I chose the rhb31/vz21 because of many reasons.
The insight is tall geared. I want boost down low.
This turbo is good for 100-900cc.
Chevy used this turbo on the Chevy Sprint.
It will make 10lbs at 1750rpm.
According to the compressor maps, I fall in the perfect spot at 10psi.
My goal is 40-50% power increase, which should be right about the limit of the turbo. The insight makes 67hp stock (probably closer to 55 after friction losses). And even at 67hp, 50% = 33 which = 100hp.
