He said he was building it. Pistons, rods, and a sleeved block (especially for an h22a) is sufficient to run 20 psi. Yes you are missing a high flow fuel pump off the list. You need to run at least an 255lph pump. Also as stated before, ditch the missing link and AFC setup. That is just fine for low boost, but you won't get far with 20psi on a AFC hack.
