Between the $500 and $1000. I'd say about $700ish, but part of that depends on how much time (and money) you invest on tuning. You can run 7 pounds without any issue and you can push it to 9 psi if you have good tuning.
I should have also mentioned you will need a boost controller, fuel pressure regulator, water and oil temp gauges, and an a/f meter.
