I believe it did drop temps by a few degrees (nothing drastic), but I really went to a Rod Davis for having no plastic tanks. Keep in mind that I went from a new OEM radiator to the Ron Davis, if your current radiator is old you will see some extra cooling.

My engine is a new short block from Toyota and a rebuilt head. I flushed out the rest of the coolant system and dropped in an RD radiator. I run a stock fan with no modifications to the clutch. I don't have exact temp numbers (still have to get a better gauge installed), but I have never been concerned so far in the ~13,000 miles I have on the engine. I live and wheel in New Mexico. Summer Temps frequently in the high 90s.
Of the 5 yrs running RD in my 91, never had a problem with it overheating. But it did get hot last year in 100 degree summer climbing the Sierras up Tahoe and temp went up to about 220 F or so and i ended up blowing my tranny. I would just run OEM for the 1FZ since they are still avaliable and call it a day, RD is overkilled for mall crawler and overland types application IMO.
Update: ordered the Koyorad A1918 - 2 core aluminum radiator with plastic tanks from 1-800-Radiator for $274.32. They have a local presence so I will get it tomorrow.
I called Koyorad and they said 1-800-Radiator is an authorized dealer and one of their biggest distributors.
They have another Koyorad model for the 80 with all-metal tanks for about $750. The tanks are brass and the cooling element is copper. I thought about it for a moment, but metal tanks for more than double the price doesn't seem like a great deal.
My last radiator lasted 15 years.
