I've yet to see any substantial proof that the DE(T)(TT) engines have a factory forged crank. If someone can prove that they are with some conclusive evidence, feel free, but I have yet to find any. Sure they have seen a ton of power, they were treated a few ways from the factory to be stronger, but forged? I'd like to see proof.
Also, to the guy with the DE crank... would you mind measuring and documenting the measurements of it? I'm very curious if it will fit in a VG30E. Please let me know if you have the time.
