This was posted in another thread, after I wrote my reply I figured I should start this thread now. I was going to wait till i could have a good basic plan on how to get this done, I still have blanks to fill in.
Please keep any comments like: That's a stupid idea get a subaru. To yourself.
Anyone have well thought out ideas To get this done?

You said the AWD is adjusted from the rear end somehow.. i wonder if the ratio can be changed with a simple gear change?
As far as the ECU goes, you should be able to flash straight to a MS3 ECU without having to replace your MS6 ECU is you went with manual AWD control. This should save the wire nightmare at least. I succesfully did this to my Focus SVT. I went with a Focus RS setup and the flash went fine. Ive also seen this done with various Ford trucks & cars.
I have done a little looking into this for my speed3. It looks like the transmissions are only used in our cars (3and6). The 6 has a power sending unit that I believe bolts onto the 6's transmission. My hope is that it will bolt onto the 3's transmission as well. I am going to get the shop service manual for the speed 3 and 6 transmission it is a seperate manual from the shop manual i allready have . It is the same manual for both cars. with this manual i will be able to see the exact differences that are in place to put the power to the rear shaft. The things i do Know ARE:
Power is always sent to the rear drive shaft(50/50 looks very promising)
As for that last question. No the rear differential needs to have the same gear ratio as the front; the wheel speeds have to be the same. A diff is the only way to split power front to rear
The power sending unit it is watercooled from the factory.
There is no center diff (like an STI) the power is always going to the rear diff.
Then it is utilized by an electromagnetic clutch to use up to 50%.
With this system permanent 50/50 could be atianed with any type of rear diff. Problem is we need to find out which diffs are available with the right ratio.
Also with 50/50 wieght could be saved with lighter simpler rear diff.
That is cool what you did with focus.
Problem is our engine management is so tied in with the steering abs and every other sensor one could imagine.
I do not know how simple it would be to do something similer to what you did with your focus.
I do not want to post any misinformation.
When I have found out everything that would need to be done(or close to it) to make a 3 50/50 awd I will start a new thread.
This I am sure will take a while but I am slowly finding out how it works and what parts solutions will have to be incorperated into such a project.
If anybody reads this whom has also found out useful info maybe start a thread i am not ready yet i need to get that manual.
Please do not reply get a subaru. I want a MAZDASPEED 3 AWD. Anybody ever starts talking about this thats all you hear.
