Looks like the racks are interchangeable, from a visual standpoint, likely they bolt in and depending upon the ration, would work.
Don't quote me but I can't find my convo with Mr. LancerProject, but he was talking about using a steering rack with the same ratio as the turbo's.
If you find a rack in this generation that bolts up, the tie rods could be swapped, if that is even needed, and you can get a better ratio.
I'd love to do this to my Subaru Legacy right now, because a 90 degree turn means having to lock arms in one direction, wheres that wouldn't have to happen with my Colt. I'm sure I would have to swap in an Impreza rack or something of the sort. Because Subaru is apparently like Legos or something.
Anywho, there are options ringing in the back of this old brain. Cobwebs getting tugged on dating back to 2004, and some time recently.
