Looking very nice.
I was thinking SUbaru too, at one point..
Almost makes we me want to grab the saw, run to the driveway and chop the WRX and use it as a donor

but seriously, that is quite incredilble the job you are doing.
The only thing that kept me from that was all the chopping that was required in the rear.
If anyone is trying this and needs with a wrx manual, I do have there service manuals.. I believe their wiring diagrams are in there some where. Just let me know.
