Can you hybrid a VF11 with any turbo?

Thanks!

you most certainly can...I used to have a VF11 hybrid that I ran at about 15 psi and made great power, and spooled instantly.


What you need to do is find an IHI turbo off of a 1987-88 Ford Thunderbird Turbocoupe, and the compressor housing will bolt straight on and give you a 90* outlet as well as a bit more capacity to move some air!

555BCTurbo You are the man! For telling me about this T-bird mod!

Now how hard is it to find a T-bird compressor?

I dunno what type of Turbo it is BUT i did find a interesting site:

RHB5 FAMILY TURBO INFORMATION

from Mazda323performance

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:
VJ14/16/17 = 12r (VJ16/17 have freer flowing wheels?)
VJ11?/VJ20/VF10/VF11 = 15r, larger wastegate port? (*note*: the VJ20 does have a larger, octogon-shaped inlet)
VF8 = 20r
VJ23 = ??

VF11 Turbo Specs:
Inlet Diameter: 2"
Outlet Diameter: 1.75"
Air Flow Rate: 1.4 - 10.8m3/min or 49.4 - 381.4ft3/min

Turbine: 0.52 A/R, 40mm trim
Misc Numbers:
Turbo Spec. VF 119006
Serial No. RHB5 14055W
Parts No. 14412AA070

Warner-ISHI RHB5 (T-bird turbo) Specs:
Air Flow Rate: 1.4 - 10.8m3/min // 49.4 - 381.4ft3/min
Max Pressure Ratio: 2.8
Maximum Speed: 180 x10^3rpm

Yes thats one HELL of a post. But it raises the question of can i hybrid any old VF/VJ family of turbo to my exsisting VF11? Does any one know if i can stick a VF8 compressor onto a VF11?

Thanks!
