I Just bought a nx wet kit and want to keep it for those times that I just need it. I dont want to use it all the time so I want my car to remain as fast as it is now.

So im wondering if I have to use ngk6 plugs ect. I dont want to do anything to hurt my all motor performance since that what I run most of the time. I am already running pretty rich due to my headers. Last time on the wideband it was 12.1 to 12.3 will that be fine to run with?

 

What size shot are you planning?

 

On motor that is a little rich, but when spraying it is good to have more fuel. If you are going with a wet kit, I would put the next step up fuel jet in to make sure it is safe. On a dry kit you will want some tuning to make sure you are running rich enough for the N2O.

 

I will be using the 100 shot every once in a while when i go to the track and maybe keep the 50 shot in while on the highway, Just in case I need a little extra. I wont be using anything above the 100.

I have hp tuners so I can make some adjustments if necessary.

 

I believe that you're still going to have to run colder plugs. They shouldn't hurt N/A performance too much.

 

You're probably hurting more running 12 -1 a/f NA then you would be with the switch to TR-6s. That's a good safe ratio for the 100 shot though if you are going to spray it. I think you can get by with the 55s, but there really wouldn't be much loss except a few hp by switching to them.

 

yeah as soon as I figure out how to lean it up w/ hp tuners i planned on doing so.


What could be the outcome of keeping the tr55 and running the 100 shot like once every 4-5 weeks? Or just in general running them with nitrous?
