Geoff,
The problemo isn't necessarily integrating the pump, it is finding the appropriate pump. The USDM ACD pump does not have provisions for AYC outputs. Now in theory it would be possible to use an Evo X SAYC/ACD pump, assuming that pressure output to the ACD is the same or similar between Evo VIII, IX and X. The one problem that comes to mind is out the SAYC/ACD controller communicates with the ECU. Understanding that the ECU has switched to CAN protocol on the Evo X, perhaps it would not be easy for the SAYC and ACD computer to communicate with an Evo VIII or IX computer... or perhaps it would be easy. If someone wants to sponsor us with the appropriate Evo X pump and SAYC/ACD computer I'm sure we'd be willing to give it a go!

Also,
The hubs (for use with X axles and control arms) from a X onto a VII, VIII or IX might be an issue as I believe it had a different number of teeth on the ABS ring. Again, not 100% sure about that, but it seems like we thought about that option.

this is really interesting. There are a lot of different options that present themselves and believe it or not - a pump and controller are not that hard to integrate. look what the subaru guys do at dccdpro.com and we do similar stuff with the AWD GTR conversions. props to the OP, if didnt have a carbonetic LSD i would be experimenting with this (ie: use the evo X axles and go wide with the control arms)
As a road racing VII owner I´m always thinking about the spare parts.
rawkus - what i was suggesting is to use a different pump, from a different application. ie: attessa skyline pump, or mr2 p/s pump would both work with proper control and regulation. There are ways to work around the axles of course as you already figured out the inner
LCS - there are some creative ways to use "spare parts" on your VII, start measuring different cars and see what you can come up with. I cant post details, but there are some very simple & creative ways to experiment with susp geometry

I don't think Geoff was saying he uses GTR parts in a Subaru, I think he was talking about doing conversions on GTRs and the parts required for that, similar to the DCCD controller people are using in Subarus.

The differential itself is working just fine... but we are having pump issues now we hope to resolve with USDM parts. Will update within a few weeks I imagine!
