as far as cooling goes, ive only heared good thigns about koyo, and henry from mazdatrix runs a second oil cooler in his TII. hes run it long and hard on hot track days with absoloutly no problems. its a fairly easy mod, just get a second cooler, hoses, mounting brackets, etc.

Welcome to the forum.
It sounds like you have quite a beast there.
That oil cooler suggestion is right on.
The rotary engine gets nearly half of it's cooling through the oil.
The top & bottom ducting covers in front of the radiators are critical.
FWIW the stock engine driven fan & shroud pulls way more air than any electric fan.
