Wrong...very wrong. There are MANY other differences, as detailed in many threads in this and other forums, as well as the original 'yota docs:

Crank yes (same in 2jz-gte and 2jz-ge). Rods I can't say 100% for sure (since I don't work on very many n/a's), but I'd guess that for only 600rwhp: yep.

Whoa hold on there. You do realize the 2jz-gte head requires a totally different ignition system, and a different exhaust manifold (due to the port spacing), right? I'm pretty sure that the ports for the intake manifold are different as well...

A 2jz-gte head will flow 600rwhp no prob, with no porting & polishing.

With pure methanol you could probably run 11:1 and turbo it too. Pump gas is a totally different story. It all depends how much boost you're going to run. Normally, the way you make 600rwhp with a 2JZ-GTE, you run 8.5:1 pistons, about 25psi of boost, and 100 octane race fuel.

I'll get into as many specifics as I can...ask away...
