SR? KA? I have no idea what you have I'm just guessing by the Nismo banner in your signature that you have a 240.......

fuel pressure regulator ? just a guess dont know much about 240's but o2 sensor sounds like a good one too also try map sensor could be throwing the fuel pressure reg off a bit? once again just guessing . good luck w/ it see u out and about this weekend?

Re: fouling out plugs ALOT!! need help.
LOL sorry to laugh right at ya but your asking me soemthing i know nothing about (nissans). I know generally when your engine is consistantly dumping a too rich fuel mixture, then your O2 sensor is needing replaced. Im not sure of the specifics but i would recommend taking yours out, and trying to scam one from antoher sr motor. try and get as close to what you have as possible. then try changing variables...good luck
