Message	If you were able to get the injectors in the head, you would still have to figure out how to get an ECU to properly control the pulse timing right without blowing up the motor. Direct injection alone won't get you much, the extra power often comes from multiple injections carefully timed before each ignition to get proper atomization and cylinder cooling.
