ok so what would be the limit of stock prepped rods?

Ok I'm a bit of a newby to turbos and was wondering if we had 3 prepped RB25's and bolted the same HKS 3040 turbo to each motor but had say a .6, .8 and a 1.0 rear on each turbo what would the difference be on each power wise ie low down, mid range and top end which ar would give you the best average power? what would the gains/losses be? would this govern how much boost each turbo is capable of being efficient at? If each turbo is say rated at 550hp how is this possible with 3 different rears or does this not effect the over all power?

I've noticed some great power figures popping up lately from some well set up RB25's such as b-mans etc and got to wondering what would be the power limit of a balanced, forged pistoned and shot pleened rods cryo treated etc bot end For instance would 400rwkw be out of the question?What rpm is a prepped RB25 bot end able to rev to without shortening the life of the motor to much? Please don't go into detail about how much it will cost etc or 3 litre would be easier to do it with as I have read the 3L thread from back to front and agree it would be easier and probably cheaper, I'm mainly interested in the RB25 limits What would be the power limit of the stock gear box?
