(Bakmans has a exhaustmanifold and VF12 ready for my MX-6)
So do I.
In effect this hybrid is a VF12 eccept that it bolts to the MX6 manifold.
VF12 wheels, VF12 centre cartridge, VF12 compress cover & MX6 turbine
housing modified to match the VF12 turbine housing.
So why make a manifold again? To spend more money?
Aaaah Allright.
then is clear for me why you choose this way for doing it
Here is a couple of comparison pictures.
All ready to bolt in, with VJ11 wastgate actuator & water pipes.
Just waiting for the missus to get back with some hose so I can replace the coolant feed & return.
I've been digging and can't get any solid leads on it or a rebuild kit for it's center section.
The VF12 can't be found in the USA it was only ever on the 2Lt Subaru Liberty RS.
As delivered to Australia, New Zealand & Europe.
The rebuild kit should be the same as for the VJ11, they are the same family of turbo.
The only thing that may be different is the bearings,
there are apparently 2 different widths of bearings for different RHB5's -
according to the place that I got my rebuild kit from.
If you are looking for this turbo you should also be looking for similar sized RHB5's
Such as VF10 (easier to make since it has the same turbine as a VJ11)
VF8 very similar in size to the VF12.
Also Ferrari 208 (spec # unknown) basically the same as a VF12 eccept that they cost about $800 - $1000
Whereas my VF12 was found for AU$125 + postage.

Reason: added info
Well it's in, haven't test driven it yet because a ran into snag 1000.
The pins on the wastegate solenoid plug came out of the plug.
Can anyone tell me which way around the pins go?
Preferrably an Australian 1990 MX6 owner to be sure the answer is correct.
I need this info ASAP if someone can just run out to their car to confirm.
I have already looked in the online manual but the wires are different colours seeing as how mine is a 1990 MX6.
The colours on mine are red and black on the solenoid side of the plug, the colours on the loom side of the plug are red/black and yellow.
I'll post pics of it in the car if I get time tomorrow. We are off on a driving holliday tomorrow so I might not get time.
Ok here are the installed pictures, I think it looks quite factory - but nicer.
All factory fittings are used: wastegate solenoid, oil inlet & outlet, coolant inlet & outlet.
Please excuse the inlet plumbing, most of the couplers are temporary until I get the time to have the pipes welded together.
And yes that is my BPV swinging in the breeze with the vacuum port blocked.
I have 2 x 1" aluminium hose ends to weld into the pipework just need to find a Forge BPV to install.
From above.
From side.
And for those wondering what IC I am running.
It's an AUTOBAHN 88 (18" x 12" x 3" x 3" ports) All A/C parts remain except that I changed the fan to a thinner one.
Pics.
OK signing off now till the weekend. Keep the comments coming and I'll reply when I get back.
Can you please ask your machinist for exact spec on what and how he hoens the center cartridge? Angles and sizes too. I have a good exhaust housing and I have my VF8 that I want to get done. I have a feeling that the compressor and turbine wheel are goign to be either very close, or exactly the same as yours. The thing with the machine company that I was going to use, they do good work but don't deal with a whole lot of turbos. Not that that should matter much but...the VF8's don't come around EVER and this one is in too good of condition to ruin off shotty machine work.

Not really I simply gave him the VF12 exhaust housing as an example to machine the VJ11 exahust housing.
(Nothing needs doing to the centre cartridge as long as you use the VF__ one)
Seeing as this was done on Saturdays during his regular work.
He probably just wrote down his measurements on a pad before entering them in the borer.
AFAIK the bore diameter he measured off the VF12 was 1 -7/8" which he machined the VJ11 to a couple thou' undersize to allow a little meat for clean up as required.
The bore end face depth was machined to match the VF12 as shown in my post.
There is no angles to worry about just a simple round at the bore end.
Which he also did a little undersize to allow for cleanup.
In the end the turbine is a very snug fit but doesn't rub at all.
If you use the VF12 / VF8 centre cartridge no machining needs to be done to it.
That is the way I would go, you will see when you dissassemble your VF8,
that the compressor back plate is a little different in shape to the VJ11,
to suit the larger A/R compressor housing.
