I'm thinking a 2.4L built bottom end bored and stroked out of a Galant with your current 2G head. 22-29lbs of boost, didn't search on your turbo but if you don't already have one try a ball bearing turbo (Maybe a GT35R), and a full tune. If you come to a stand still I know there's one 2G on youtube at 1000AWHP. Talk to him, maybe get some pointers. After that call it a day and post up your dyno numbers.
