Is my new turbo too big?

Is my new turbo too big?
I used to have a really small Garrett t25 from a 300zx on my 1.8 motor. Decided I wanted more top end, and since I am an OBX dealer, that I would test their turbo's to see if I could sell them. Well of course, being OBX, they're hard to deal with (I don't think they speak english), and there are no specs for their turbo's. Anyways, I ordered the GT28R with t25 housing, and just got it today.... And I'm not sure if it's just because my turbo was so small before, but this thing is freaking massive. The turbine side is 64, and the compressor side is .70 AR... it's a ball bearing turbo... when the hell is this thing going to spool?

take it apart, measure everything, post measurements.

1. I don't believe in "too big"
2. How didn't I know you were an OBX dealer? Got any of the Honda B18 Skunk2 intake manifold knock-offs?
3. You can get an idea by the measurements...but actual compressor efficiency will play a big role. Since they obviously don't test them (or provide compressor flow maps), you're stuck doing real world application-based testing.
In for datalogs of 2000-4000rpm spool in 4th.
