2jz ge/gte bottom end and head ??
Just out of curiosity, I wanted to know the differences in the bottom ends of the 2jz GE and GTE. The only info that I could find is that the only differences that exist are the pistons (comp.) and oil squirters. Thus does this mean the bottom ends can handle the same amount of power and rpm? Are stock rotating internals forged?
Also I have read that the GTE head flows better. I would assume that the GE has smaller intake runners and there is probably a difference on the exhaust side of the GTE to help with turbo spool. Any specific flow numbers or anything else? I just ask these things so that I can be better educated about the 2jz, I don’t plan to do a swap or buy a supra or anything.

Chris is correct in saying the GE head flows better.

Stock GE head
lift---------intake-------exhaust
.100------91.8----------69.85
.200------161.33------130.38
.300------197.4--------154.23
.350------205.6--------156.35
.400------208.8--------157.62
Stock GTE head
lift-----------intake-------exhaust
.100"-------- 81---------65
.200" --------155-------122
.300"-------- 199-------145
.400"-------- 207------151
To answer your other questions. Yes they can handle the same amount of power. The only other slight differances are in the water pump since the NA feeds the head from the driver side and the TT from the passenger side. The NA block is not drilled for the oil feeds for the turbo since there isn't one. Also the oil pan is not tapped for the oil drain.

do the guys who are running 1000+whp need to run billet main caps?
also, the reason I am asking these questions is because when I was on a late model team (dirt track) we had to do some things to the block so that it could handle the power, like splayed billet caps onto a 2 bolt main block. of course the block had to be worked on for this. I am just amazed how a stock block and bottom end can handle so much power straight from the factory.
