Thanks guys, sounds like it will be difficult, time consuming, and since i wasn't planning on doing it myself, costly.

Have considered just buying a wrx, but can't bear to get rid of my current model, love it to bits. Might have to just nut up and make the sacrifice.

However, is bolting on a turbo possible/worthwhile? or again, just cut my costs and buy a wrx?

Cheers heaps for the advice.
