Actually when you boil it out, that number is not really that large, the problem is, a mechanical pump won't give the constant pressure needed to operate the electrically controlled injectors, they need a constant pressure, whereas the mechanical injectors rely on the barrel valve to regulate the fuel to the nozzles, that's where I feel the problem would come in, I'm not real interested in parting this setup out, I have the complete setup off of a Toyota that was owned by Bob East, and was supposedly the first midget driven by Jeff Gordon! It's quite a piece of work, huge bodies, machined from billet aluminum, Enderle injectors/nozzles, the ones you can change the hole size with out changing the injectors, got everything from the air filters to the head!
