honestly id just sell that one, and use that money to put toward the upgrade to a gsx...youve already listed enough (not go fast) parts that you could use that money plus the money from the car itself to snag a nice gsx.....my buddy has an almost all stock gsx(other than intake exhaust and some tuning) only runs like 13psi boost and it is suprisingly quick, itd be a huge upgrade from the none turbo youve got now
