So you have a ported valvetrain and diamond forged pistons + a spacer + intercooler?
I mean this depends on the tune and how much boost you plan to run but based on what I have seen on this forum it will be under 300hp.

Which turbo are you using?

The pistons, camshafts, valve springs, injectors, intercooler, and ported intake manifold don't do much to create more power above and beyond the tune. However, they do allow for the potential of greater flow through the engine, (which makes more power), IF you have a turbo that's up for the job. The factory design of the turbo/manifold as an assembly puts limits on power potential, as it is restrictive even if there are modifications to it. You can only shove so much through a tiny hole.

When I had a ZZP V3, I made around 220 WHP. See my build thread for details. I had all the engine modifications you listed plus a few more.

Okay well that's very depressing cuz I got nearly $6,000 in this engine and I do not have a turbo up for the job it's only a stock turbo for now because I cannot find a manifold to upgrade to a bigger Turbo

Can you find me a T25 turbo manifold here in North Carolina none of the shops I talk to want to make one so having trouble getting one
Howie from HEPerformance made mine. Lead time was around 3 months. He ceramic coated the manifold at my request. The quality was superb! I paid $535 for the manifold plus $170 for the ceramic coating.
