for a fuel rail just use a stock one, i had stg 1 srt injectors on mine all i did was figure out where i needed to shorten it cut a small "V" groove in the bracket and bent it up, worked perfect. i think lorenzo in neons.org sells them but there pricey....also as for intercooling piping custom gets expensive if you need a srt dp i assume your using a srt turbo? if so use the stock srt hot side pipes, mainly the hard pipe because it fits perfectly under the motor and will get you from the turbo to past teh front motor mount....
