Does any one know the stock turbo measurements of the compressor and exhaust wheel?

I'm trying to stay with a stockish sized turbo or some where in that range, and I have a holset hx30, and I want to see how they compare. I believe they are extremely close.

Hx30- compressor: 44mm inducer 72mm exducer turbine: 74mm inducer (forgot exducer)

rb20 compressor: 42mm inducer 59mm exducer, then I forgot the exhaust side, but it was in the 60mm range.

And does any one also know the rb25 turbo measurements? Ive heard the Z's t3 and the RB25's are the same turbo size, the RB just has a ceramic exhaust wheel.
