Hey guys/chicks!

As you might know already i know bugger all about this sort of stuff (but willing to learn ) and sorry if there is already a thread like this!

As the title says i am thinking of putting a turbo in my impreza r. Does anyone have any advice on whether i should or not with all your experience? Some people have told me that i would have to change a lot in the engine and not worth it. is this true?

Thanks
Jenna
