987687 Posted March 27, 2013 Share Posted March 27, 2013 (edited) You'll need transmission, front axles, driveshaft, rear: subframe, diff, axles, and hubs. It would be a fairly involved conversion, but not impossible. Just bolt on bolt off stuff. And I don't know if a fwd legacy has a carrier bearing support, you may have to weld one to your car. The FWD gl doesn't have it. Edited March 27, 2013 by 987687 Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted March 27, 2013 Share Posted March 27, 2013 you also need the TCU to control the transfer clutch. i don't know if adding a AWD TCU will do it. when swapping back the other way in the later 90s, you always end up with a TCU trouble code. the TCU is look for the rear speed sensor. and i have heard it suggested that the harness tells the TCU / ECU if the car is FWD or AWD. not sure. but regardless, in addition to the hardware you need the brain to control it. you may also need the gas tank, not sure if they are different. much easier to put your engine into the AWD car.

987687 Posted March 27, 2013 Share Posted March 27, 2013 He said 5speed, so it doesn't need a TCU, your left foot and right hand are the TCU 1 Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted March 27, 2013 Share Posted March 27, 2013 Fuel tank will be needed as well... One of our forum mods has done it, Legacy777 here is his web page with the write up http://www.surrealmirage.com/subaru/swap/swap.html Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted March 27, 2013 Share Posted March 27, 2013 Yeah, my write-up has a lot of details. If you are not converting from AT to MT or if you're already MT, just ignore the MT section of the swap. If you have questions, just post.

14D Posted March 30, 2013 Share Posted March 30, 2013 (edited) Are the front axles interchangeable? I had read on here that the FWD axles had a different spline count. If its only different on the engine side I guess it wouldn't matter. I wish my car was AWD. I thought about converting it, but at this point I'd be better off getting another car.
