In general, smaller compressor wheels provide lower air mass delivery (measured in lbs/min.) than larger compressor wheels, so I would not expect that the new GREEN HTA would match the larger RED HTA's output. The amount it would taper, if at all, would depend somewhat on the capabilities of the motor that it's mounted on to flow air...
Right, on a built motor I wouldn't hesistate for a second to but a .82 or 1.06 HS on it. I heard subie guys have a lot of problems with FP, I am surprised you guys don't say the same, especially with all the FP Threads I read. If it were me Id go with a GT42 Turbo with a 1.06 HS, but thats just me. If he's looking for moderate levels Id go with a 30R or 35R.
