    i am planning on getting a HSW wet Nitrous Plate Kit, what fuel sys mods do i need to run a 100shot with my current mods? mods in sig. i was told to get a fuel pump booster, but they are like $300, a 255 fuel pump is like $140, can i just get a fuel pump?

    You actually don't need anything other than to make sure your timing is stock and not had a "performance tune" with added timing. I would strongly recommend buying a Walbro 255 pump which you can get for a $100.

    A baby 100 shot will more than likely be fine with the stock pump.

    I would also change the plugs out when you up the jets on the kit to some AutoLite AR-94's gapped @ .038

    You will be changing the jets out I'm sure in the near future.

    Don't waste your time or money on any type of booster.

    Your converter is also on the loose side for the bottle. . . . . . . . . . . . .
    That's my 2 cent's.

    Don't be afraid of the bottle!!! Be afraid of your tune!!!

    Put some tr-6' in. THe stock pump will probably be ok but a walbro would be a good idea. the boosta pumps are nice but if you get around 600rwhp look for something like that. another cheep alternative is a hot wire kit. you can make your own for ~$30 this just boost the amprage to the pump to 14V.

    for jet refrences.

    i agree ls2tuner. im running autolite AR-94s gapped at .038. running a 100-150shot. Nx wet kit. im getting a walbro fuel pump soon. you can find them easily for around $100 now on ebay. im also running stock timing. thats all you really need for a 100shot. also check the spark plug wires when you change your plugs. mine were shitty. i upgraded mine when i did the plugs. also i use a window switch set at 3000-6000.
