I think the ports do the same as the Garrett anti-surge compressor housing. However, it looks to me that it was a post manufacture change made on a regular compressor housing (i.e. drilled out). Unfortunately the A/Rs are fixed (i.e. .68 for a GTK650) - however, i am looking for quick street spooling anyway. I have been considering a GT4088R, but I am thinking of trying the GTK. From the sizing, it seems that the GTK-550 is between a GT35R and a GT40R.

Just got a response back from a vendor this morning...
I am considering a GTK650 but I may be waiting a month for the order. But some GTKs are shipping -- He has one GTK550 in stock.

Anyone recommend a vendor?
