engine, gearbox will be changed but ecu would have to be changed then also for different map for a/f etc. . so will the car end of the ecu plug be the same?? will front drives be different because its an sti - thicker etc from the gearbox? doesnt the sti have a front diff aswell but is the rear diff the same in the wrx as an sti - will there be ratio problems? ha so many questions
tried looking but not finding out much. thanx for reply

The driveshafts are no different as far as i am aware, however, if you put the sti box in, then you will need to put the rear diff in too, they are matched, using an unmatched pair will kill it, quickly.
the plugs at the engine end are the same, they are behind the battery.
