toyota do at least a 20 thou (0.5mm) OS piston.
for the smaller dish, part number is 13103-16131 (i think)

Yeah, but are they forged?
I was told they are made out of the same stuff as the standard ones. Are the standard ones forged?

who told you?
remember the 4AGZE broken piston analysis thread i started? i cut up broken low and high compression 4AGZE pistons. they are both forged and coated.
a brand new 4AGZE high compression piston (0.50 OS) was purchased fro me to cut up and analyse as well... although i have not had a chance to do that as yet, i am 99.9999999% certain that it is forged as well....
standard Toyota 4AGE pistons are forged.
it appears that oversize Toyota 4AGZE pistons are also forged.
they are too cheap i think this is only because of the manufacturing numbers toyota has, as opposed to aftermarket piston suppliers. i do not believe they are any lesser in quality. and for about $100 each, they are a bargain.
