wondering what tuning and size injectors and if mass air is a must to turbo a stock 2001 ford focus its one of my two focuses and just needs more power like my cummins and powerstroke lol what do you guys think? I have turboed mustangs and stuff like that but all used blow through carbs. can i simply make a oil feed and oil return in pan and put bigger injectors and some tuning? or would I need mass air cant remember if it is already or not.
