Z1 GT600R vs JWT530BB

Anyone have comparative dyno charts between the two? Z1 claims their GT600R is "similar in design and performance to the JWt 530BB". Being the skeptic I can say the JWT Sport 500 is "similar in design and performance" to the 530BB (they *are* similar, the 530BB uses the same case but a different wheel).
My gut feel is the GT600R makes a little more power and has a little more lag than the 530BB, but I prefer actual data vs my "just a guess".
I am more concerned about lag than outright power. 100-200RPM's difference in lag I can live with, 500RPM or more I cannot.

To my knowledge:
Z1 GT600R = Garrett GT2860R
JWT 530BB = Garrett GT2554R
Both turbos get reviews that include quick spool up but the 530BBs are often described as having "no lag" although I don't know in comparison to what. Also owners of both turbos often have a substancial base of supporting upgrades aimed at quicker spool up as well. Either way, lag is subjective. I gather you enjoy quick spooling over more power? If so then I would say get some GT2554Rs from a Garrett dealer (www.atpturbo.com, www.tialsport.com) and run them. Dyno charts are a bit spotty since both are relatively new to the Z community but there is some decent dynos to be found on twinturbo.net.

Awesome, that's even a better answer than dyno charts. Thanks!

A sidenote about the GT2554R turbos:
If you search the subject on twinturbo.net it seems that there was a compression map posted on Garretts website that indicated they would be a great turbo for the VG. However this map was changed at some point and the new one does not seem to reflect the results the people have gotten with them. Just as a heads up.
