People bend rods in 2jz at only 650whp with 500tq with improper tuning and also using to small of a turbo to make larger power it happens more often. I wouldn't say I see bend rods on poorly tuned cars as a reason to state that the rods in this motor are weak. How ever I guess you would see more of these than I ever will.
