hi i hope someone can help me i know you don麓t have the 4g63n/t but you know nos(i hope) my problem is i have a stock intake, 39nos 20fuel jets (with 39n and 24fuel there was really no power, ithink it was too rich) and the power come like 20 hp or like 25 but not like 60hp. if i squeeze in the first gear no wheels spin ,my o2 voltage is around 0,900v till 0,930v is this ok? should i buy bigger jets or what ??? where is my mistake ??? i have mounted the nozzle near the tb,if i mount it near the mas it was more badly.! i don麓t know where the error is .PLEASE please please help!!!

Forget those for now. Jump up to a 75 shot (42N/27F) or 75 shot (41N/26F). Check your o2 voltage so you don't run lean. 0.92 is fine.
>if i squeeze in the first gear no wheels spin
Is it AT or MT? AT will not spin, MT will in first.

Be sure that you place the nozzle about 60mm from the TB. Also make sure that the nozzle is spraying towards the TB. If it is spray towards the MAS you will have little increase in power.

i have tested the sol. and they work well and i have mount the nozzle ca 80mm before the tb in tb way spraying , 43nos and 27fuel will work? make higher octane fuel a difference in fuel jet size?, i mean if i have higher octane fuel like 98oc that i must go smaller in fuel jet size? when the o2 voltage goes higher like 0,93 ,0,94 ... its going to rich right?
ps: its a mt and it will only spin on rainy days

Good. If the system is functioning correctly, then it is a matter of configuration.
>43nos and 27fuel will work?
Yes, 43N/27F is a 75-shot. It may be difficult to find those sizes. If you cannot find those, buy the 43N/28F jets. That is an 80-shot.
>higher octane fuel a difference >in fuel jet size?, i mean if i have higher octane fuel like >98oc that i must go smaller in fuel jet size?
DO NOT use a different fuel jet because you have high octane. High octane only prevents detonation. Only lower the fuel jet to correct a rich condition.
>when the o2 voltage goes higher like 0,93 ,0,94 ... its >going to rich right?
YES. 0,92 is optimal.
>ps: its a mt and it will only spin on rainy days
Yikes!
Let us know when you try those different jets! I hope you get it going!

what do you mean " a matter in configuration"? i must order the jets by n.o.s *what a fuck i hope they will send them before its getting cold" is the o2 voltage a difference to the octane? i mean higher octane ,higher voltage or doesn麓t make it a different?

>what do you mean " a matter in configuration"? i must order
I mean the nitrous/fuel mixture is not correct. That is why I am suggesting to try the 75-80 shot.
>the jets by n.o.s *what a fuck i hope they will send them >before its getting cold"
Order them from http://www.summitracing.com. Shipping is fast here in the States and I am sure shipping to Japan will be fast too.

o2 voltage will tell you your air to fuel (a/f) ratio. If you are running too lean (which will blow your engine), the voltages will be low... below 0,90. High voltage (0,94+) is a rich condition... running too much fuel. The octane doesn't make a significant difference in o2 volatge. You want 0,92. When using nitrous, be sure to use 93+ octane fuel so the fuel burns more "clean".
