Meh I'd argue as you have in the past, there is no penalty for a better handling car. Besides the performance benefits, I'd say building it all the best you can (within a budget/spec) is lots of fun build wise. And building in my opinion is at least 1/2 the fun in owning these cars. If a car came with ACD I wouldn't replace it unless I was building a drag car, would just maximize it best I could. This also stays true to the model line/year of car you have. Work with whatcha got. I wouldn't add ACD to a non ACD car, or mivec for that matter.

I prefer non acd because it less things to fail, to leak, less weight and takes up less space. It obviously provides benefits or it never would've been put into the evo. Cusco used to offer a replacement center diff (they still might) and Quaife does as well. I have no issues getting grip, the car rotates how I want it so I see no reason to add acd.
Mivec would be nice to have but people want so much more for mivec heads and I don't feel like doing all the work to change it over, maybe in the future I'll span that gap but for now non mivec is fine by me.

I got everything for my mivec conversion for $1400. Complete head (sensor housings, cams, reluctor wheels, mivec solenoid, mivec gear, etc), harness, ECU. So worth it. You can get $800-$1000 for your 8 head. Changing the harness and ECU takes 2-3 hours and is pretty simple with the engine out of the car. Now is def the time to do it for you.

I don't plan to pull the ACD in favor of a mechanical diff, but I'd prefer mechanical.
my car is all setup already.
If my tcase died I'd consider replacing with a really nice mech unit, though, depending on price vs an ACD unit.
I've seen both work well, so am.open to either.
Not fighting the ACD line to get to the top tcase bolt would be nice LOL

rally cars run a dry break on that line and dont run that bolt that is obstructed by the acd line banjo... that is why they do a clutch change in 25 min.. 
as for acd vs mechanical.. it really depends on the use... on slippery stuff ACD is really a benefit..

also, the way the car can change direction when sliding around is something else.. cant do that with passive diffs that easily.. Evo's 4wd system is not constructed purely for steady state traction.. if anything it it is about yaw control

I should get rid of it altogether.
I bought a rebuild kit, they are up to $120 now. I was gonna buy another pump to stash away, but they are all $650+ now. Things are getting harder to find and prices are going up.
At this rate, I may as well find a rebuilt non-ACD t case
