they would make your car run too rich. you do not need anything that big unless you are getting the same % increase of air as you would be fuel. if you can get more pressure in your fuel line then your pulse widths will be longer and you'll make more hp with the same injectors. i don't know what either one is good for but i do know that the ecu your running can't control the turbo injectors to work with the setup you have. as long as your car isn't cutting out or backfiring then you don't need more fuel. if you switched to turbo injectors then your car would feel sluggish and weak b/c it's too rich.
