Bnr twins on stock setup, doable?

What are fuel options for a BNR setup if you're retaining emissions? I was thinking of going with a secondary fuel rail + 1680s/2000s or something, but heard there is a fitment issue with the ACV.. putting 850s in the primary or bored out 850s in the secondary good enough? Any issues with the bored injectors (heard maybe they aren't as 'smooth' or something as a modern unit)?
For twin turbo setups I go with the FFE fd step up kit. If you get the short height 34mm rail, you can fit ID2000s or EV14s and still clear the avc. Its a tight fit but I can get all the stock emissions and twin turbo solenoids to work. Leave the stock primaries but I recommend sending them out for cleaning/flowtesting. I would also replace the fuel pulsation damper or eliminate it entirely.
I'm having some specials on fuel components right now and would be more than happy to put together a fuel system for you.
