Nitrous jets DIY

I drew this up from some existing jets I have and put together a drill chart of standard sizes to give an idea of what diameter to make the jet holes. It could be handy if you want something other than the standard sizes, want to do some tuning of a system, or have access to the tools and don’t feel like spending money on jets. I think there are different types of jets used in various kits, so you should double check these will work, but I believe they are the most common type. I marked and bolted in some blanks I had made and then some commercial aftermarket jets to see if they seated the same, and they did; but that’s as far as I’ve gotten testing so far. Click on the icon to the right to download the drill diameter to fuel and nitrous jet size chart, but remember it’s only a guideline. There are various formulas out there, and every application is different. Also the fuel column is currently for a 45psi EFI system, I didn’t include carbed yet. I may update that at some point.
