They didn't have the 7G VR-4 in australia, so your source would be wrong there. the 6A12 they will be playing with is the FTO, which isn't the same as the VR-4, well not identical anyway.
There must be something you're doing to cause all the problems you're seeing with this motor, I have never had even half the problems you're talking about. What oils are you running?, what plugs? how much boost ? How hard do you drive it ? It can also be caused by the air temp and humidity of where you live...
As for forged internals, yes we can get them and most parts for the 6A13TT will bolt straight up to the 6A12TT.
I hear Evo's everyday, I used to work for mitsubishi, and the fact is they all sound the same, same pitch, same pathetic droll no matter what exhaust you're running on them.
Stock for stock the VR-4 sounds better, full 3" back the V6 sounds better.
Tha main reason there are so many parts available for the 4G63 is that it was released in the states, where as the 6A was not. However, there are also a lot of parts available for the 6G in the GTO (3000GT) which is also capable of making huge power.
Have you ever stopped to think though, the ease of making the 4G go that fast has a downside, like huge turbo lag and crappy city driving ?
And try looking to Japan for parts for the VR-4, I think you'll be suprised what you can find.
