It's available in .48, .63, and .82 A/R on the turbine side, so lag shouldn't be too bad unless you get the .82. .62 might take a little longer than a smaller turbo to spool, but it'll hit you harder when boost "comes on." I don't even know what the max pressure output is, but it should be way more than anything you could run on a relatively stock block. People run these turbos at 20+psi with aftermarket sleeves. I'll try to find a compressor map for you.
