cre, ive been curious about this too. the two motors i picked up for my project (88 jdm 7mge, 90 cressida 7mge) both tested high compression while cold! the jdm motor ranged 185-193, the cressida ranged 20-195 (3 cyls were completely boned). when i disassembled the motors, they both had the same type of pistons, but when i compared them to my new pistons, they had considerably less dish in them, almost flat tops. i was concerned that id gotten turbo pistons, but compared them with my freind john's pistons, and mine were definitely for N/A. so somewhere, toyota got a wild hair up their bum and put high compression n/a pistons in some motors.

i had no luck finding these pistons anywhere.. but that seems to be in the same compression range as mine, since his was warm.

sorry that was a lil off topic...
