various turbos, hybrid turbo specs, etc. 4cyl guys

well i was looking on 323 sites seeing what turbo(s) to source at the JY for my turbo install and came across this. thought it would be somewhat useful, and answer most questions about hybrid turbos.
VJ-6 Very early '85 - '86 BFMR Japanese Imports
VJ-12 Early '86 BFMR Japanese Imports
VJ-13 '86 - '87 BFMR Japanese Imports
VJ-14 American BF Model 323GTX (flows 200 cfm)
These are all about the same size. Only differences are the water lines?

VJ-16 Upgrade turbo available in the US
VJ-17 Group A turbo used in the WRC (no wastegate, external wastegate)
I believe these are both about the same size(larger/freer flowing wheels than the VJ14?). Good for 17psi on a 1.6L
Also heard they have larger bearings?

Smaller to bigger:
VJ20 - BPT turbo, sounds about the same size as the VJ16 or 17, good for 15psi on a 1.8L
VJ11 - MX6/626/Probe

VF10 - Subaru Legacy, VF10 is bigger than the VJ11, VF8 is bigger
VF11- automatic Subaru Legacy, same as t-bird comp?
Warner-Ishi T-bird (flows 381 cfm)
VF8 - Liberty RS (larger turbine housing and wheel?)

VJ23 - 323GTR, BHF6, ball bearing, still kinda laggy, someone's making 400hp with one of these

Hybrids I knows, (coldside/hotside) or (compressor/turbine)...
VJ11/14 - Most popular here in the states, spools up 500rpm quicker than stock, cooler intake temps (for larger comp), I've heard it will do 20psi and 19 till redline
VF10/VJ14 - A little bigger, lags slightly more than stock?
VF8/VJ14 - More lag than stock
VF8/VJ11 - Big dog, 300hp turbo; comparable to a T3?

T-Bird comp/VJ16 turbine (sounds kinda like a VJ20 with a VF10 comp?), Kenny Lew runs this turbo, slightly laggier than stock?

WRX/VJ14 - Matt Manspeaker(yahoo lister) said it was good for 20psi, but he mentioned ball bearings? TDO4 isn't bb?? Maybe he has a new IHI turbo?

Garrett GT/VJ14 - Corksport lists this on their site... I've heard of people using these in Australia and NZ. And yes, I'm 99.9% sure that a GT25/28 will not bolt up to a stock manifold.

Turbine Housings:
Don't know if it refers to a/r or trim?? But it's cast into the side of the housing.
Smaller to bigger:
RHB5 series:
(*note*: turbine housings on VJ14, VJ11, VJ16, VJ20, VF10, VF11 are swappable due to the same size turbine wheel)
P12 = VJ14
P15 = VJ16, VJ20, VF10, VF11 (*note*: the VJ20 does have a larger, octogon-shaped inlet)
P20 = VJ11, VF8, VF12 (*note*: VF8 and VF12 have a larger turbine wheel then the VJ11)
P25 = VJ17 mazda rally turbo

RHF6 series:
P16 = VJ23 (RHF6B - 94 3 P16NR5 BRS504AZ)

Question The VF11 comp sounds a lot like the T-bird comp? bad info? What's the VJ11 inlet dia?
