Hi everyone,

 

One of my Ignition coil packs has failed and I need a new one, my Zed is running 392bhp is it best to keep the coil packs standard original Nissan part or is aftermarket ones any better if so what are the best makes out there and I maybe upping the power in the future what is the best option I have standard or aftermarket. Thanks

Unless you are planning very high boost levels stock coil packs will work fine.

Hi Andrew, do you know how much boost and bhp can the standard ones can handle, in the future I may want to push about 460bhp if I decide to upgrade the turbo's

standard coilpacks are fine.. but make sure you have/use TT coilpacks and not the NA ones.

Correct (and correctly gapped) sparkplugs are more important.

 

For high horsepower (600+) you may want to look into the HKS twin ignition amp (http://www.twinturbo.net/ttnettech/hkstpia/hkstpia.html)

Sorry for the delay in replying. I can't find the original reference from Greg@SZ I was looking for but here is the text:

 

"I have never had a issue with running as much as 8000RPM with the stock coils.

The reason you want a tighter gap for higher boost is because the plug is harder to fire with more pressure for the spark to have to jump across.

Higher RPM's requires a better coil than lower RPM's because the coil has less time to re-energize.

I have a antique coil tester that shows the spark across a gap on the machine, the machine has a knob you can turn that simulates higher RPM.

You can watch the spark go away with most single coils for American cars when turning the knob.

When you use a 300zx coil, you can go all the way around and the spark never goes away ;-) (We have 6 coils and they have 1)

I have tested really expensive Mallory coils that blow out easy.

The stock 300zx coils are amazing."

are the NA and TT coilpacks marked differently to tell the difference? sorry if its a stupid question!:blush:
