Thinking about putting a WRX engine and drivetrain into my 97 Legacy.

I know the Sedan is slightly wider than the Wagon so how did Subaru achieve this? What parts differ and then, what will best transfer to my Legacy?

I'm pretty sure wheel base and track are the same between sedans and wagons. I don't know why subaru would change it.

I-Speed did the swap on my Legacy. Check out www.EJ20Legacy.tk for pictures and whatnot.

Everything mechanical bolts right up. You don't have to change your stock tranny out, and if you have a 5-speed I would recommend keeping it and just getting a better clutch. The ratios on the RS/GT five speed are MUCH better than the overly long WRX ratios and the transmission is equally strong. That's the easiest and best way to do it. That said, I swapped in a version 5 STI type RA tranny... even with the new tranny and rear diff the stock axles fit up perfectly, so it isn't going to matter if you get your engine from a wagon or a sedan.

There is, of course, like 40 hours of very complicated wiring to get everything done right. I don't think anyone in the country can do it better than I-Speed, but you're on the wrong side of the country obviously. I think Rally Performance has the capability to do the swap though as well....

Great info. Thanks

My car is/was an Outback though. I have a comp clutch but would like an LSD and newer tranny too.

Can it still be done?

If you don't have a lsd now then you will need new axles if you plan to install one from a wrx. My 96 legacy uses female type axles and the wrx has stubs/male comming out from the differential. I think some of the older turbo legacys had the opposite type that would work for you. I don't know for sure if the wrx rear axles will work in the legacy as i haven't tried it yet.
Transmission should bolt right in. Depending on which transmission you get all you should have to do is change around the mounts for it. I think they are different anyway.
Wirring is a bitch. That's why i haven't jumped on this yet and my car is just sitting and waiting for me.

The axle thing seems to vary a whole lot by model year and model and it just seems quite random. A bunch of people say they had to change their axles, and some didn't. I got a rear diff off of a 2001 4EAT Forester or Legacy or something, because the RA tranny is 4.44 and so are the 4EAT rear diffs. Anyway, the stock axles fit right up to it. But some people change 'em. I would check to see if yours are male or female and find an appropriate diff.

Any 5 speed Subaru tranny is going to be a direct bolt up. If you use a tranny from a turbo car though, you're going to need a new slave cylinder and a new clutch and flywheel. Clutches are pull type on the turbo's and push type on the N/A's, and most of the time (but not always) flywheels will only work for one or the other. The mounts for the tranny won't be different at all though... the STI tranny mount I got for an Impreza and put on my Legacy then swapped onto the STI tranny fit perfectly in all cases and is the exact same one used on the WRX tranny.... they'll all fit exactly as they should with no modification. The only one that requires some creativity is the 6-speed because it's larger...
