Hey guys, I've got a few questions for you. I bought my car and it had a NOS kit on it, but the solenoids weren't hooked up and I didn't have a bottle. Well, I am wanting to get a bottle for this year. The car has a plate between the TB and plenum, but it has 2 fogger nozzles in it, unlike all the ones I have seen before. The guy said it was jetted for a 175 shot, but I don't know for sure. How can I find out what it is jetted at? I only want to run about a 100-125 shot, so how should I jet it then? The motor is a ZZ4 with Bowtie phase 6 heads, high-flow base, 24# ADS injectors, AFPR, headers, flowmaster, 52mm TB, and a bunch more. Thanks for all your help.

it probalbly has two jets because one is gas and one is the nitrous. thats how mine is setup on the nitrous express kit and also on mine it came with a card that has the information on which jets you need to make with shot on the jets it would have a number and one is for gas and one is for nitrous you could find a bottle on ebay and probalbly call the people who make your kit and ask them what jets you will need to make a 125 shot..

I think you have to call NOS and ask them what size jets to use for what size "shot" you want. Then you can buy the jets from them or a local speed shop. A speed shop also may be able to help you figure out what size jets to use without calling NOS. From what I have heard the jets are very cheap.

 

For an NOS stander TPI kit here are the jet sizes they give you; 110HP is 38n2o + 28fuel for 150HP 46n2o + 38fuel.

 

Hmm..my 5151 TPI kit came with:

100HP - 55 N20, 42 Fuel
150HP - 70 N20, 53 Fuel
