Ford PCM's use PWM to fire injectors. The impedance of the coil inside the injector itself has a specific rating to flow the flow charts in the PCM. If the impedance rating doesnt match you can severely overfuel or under fuel a cylinder with the wrong injector.
BTW, FMS makes the injectors I would need @ $600 set.. Ouch.. Maybe time to setup for pump fuel..

Its pretty much the same thing as Ohms in a speaker. Injectors are solenoids which just take duty cycles in milliseconds.

E-fans are so damn expensive! I was thinking about getting some, but after seeing most are like 800$ or more I opted out.
I actually got a lightning fan shroud a few days ago from one of my buddies. It looks at least 2 inches more shallow. So you can fit a bit more inside, but you have to extend the shaft on the waterpump or change waterpump all together so the fan actually fits inside the shroud.
Another alternative is to use OEM e-fans from a 05+ silverado in conjunction with a flexalite variable speed controller. This guy with the setup says it costed him 175$ for evreything. I can post pictures if you want. Just don't want to clog up your thread. But it definitely saves some engine bay real-estate while keeping it simple and cheap.
