I am wanting to put my NX N2O system on my car.I have the jets for 100 and 150 hp shot.I am going to put NGK TR55 or TR6's in.I was just wondering
if I will need to put an ignition box(MSD or Accel 300+)on my car to spray it with either HP shot.What are you guys running with N2O? And if I need a box which one would you do MSD,Accel 300+?

 

Go with the TR6 and consider the Mallory 685 it will give a hotter spar, handle spark based rev limit(IMPORTANT), timing retard, and window switch functions.

 

Anyone else?

 

I'm running the mallory 685 since it has all the saftey features i need.

 

Does the Mallory 685 have a wiring harness for a 95 LT1 or do you have to splice the wire in?I really do not want to cut up my wiring harness.

 

MSD Digital 6 has an adapter harness. It also has rev limit and timing retard.
