After seeing a couple of people here lately have some issues with radiators(I don't remember if they were the same or not) I think we should post feedback of what radiator you have, if modifications are required to install, and any drop in water temperature after installation. Overall, the stock radiator in an FD normally does a sufficient job cooling, I replace them due to the end tanks being plastic and brittle. Here are the ones I've used:

Fluidyne: Very well constructed, direct bolt in-no modifications required, water temperature dropped a 2-3 degrees if I remember correctly. It's a little more on the expensive side, but if you run into a deal on one I would buy it over a standard Koyo. Has a drain plug on the bottom

Standard Koyo: Also very well constructed, mine bolted right in... I have heard some people have had to make modifications to the mounting brackets to fit. The water temp dropped a few degrees. Has a drain plug on the bottom.

MazdaComp: Very similiar to the Fluidyne. Very well constructed, direct bolt in with no modifications. Temp drop is a few degrees. Normally on the expensive side, but if you find a deal I would buy it over the Koyo or Fluidyne. Has a drain plug on the bottom.

Koyo N Flo: Triple Pass radiator. Best cooling radiator I have used. I have this on my track car(Pettit CC III and no AC or PS) and no modifications were needed when I installed mine. However, I'm told that most cars will require modifications. I can track my car for 30 minutes and the temp will never get above 85. On a 70-75 degree day, It will stay between 81-84 on the track. Has a drain plug on the bottom.

Those are the ones I have used. Please add your experience, either with the same radiators that are posted above or ones that are not mentioned. I know Landers had some issues with a radiator not too long ago and Chad had to make some modifications to his as well.
