When I drive my supra hard or a long distance it overheats. I have had the following replaced. Head gaskets, radiator, thermostat and hose's and still have the problem.

Check to make sure that the tstat opens It could be a water pump like the impeller may have slipped on the shaft. Only think I can suggest is do a pressure check of cooling system it may be you have a small crack in head that is causing it. Also if you have a bug screen in front of car take it off and throw it away as they cut down on the air flow going to radiator. YOu might check to see if there is a fan shroud that is supposed to be behind rad but isn't as that will cut down on air drastically or put an electric fan in front of radiator.
