I would run DSM injectors. Same size and have the same clip as Nissan ones. You can also run them as O ring or trim the plastic and use a hose. It would save you from having to get an FPR and JSK fuel rail. I'd go bigger on the whole turbo but that's me. Don't use the standard turbine wheel if you want to meet your goals, stg3 min. 300 rwhp is cake at 15 psi with the right turbo. Use the 255 pump, it will easily do 500 rwhp. Some day you may want to crank it up with a little race gas. 30 psi boost gauge for when you do crank it up. Get a 4" thick intercooler if you are going with the cross flow 12x24 core. And most importantly a wideband O2 meter. LM1, PLX, ect.
