we had the exact same problem on our kraftwerks boosted project!
we installed the low temp mishimoto thermostat to gain some extra cooling, after only 3000km the thermostat failed like yours, leaving us with 2 blown headgaskets!
we now also have back our original thermostat in it.
after that issue happened i had a supra mishimoto thermostat on order for a 900hp project, when it arrived it wasn't flat on the mounting service, it was bend where they are pressed together. so we did not use it.
don't think i will use them again, my confidence is gone after 2 parts gone wrong in one week....
if they want to rectify this problem, they can contact me direct for pictures, the GT86 project we had to pull the engine, replace gaskets and bolts, had to resurface the heads, .... because a stupid new "racing" thermostat failing!! $$$ very costly mishap.
