If turbine AR shifts the boost curve, does that also affect the minimum RPM's to gain initial boost?

The normal GT25 turbos have 0.64 A/R turbine. That was why I first said it was a little too big.
But with a 0.35 A/R turbine it is looking like a good match. To know for sure we'd need some more information on the engine that turbo is intended for.
It seems that your turbo shop will be familiar with that engine and have recommended that turbo to you because of that. In short, they know more than we do about this turbo.
But it is always good peace of mind to come to the same conclusion yourself.
