I have a 92 Justy, front drive, 2 dood 5 speed. I am thinking about swapping out the drivetrain from a WRX or regular Impreza into it. I have seen a couple youtube videos of justys with a WRX drivetrain, but no build info. Another option would be to find a 4wd transmission and the rear diff and drive line, and build up the 3 cyl, maybe turbo? are there any other engines that will bolt to the trans, like Suzuki swift 4 cyl? This is a daily driver now, but the motor is starting to get tired. I am looking into this as a winter project, soon as i can find a Forester or Outback wagon for a winter car. I know either option is a major undertaking, but i work on cars for a living and have the shop space to take on a project like this. Any advice would help a lot. Also, where is a good place to find parts for Justy's? Its harder to get parts for than my Porsche.
