I've given this a bit of thought at well. The steering "reducers" all scare me a bit, I don't want my car's steering going through a component that might not be up to the task.

I have a feeling that an STi rack could be made to work. It would take custom mounts to do it, but if the tie rod thread and steering input spline matches ours then we could conceivably make it work. Google tells me that the SVX has a front track width of 59.1” while the ’05 STi (and I suspect this applies to all 05-07 STi’s) is 58.9. Track width isn’t the whole story, knuckle design, bearing offset and even alignment affect that number, but I suspect they’re close enough that the adjustment in the tie rods can accommodate.

Functionally I don’t really know what to expect though. Another quick Google search got me 1200 PSI as an operating pressure for the STi pump. I’m not sure what the SVX operates at, or exactly how the variable assist works, so I don’t know what the impact would be of plugging SVX hydraulics into an STi rack. Too heavy? Too light? Just bad? CEL from losing the rack wiring?
