They couldn't get the turbo and carburetor to cooperate with each other. The 12si 3 wire alternator was because they needed 1.3amps for the oil pump and I'm not sure the specs for the efi kit but I'm guessing between 3 and 8amps. Pretty much better off starting with an engine with a 10amp stator to be on the safe side, or use a larger ah battery.
