Anyone have comparative results on this turbo mod?

Baseline on a HT3B, then another with the HT4C Wheels installed inside? It's a mod I am looking into for a HT3B I have coming to me shortly......oke:

I was thinking about adding a 3B to my 40 eventually. What will the HT4C wheels change over a "normal" 3B? And is there any machining needed or is it a simple unbolt/bolt back in swap?

Is it a standard -40? Or is it one with the S300 shafts?(G1) I'd be leery with a standard 40-

From what I understand there is some machining involved on the HT3B- perhaps someone can clarify how involved this huffer mod is.....

why not just use a decent turbo like a GT45?
