Default Does anyone have Jet sizes for LS1 Fuel Pressures?

I know most jet ratings are at 6 psi or so.
I'm thinking about converting my 5177 kit to wet to make tuning easier.
But I don't want to have to plumb in a fuel pressure regulator.
Does anyone know if there is a chart anywhere that tells what jets I'd need for 58 psi operating pressures?

Also, what could I use to replace the factory bellows, that I could mount the nozzle in?

Not sure on the jet sizes. But most of the wet kits that I've seen installed on here are plumbed through a fernco 3x3 hose. You can get them at your local hardware stores.

That's what I plan to use, but I was also told that you'd need to use a hair dyer to get it to fit.

The company you buy the fogger nozzle from should be able to provide you with a jetting chart at 50-60psi. If you go with an NOS fogger nozzle you probrably be limited to about a 125 shot. If you go with a NX shark nozzle or a TNT nozzle you should easily be able to go 150.

Here's a link to the Colonel's N2O tech files. There is a jetting chart at the bottom, I've heard guys say that it's pretty accurate.

We carry a wet to dry conversion that has everything you need including the jets.
