it's the xforce !!! idk but this car was a turbo car ! so yeah....
about the high milage ! you can check with the orther subaru and see that they still run perfect till 400k km :-S mostly subaru is for daily drive + a little bit of power !!!
but if you want you can rebuild it with around 2-3k as quote but i dun think that i need to rebuild this for another few hundred thousand k ! it drive perfectly for me ! would never have any problem !
the RWC was done on 3/11/11 and there's no oil leak or problem !
just 1 problem is the Angel eyes was fall out due to lack of glue ! you can open the headlight to stick it back easily if you like or just leave it like that !
