400 HP possible?

My plan is to do a 3 cylinder per turbo approach with cusom fabricated intake and exhaust on an EFI. I was thinking of using Wiseco 3.425" bore forged pistons and a set of K1 4340 H-Beam Billet connecting rods. is this a reasonable build? And no, I do not plan on putting nitrous in this car. So, yeah.
