I want to turbo my impreza 1999. As I know I can run ej20r if I make it single turbo with standalone ecu but what about the rb25det into impreza how hard is it? And how much it will cost for fitting only? The rb25det can handle 500hp with oem internals so its nice deal but ist too hard to fit it into classic impreza? Need info about that
Thanks

 

As I only know of one that has been done I would guess pretty hard. Possible but difficult. Ask somebody like scooby clinic how much they would charge. That will bring things down to earth...
