Having just fitted my FMIC and oil cooler ahead of my radiator, my radiator is suffering a bit as expected.
For those that have done these mods is merely fitting an Al radiator sufficient?
Obviously the flow through the radiator is not great after modding the bumper and fitting averything, so will look at restoring the flow through the radiator by closing up the gaps between the bumper and radiator.
I've got a BMW electric fan in already running off a Honda fan switch (85deg IIRC) located on the thermostat housing.
