I have the nx wet kit (100-150shot). It has all the safety stuff and I have ngk-tr6 plugs that I need to install. I just bought the msd digital 6 ignition and a new msd coil. My question is what should I gap the tr6 plugs at? Someone told me if I had stock ignition to gap at .035, but if I had an aftermarket ignition to gap at .040. Please help me on this one b/c I have no idea.

 

I have mine gapped at .038.
But honestly, you won't notice any difference between .035 and .040. So anywhere in that range will be fine on the juice or N/A.

 

I dont understand this whole gapping thing. Can somebody please explain it to me? And can somebody tell me what the best gap is for nitrous?

 

Check out this article. It should have everything you need to know...

 

according to the article my gap w/ 100 shot should range from .044 - .047. But what I want to know is what would be the advantage of using .044 over .047 and vice versa.

 

.038 works well for me....

From that article, "Insufficient spark plug gap can cause pre-ignition, detonation, even engine damage. Too much gap can result in a higher rate of misfires, noticeable loss of power, plug fouling, and poor economy." But I think anywhere in the .035-.040 range and you will be fine on and off the juice. Just remember that the gap will enlarge with time and usage.

 

I ran the NOS 5176-EO kit with NGK TR6's, gapped to 0.040", with the MSD-6A and had no problems. Currently running a 275 shot, cold Champion race plugs (684/S57YC) at 0.035", and fired by 8 individual LS1 coils. That setup was selected by the shop that tuned the motor, and so far no problems.
