Hondata vs HKS turbo kit?

I want to turbo my crx, its stock right now other then my intake. My friends dad can install it but I jest need the parts. He said I can run 6psi of boost with stock internals. Whats better for my crx....HKS turbo kit (used) untuned. Orrrrrr cheap ebay kit with tuned hondata ecu and dsm injecotrs??
