i lost my sheet of paper lol thank you in advance

 

ok . there is no 125 shot for the nx kit for our cars. according to my nx sheet ,it shows only 50hp,75hp,100hp,and 150hp. .

here are the jets sizes for 1992-1997 f-bodies:

100 hp.....Nitrous 52 jet / Fuel 33 jet
150 hp.....Nitrous 62 jet / Fuel 35 jet.

here are the jets for 1998-2002 f-bodies

100 hp....N 52/ F 31
150 hp ...N 62/ F 33


now if there is a way to set-up a 125 hit ,let me know. I would'nt mind trying it out.

 

I'd imagine that in between the 100 and 150 would work for a 125.

So, a 57 n2o, and a 33 fuel would probably work well. The 33 fuel on the 52 n2o for the 100 shot runs a bit rich for me, so I went down to the 31 fuel. So I'm guessing that the 33 fuel would work well with the 125 shot.

You'll just have to see if they make a 57 n2o pill!

 

I'm interested in this too. Someone out there has to be running a 125 shot successfully

 

You guys are on the right track.

57/33 should work for ya.

NX does have #57 and 33 jets available. If none of the vendor can sell em to ya for reasonable (most probably don't stock them) shoot me an email, I think I still have some.

Good luck!

 

I was looking into the same thing, so I called NX today and they told me Nitrous: 57 and Fuel: 33 . The girl I was talking to said it's the same for both the LS1 and LT1. I don't know why because they are different for every other shot. And yes NX does make a 57 jet.

 

thanks guys i was trying to find out the same thing so know i can use that dual stage that i want to buy

anybody use it yet

 

I ended up using 57/31 since their jettings seem to run rich. The O2 sensor values look great with it this way. But, I am getting some KR, so I might try the 33 and see if it goes away.

 

Ok I talked to a guy at NX again today. He seemed to be a little more knowledgeable. Here's what he said. For an LS1 it's 57 Nitrous and 31 Fuel. He said you can't jet a LT1 to run a 125 shot, well you can at what was posted earlier, but it's harder on the motor because the mixture isn't right. He said it will make more power, but just hard on the motor.

 

thank you
