If it's a cackle car and will only be idling, then you can get away with using almost anything for a pump and nozzles. You just need to get the barrel valve set right.
If you're going to do a burnout and/or go down the track, then the next question to ask is HOW MUCH nitro you're going to run and about 30 questions from there.
If you're wanting to check out some various scenarios, feel free to sign up for the FIE web Tune-up Calculator. You can try different pumps, nozzles and percentages online and see what pressure and pills results from it. It's free to use, but you'll need to sign up and be approved. The link to request a login and then visit the tune-up calculators can be found at the bottom of this page:
