Hey Tom I'm running a NX hitman on my 2000 2.0 Zetec 75Hp shot
What spark plug would be the best for my motor.
I have a OBX header no cat and cool air intake.

Also if I run 100Hp shot on 105 octane do think it will stay together.
I mine just 3-5 runs down 1/8 track.Not daily usage.[:)~]

At least 1 step colder , AZFS22C

Your pushing it for sure if you dont have tuning for that much

Tom

I agree with Tom. You're pushing the hell out of it with 100 shot and no ignition retard, even on high octane gas. I did this and was detonating like a mofo, so I don't recommend it unless ya have ignition control. I was thinking of getting the MSD Digital SCI+ ignition box, picture here (http://www.msdignition.com/ignition_19_6350.htm) and the MSD adjustable timing control, picture here (http://www.msdignition.com/tc_2.htm). I don't know if it would work better than a chip, but that's my idea for when I start throwing a 150 shot to it. So if it works, that might be a way you can take care of the timing issues you'll be facing.

Tom or Viney, could you guys verify this setup would work?

thanks for the plug info but I just stay with 75 hp shot for now.[thumb]

could anyone tell me the output wire for the tps. so i could hook up my wet kiti have the zex running a 55 shot.
