Guys thanks alot with all the help. So this is what I got that I need to run my desired 18 psi:

Hrc Stage 2
Bottom end engine rebuild
440cc min injectors
S-FMU
Missing link
New BOV
SAFC (only if I want to fine tune off WOT)
Possibly a upgraded ignition.
New clutch of course

Did I miss anything? Also the idea of 8 injectors sounds nice but also seems complicated (as if none of this already is). Are you able to have the extra 4 injectors come on only when in boost? That would be pretty nice. Lastly, with upgraded head work, 2.2 storker, all listed above set at 18 psi and damn near every bolt on, what would this car be 1/4 or hp wise. Again thanks for all the help.
