Overheating/coolant loss on long trips

hmm. well they spec out at stock bore (83mm...) so idk how they could be .50mm/.020 over. both sets are stock bore for a 7mge, so now im really confused.

as far as i could find, the crown only used the 7mge for 4 years, 87-91, then they switched over to the jz series or various other 4 cyl and diesel motors. doesnt say whether they were high compression, but since it would be a jdm motor, its very possible. either way, its too bad we cant order pistons like that for our 7ms. id buy a set. might strip these down and use them on another block.
