Also, I don't know which kit you are thinking of running, but If you are going to run the VCN-2000 with a turbo, you are going to need some serious internal engine work. Some of the turbo kits offered by THM will include uprated internal bits and pieces, but I don't know if they would be up to with standing "doulbe duty" in a turbo'd/continous feed nitrous engine. The VCN-2000 is a system that feeds your engine small amounts of nitrous throughout you rev band. You would be better off getting a ZEX kit since it would only activate at WOT and you wouldn't use it as much.
