Drivability blower vs turbos

Putting a sn95 Paxton on my Duster. It will be limited to 8psi boost. I already have it but rebuild kit is $500. For my dart I plan on a GT45
Can use a Kit like this one. But I will piece mine together

Block huggers like these.

Carb hat like this with a Speed Demon 750. People on Turbo forum already have this set up and have made 600+ hp on the Dyno
