At 100% duty cycle the 440 cc injectors can only support 275 hp. You will never run them at 100% and they won't make that number. Best you could see is about 260 at 90% duty cycle with 440's, maybe a little more if you upped fuel pressure. They are the limiting factor. Whatever turbo you mentioned, just sounds like something that was found on the internet. You'll need a properly sized turbo, else it simply won't fit or work with your combination. Good luck.

He needs a bigger turbo then
