anyone successfully changed out/modify their viscous coupler yet?
Has anyone attempted to change out or modify the stock viscous coupling unit by....
1. changing the viscous fluid within the coupling housing to hasten or slow down the gearing speed
2. exchanging for a more aggressively tuned viscous coupling unit
3. exchanging for a clutch or other type of mechanical diff.
4. upgraded to some kind of electronically controlled differential incorporating 1 through 3?
Is this even possible? are there other possibilities?

No. 1 is virtually impossible. Archer Racing tried that quite some time ago with the 1G DSM viscous. It's not a simple mod, nor was it particularly successful.
No. 2 not available.
No. 3 -- plenty of mechanical CD alternatives available, including JDS Cusco, RS helical, and Quaife, among others.

Cusco and Kazz and maybe Ralliart make center diffs for the EVO. I believe at least the Cusco and Kazz are clutch style diffs. The Cusco unit is available as a 35:65 split to move more power to the rear, but I do not know if this works with the ACD cars or non-ACD cars. Anyone confirm this? I know there are at least a couple people in the country using the 35:65 unit . . .

not so easy upgrade on the 7-9, as the pump is still needed for the center diff.
Also works well on Galant / legnum VR4 type S
