Charlie Swett Posted November 14, 2013 Share Posted November 14, 2013 I have a subaru XT 6(ER27) and a WRX(EJ255 turbo) engine laying around and I would like to put it in the XT 6. What kind of modifications would I have to make? And what parts should I replace? This will be my first engine swap, by the way. Quote Link to comment Share on other sites More sharing options...
Charlie Swett Posted November 14, 2013 Author Share Posted November 14, 2013 It's an 07 wrx by the way. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted November 15, 2013 Share Posted November 15, 2013 you need the turbo engine wiring harness and body side wiring harness sort, trim, prep, and label all the wiring (or pay someone on here to do it) splice and install EJ wiring into XT6 ECU adapter plate to mate the EJ engine to the ER transmission - or an EJ transmission with matching rear differential gear ratio cross member will not allow for stock exhaust routing, need to cut/notch/weld existing crossmember custom exhaust Quote Link to comment Share on other sites More sharing options...
Arfrce Posted April 17, 2014 Share Posted April 17, 2014 so grossfary you have done this swap before? Or have been a part of one? How did it turn out? Is the XT-6 drivetrain capable of holding the hp? And well is it worth it? thanks Jeff Quote Link to comment Share on other sites More sharing options...
MilesFox Posted April 17, 2014 Share Posted April 17, 2014 The xt6 trans is rather strong, supposedly stronger than a wrx 5spd, but altogether the same basic architecture. All of this that applies is general knowledge when it comes to putting ej engines into gl/xt bodies. There are plenty of examples of ej22 engines stuffed into gl's withthe same modifications mentioned abve. It would be less work to use an already turbo xt or swap in a turbo crossmember into the xt6. For example, i have an 86 gl coupe, with xt6 front crossmember and suspension/driveline, with an ej251 from an o1 impreza, withthe same wiring harness chop, bellhousing adapter, and supporting mods you will be into. Searc around for topics related to 'ej swap' find the tutorials, and that will be your basis, and then the specifics tot he wrx turbo engine applied to that.

idosubaru Posted April 17, 2014 Share Posted April 17, 2014 no i haven't done it, but swaps are common. go to subaruxt.com there's quite a few XT6 and XT swaps there. i don't even know how many, but yes it's been done. the transmission will hold up fine if you drive gently. if youre racing it the transmission and clutch are going to be a weak spot. you'll fall somewhere in between that so i'd say the transmission is probably going to be a weak spot.
