Can the 3sgte pistons work in the 1jzgte.I am looking at if the gudgeon pin is in the same place and if it is the same size.

i'm going to guess that it will not, seeing as the 3sgte has the same bore as the 2jzge/gte, which is a 3.0, and the 1jz is a 2.5L.

But they all have the same BORE of 86mm.

oh snap! you're correct. (not that i doubted you, but i just didn't think they were the same?haha)

however, i'm not sure if they'll work. the wrist pins might be different, as well as skirt length.
