    I have spent the better part of this morning researching fuel system setups and I have gotten a little swamped with info... I'm not sure if I have gotten injectors that are too large for my setup or if they are too small... also I am not sure about my fuel pump either.

    My new engine build is: 92 ls block, full rebuild with pr3 pistons, pnp 98 ls head, spoon 68mm throtle body, stock intake mani portmatched at both ends, crower 403's possibly 404's (haven't ordered yet), 75 shot wet nitrous system, hondata s200 (haven't ordered yet), other misc parts that don't really concern the fuel system

    Fuel system so far: aeromotive fuel filter, 6an fuel line, aem fuel rail, accel 310cc fuel injectors, b&m fuel pressure regulator, fuel pressure gauge, 4an fuel line from fuel rail to nos fuel solinoid.

    This is in a 97 civic hatch so right now I have the stock cx fuel pump, is this adequate or should I upgrade to a 190lph or a 255lph, if I need a larger one, how do I tell which one to get?

    Any help would be appreciated, i'd rather find out now that i need different injectors or a bigger pump then when it's strapped on the dyno and I need to pay for a new dyno tune once I have bought the new parts

    Thanks

    Since you upgraded the injectors would should probably upgrade the fuel pump. At least to a 190lph.
