Default 88mm s400 install

I purchased a wheel and compressor housing for my s400 . It's a gtx4718 88mm wheel that goes to a s400 frame. I had to machine my bearing housing bigger that was really easy.
The wheel is left hand thread with out a nut opposed to the s475s wheel that had a nut.
So when I tighten the wheel by hand it's almost impossible to spin if bottomed out if you use the same procedure as if you were installing a stock s400 wheel . Yes the turbine shafts is installed all the way with the piston rings inside their bore.
Is this wheel not supposed to be tightened up against the backing plate . My gut tells me I'm not doing something properly.
Any one know the proper procedure to install a billet wheel with the nut part of the wheel.
