Looking for new turbo

[CUMMINS01]

I have an 2006 cummins and am planning on making 550 rwhp. I was wondering if there is a single turbo that can turn that kind of power with about the same amount of lag as the stock turbo or less. Is this unrealistic or not?

If it was me I'd look at the High Tech Turbo 71 series with the 62 compressor and 13 exhaust.

A SPS6280 by Industrial Injection would be perfect for you. A bud of mine made 579hp with one. That that was also made with stock sticks and CP3.
