You can definitely do it cheaper if you have the know how. My first compound setup cost me about $700, and I completed it in 19 hours.

honestly your turbos will be a bit laggy with a 64/480 combo a buddy of mine had that setup and hated it. mine was laggy with a 62/475 both housings were large a 14cm and a 1.32 on the 475. you also need more fuel and possibly a programmer as I don't see one listed
