I am not advertising for these guys, these are the prices they gave me, for a MS2 or MS3, MS2 will run the engine ok, the difference I think was the MS3 can fire the injectors sequential and the MS2 batch fired them. You don't need the wide band 02 sensors if you are going to get a tuner to do the final tune as they will have one to screw into the exhaust and monitor the mixture.
So lets say engine for a good one from a junk yard $500 and MS2 at $476 and a tune $150?? you are all go for less than the injection system with an engine capable of making more power than a LA engine.
