I've had this problem with both of my turbo Supras. I found a radiator shop that built me a couple of 3 row radiators. They helped, but the cars still run hot in the Phoenix summers. I changed the fan in the 1990 to a direct-drive stainless steel flex fan, and that helped, but it's a bit noisy.
In the summer, at ~110+ deg., both cars get up to ~220-230, on accurate gages, and the faster I drive the hotter they get. I run 50% antifreeze to keep the boiling point high. Both cars have good head gaskets. I am convinced that Toyota screwed up and should have provided for a lot more airflow thru the rad.
