I have a 1981 3TC that I want to make EFI because my current carb has been rebuilt (half came from a 3tc carb and lower half is from a 4AC carb), it runs great when cold but gets rough when warm, gets rougher when AC is turned on. I understand the best and easiest long term solution would be EFI, I don't want to turbo it, id like to maintain it as close to stock as I possibly can.
I know of the basics of an EFI system, such as the custom intake manifold, ECU, injectors, TPS, Throttle body, CPS (also, how do I adapt a Crank Sensor?). Other than these what do I need? Is an external fuel pump necessary, or can I use the stock one? do I need an IAC valve for the AC to work?
thanks in advance.
