AND, what you posted is what the OP already said he wanted to do. So you basically said nothing.
Uppipe is congruent with getting an EWG setup (GS makes a nice one), and yes I know there are many turbos out there but VF series are simple installs and you can find lots of used STi turbos for cheap (notice the OP wants to limit his cash output).
