I picked up a Nissan 14411-91F00 turbo thinking it was a 1:1 equivalent to a GT2560r. Since running it though, I noticed it had slower spool that reported for GT2560R's other places online.

My technical knowledge of turbo specs is a little week. What performance differences could I expect between these two turbos, given the specs supplied?

I've somewhat answered my own question. The 0.80 A/R compressor is an optional upgrade.
