It always seemed like the GT owner was getting the better end of the swap to me.
Both owners are usually getting what they want though...
The advantage of swapping to a SRA is that they can be built very strong, for very little money, using common factory parts, as opposed to the IRS, which requires a sizable investment, using aftermarket parts, to achieve comparable results.
If it were me, I would wait until I installed the turbos before I seriously thought about swapping the rear end. That decision would be made with the hindsight of knowing that a lot can happen between now and "Eventually, down the road".
If you do, eventually, decide to swap to a SRA later on, you shouldn't have any difficulty finding a GT owner to trade with. You might even try to find someone who has recently rebuilt their entire rear using 31 spline axles and differential, ideally, that way you would end up with a bullet-proof setup out of the trade.
