Radiator?
if i had to choose a radiator which one should it be?
Fluidyne? Koyo? or Mazda Comp?
i know that the koyo is installed in the front at the top rather than the bottom but is the installation easy? does the front end have to be completely pulled? and does all the piping fit?? thanks..

All the radiators install in the stock position. You are thinking of people who are using front mount intercoolers and are relocating their radiator.
Just get the PWR, Fluidyne, or Koyo. They all have slightly different fitment issues. The PWR of Fluidyne probably fit a little better than the Koyo.

Blow up or win
Putting in a new radiator is pretty straight forward and you can do it from the top or bottom. I think you have less chance of dinging the fins if you do it from the top, but you'll have to take off more components.
As far as brand I think it depends on your budget and horsepower.
Whatever you do don't buy another stocker....
You can get a double row copper and brass unit that will still cool better than the stock aluminum unit for only $175.00 delivered to your door.
You can go with the Koyo. Fluidyne, PWR, MazdaComp etc. if you are running more ponies. You'll also save 2 lbs. of weight over the copper and brass. You'll get more "bling". (but who will ever see it?) You won't get any more efficiency until you start running at higher speeds. At lower speeds they are actually less efficient since they are thicker and require higher ram pressure to get into their peak operating range. That's why they are considered "race" radiators.
You can get a MazdaSpeed unit for around $1,650.00 but only if you have a huge trust fund and friends who will be very impressed by your largesse.
Me? My car is lightly modded so I went for the cheapo unit but put ALL new hoses, new heat shrink clamps (bet you never heard of them before) a new thermostat, a new pressure cap and a new AST in. I would have put a new water pump in but my original seems to be humming along nicely without any leaks. I ended up spending about $600.00 but I have essentially a completely rebuilt cooling SYSTEM.

The fluidyne works great, and is drop in. I've roadraced and dragraced my 7 with the stock sequential twins in the middle of the texas summers and have never had any cooling problems at all. Temps have always stayed around 85 and not gotten above 100 even when driving the **** out of the car.

With a stock setup I can't say. Mine is using a FMIC so it wasn't a problem at all.
