Did you buy a Walbro fuel pump?Do you run an atmospheric BOV?Tell us more about your wetup.

your fuel pump probably is the issue, get a higher volumn pump.

i have a rx-7 turbo fuel pump if you are interested. it will directly bolt on the s13.

No, he said he's running rich, not lean. Not a fuel pump problem.

Krylonking, check your fuel line connections first... the return line should connect to the front of the rail; the supply hose should be connected to the hard line that runs to the back of the rail (by the firewall).

Double check all IC piping. Same crap happened to me and I only found the culprit after buying brand new Walbro pump and Nismo FPR. It was right where the piping went into the IC so it was kinda hard to see for me. It's atleast worth a check...
