Falcon will testament to this, the standard brass (or is it copper) radiators are excellent. I bought a 94+ radiator and had it rodded out. I use it on my supercharged 2gr with no cooling issues until after 20 or so flat out laps.

For a stock turbo or NA it would be perfect.

The cheap aluminium ones are horrible. When I upgrade I will get a PWR

I purchased a PWR radiator for my last SW20 and it was great. Very expensive but excellent quality and fitment. 
It does still have the slightly inconvenient bleed nut instead of a bleed tap though (which the Chinese have copied)
 
I think the Mishimoto would have to be okay since it's been around for a very long time and they should have the fitment sorted.

Further to my post....the Fenix radiator in my SW20 is keeping a 2GR-FE cool without issues :)

Check the fans as well. One of mine wasn't working!!! The electric motor on the left fan was badly rusted, and I replaced it with a electric motor from an early model Camry (just had to swap the plug but the motor was the same size)

To test the fans the repair manual says to unplug wiring to the temp sensor, then turn the ignition on, and the fans should run. In my Bathurst, only one fan run with this test. I also had to turn the air-conditioning on as well to make both fans run.

Thats right then, non aircon cars only come with one fan.
