Post VF31/32 Turbo Dimensions

Hi all
Searching for detailed specs and dimensions for VF31/32 turbos for hybrid
Turbo project.

I will list the info I already have found and hopefully someone can fill in the gaps.

VF31
RHF4B46001P11NHBRL3730CEZ

"B" for ball bearing; what type and number of ball bearing ?

"P11NH". 11 A/R ratio exhaust housing, NH material (petrol engine)

"BRL" Back Rake Large ; angle of comp wheel blades

"3730". Size of comp outlet housing in mm

CEZ: don't have this info, seems to relate to type and size of core.

My core housing for the similar turbo I have is:

Turbine flange diameter: 59 mm
Comp side flange: 67 mm
Hub width: 87mm

Turbine size 46.5 mm inducer , exducer 35.4 ? 9 blade ?
Comp wheel 47.7/37

VF32
RF4B46001P18NHBRL3730CE

So same deal as above but 18 A/R ratio exhaust housing
Turbine 46.5/35.4 9 blade
Comp Wheel 52.5/36.6 10 blade

Floating metal bearings ?
What are floating metal bearings ?

This info has come from the net, if anyone could provide actual measurements
For these turbos, I would definitely buy you a beer or 2.

Additionally if anyone has VF31/32 turbos to sell (in any condition)
Please PM me

Thanks
OZ
