2005 Scion tC - 05tcBoost!!

This is my 2005 tc. Complete with a few bolt on mods. This car for me has been somewhat of a battle. Previous owner was clueless on what he was doin to this. I have aplans for this thing im just unsure of where to start with it. I wanna do some engine work. More a performance based project rather than a show car. Anyone on here with boost and words of wisdom i will gladly take it. Im currently in hawaii and returning to the mainland soon. Takin her with me too.
