Dont mean to rain on your parade but the turbos you got will be a lot more laggy then the 2530's but they will give more power. I was very close to buy this but after some investigation from Airtune they told me that these turbos a re little to big for a 2,6(if you want good response) but good for a 2,8.

I don't how much of this is correct, but they flow more power than the HKS GT2530's and they are more responsive as well. I've been told that a guy in Japan dynoed his R33 GT-R (?) to 738 PS @ flywheel.
I've also had the opportunity to experience the characteristics of these turbos compared to the HKS GT2530's, and the Garrett ones seemed much more responsive. Both setups were mounted to the same car/engine, and according to the owner no other changes had been made to the engine in between.
A friend of mine also ran the HKS GT2530's on his Rod Bell tuned R33 GT-R, and my impression was the same there (that the HKS ones are less responsive).
In the end it doesn't really matter, as I'm not looking for high power figues (anymore, I was in the past) but rather a responsive car with more emphasis on drivability, durability and driving experience. As long as they can make 600 PS I'll be satisfied.
