I’m building a kit car and as part of the build i’m rebuilding my ej25. i’m relatively new to Subarus so i’m trying to find some help picking out parts. I’m trying to be able to comfortably make 400hp to the wheels. i’m already replacing all of the gaskets, bearings, and hoses. If anybody has any advice on what i should put in this engine it would be greatly appreciated. i don’t really have a budget but i don’t want to spend crazy amount of money. Thank you everybody!
