Get siemens deka injectors off ebay new for under $500.
I'm using them in mine and they're all sweet Get at a minimum 550cc, but probably go higher for future E85 usage.
ECU one word... NIStune!!!!
Z32, Trojan has them locally, or CRD has a special on them i think?
FMIC? I used a Blitz CS return flow cooler. Fit nice and easy
