I am currently looking for 400whp. Will a 2871 get me to 400whp with a forged bottom and top end with the tomei cams? How fast would i reach full boost?

You need more injector to hit 400 rwhp.
A 0.64 A/R 2871R is right on the limit of doing 400 rwhp, sometimes it can do it, othertimes it can't. It also depends on how much boost you're comfortable with running.
As far as RPM to full boost, it's around 4000-4200 RPM on a dyno in 4th.
