Anyone know what impedence fiesta xr2i 1800 side fed injectors are?

and what impedence are somethin like ermmmm, fiesta beiges?

need to fuel to about 250bhp - just for safety margin and need to know the impedence of side feds so i can make the necessary changes - problem being the existing ECU will be staying hence i need to know impedence or if a standard 130spec XR3i ECU (cos thats whats fitted to the XR2i) can take different impedence injectors if need be.....if you see what i mean


cheers
