A Greddy "T67" has nothing whatsoever in common with the "T67" as used by Precision, so let any speculation end here.
A Greddy 'T67' is a hybrid of a Mitsubishi turbo, which is made by combining the smaller TD06 turbine with TD07 compressor, which is how they came up with "T67" (same thing as a TD06SH-25G).
The TD07S (25G) compressor is rated at 850cfm, but Greddy mates that compressor to a smaller turbine, almost certainly to make things spool faster. The tradeoff is a PR bottleneck before the compressor is done, which limits power in favor of making it feel better on the street.
As for real world performance, I don't have much info, but the actual results I've seen make it appear to fit somewhere between 50-trim and 3076R - but definitely not in GT35R or GT37R (PT67R) territory.

Another misconception is that the JUN cars used a T67, when they really used a TD06SH-25G.
