, pre-silencer, downpipe, rtek chip, kn fipk filter, walbro 255 lph, rewire of fule pump, tb mod - polished and ported
