Strongest IRS rear end set up possible?

Ok, short of doing that solid rear axle swap I was talking about, what would be the strongest rear end set up? Keeping the stock style setup would be nice, so let's see it. What would your "dream" rear end set up be? Remember, it has to hold 400+rwhp full time, and 700+ rwhp when I hit the bottle. As a side note, I get cryogenic services at cost, so any set up I go with will be deep freeze treated, which enhances longevity substantially.

As always, thanks for the input!

THere is a setup using a Corvette differential mated to the RX-7 IRS shafts.
You can see it at:
It also gives him the choice of many gear ratios.

The issue here is not the strength of the differential. I've NEVER seen a TII differential break from too much HP. The axle shafts are a different story. I THINK Rotary Performance was working on some stronger ones for the TII- they have them for the FD, and they put 650+ to the wheels. They DO still break them sometimes though- the weak link is that the little output shaft that goes into the differential is still a stock part, and it isn't particularly beefy. That's what breaks.
