Also curious about transmission and diff compatibility between IS200/300/RS200 so I up this ...

TRD do this but the prices are a tad steep

[Johan]

How about compatibility? Are the LSD for IS200/300 and RS200 exchangable? Could it be they're one and the same even?

From what it looks like only the IS200 Manual Gearbox and the ALtezza RS could have the same diff ratio (top speed vs. revs ratio) as they have the same gearbox. That would be my guess. The diff ratio for is200 auto and is300 are different.
