It is completely personal preference and based on power goals. Positive displacement = more low end torque, where centrifugal = more potential peak power. The 2.9L Whipple upgrade for these cars will be a huge improvement over the 1.7L if you're aiming to make over ~700-750rwhp where the 1.7 runs out of steam and keep the low end grunt, but if you're focus is more on drag racing/half mile type scenarios and wanting to make 800+whp, the Procharger will be the end-all.
