I have an NX single nozzle wet kit.

The jets for 100 shot are 52n2o/28fuel

I didn't get a 28 in my kit.

Is it ok to use a 31? that's the next closest jet I have.

I pulled my plugs after a 75shot and they are stark white.

 

Yes, but you may experience short-term problems that come from running way rich on the spray.

 

If you're running at leaset 1000 psi when you spray you should be fine. Otherwise, you will be very rich. I always run my fuel jets one size bigger than recommended. But, I only spray with a minimum of 1000 psi.

52/29 100
57/32 125
62/34 150

Jets are cheap and readily available. A dyno w/wideband is cheap insurance to verify your A/F ratio.

How much timing are you running on the juice?

 

Tuning is totally stock right now. I am waiting on HPtuners to be delivered.

Looks like 31 on the fuel side is going to be really rich.

I have an NX bottle heater and do can't really say what my pressure is for certain as I cannot look at the gauge when I spray. I'd imagine it is in between 95-1050. I will order additional jets. I just can't at this time because of the holiday weekend. It'll take me a few days to get them.

 

Every car is different, so get it on a dyno to check your AFR.
