Aren't most modern components cast?

Almost a 100% sure the pistons should be cast. Can't think of a reason to be otherwise, and cast are a lot cheaper.

2JZ had cast pistons, why the hell would this one get forged?

Perhaps the question would be better suited on the con-rods and crank...
Tip: Better to beef up the bottom then waste time at the top. More likely to throw a con-rod out the side of the block then melt a hole through the piston (unless you do something really stupid with the fuel). |

i thought EJ207 and EJ255 and EJ257 stopped using forged internals other than the crank after V7. And all recently built performance EJs from the factory where cast rods and pistons.

The last relatively inexpensive naturally aspirated production car I can think of that came with forged pistons and rods was the S2000.
