I have a HRC stage II with a fmic, greddy 3" evo cat back, greddy boost controller. I have stock internals now and I am going to install the howell kit. I plan on buying a s-afc, a missing link. ...What are the best injectors I can get....what should I replace the HRC fpr with...what should I replace the HRC fuel pump with? What else do I need to run 16+psi?

440cc or 42lb injectors will be the biggest you can go with the S-AFC(get that size). Get the Vortech S-FMU to replace the HRC "craptech" regulator....and the Walbro 255 intank fuel pump will be your best pump to buy. I think the HRC(accel) in-line will work just fine for your needs though. As far as getting anything else.....if you don't already have the Clutch Masters stage 4 clutch, get it! You also might want to pick an MSD or Crane ignition system as well. Oh, I almost forgot...make sure you have all the necessary gauges(EGT, digital A/F, and of course boost). Anymore questions :)
