The C32 injectors will be fine!

I'm not sure about the 78mm fixed pulley. I haven't heard of them being used on the M112K (or if it's meant for an M113K). The stock pulley combination is a 154mm crank pulley and a 74mm clutched supercharger pulley. I'd stick with that, then you can run a stock ECU tune, and you'll have more power.
