ignition coil

[theguitarist]

So my Mustang project is coming along one little piece at a time. I ordered the Pertronix II electric ignition system from CJ Pony Parts about 3 weeks ago and I'm told it should arrive in another week. Decent prices at CJ's; not impressed with their shipping time frame! NPD or Mustangs Plus next time. My question is: is it worth me dropping another $40 for the Pertronix II ignition coil (45,000 volts)? Or is there no noticeable benefit over the stock/replacement coil, which is less than a year old. Also is there any performance difference between the oil filled or epoxy coil?

When I went with the Pertronix, I used the Pertronix I and matching coil. The extra output of the coil allows you to run wider gapped spark plugs. I set mine at .045 and has been working flawlessly for well over 5 years now.

The way I see it is when you upgrade one part of a system with a performance part you really should upgrade the rest of that system. Its like if you upgrade your fuel system you really should upgrade your exhaust.
I personally do not have any experience with Pertronix II electric ignition system/coil, or any other coil. I want from stock ignition to a DUI.
Did a little research and found this: http://www.pertronix.com/prod/ig/ignitor2/default.aspx
I know that they just might be trying to sell you their coil but it makes since. I tried to find the stats on a stock coil to compair, but i couldnt find anything.
I think you should take out your stock coil and put it on ebay of some thing for half price and put the pertronix II coil in. But its up to you.

When I have done ignition upgrades I have got the performance coil also but not because I think they are better just because my original was an unknown factor and the performance ones are often in stock and about the same price as the stock ones that are often special order.

If your coil is only 1 year old i would be tempted to run with it. Its been a while since I have done a pertronix but at least with the version 1 it seems to be that even in their manual they say you can use the stock coil.

i just put the ignitor II unit in my car with the wires and coil and it smoothed out so much and ran beautifuly. I just then started to trust it to drive out of the general metro area i live around and heading down to the lake the coil failed. it wasn't filled at all the units inside were rattling (which it shouldnt do) and it was considerably lighter than the stock (not good in my opinion). i put the stock coil back on and it hesitates a little bit more and it actually seems a little bit less gutsy than it did with the ignitor coil. I called the pertronix company and talked to a warehouse manager who told me that this is the first occurance he had heard of. he pulled one of the shelf opened it and it was full.
I suppose the moral of the story is there is always one or two in a production run that have a little flaw to them. ALSO that it does make a difference to use the lower resistance coil. You can open the gap up on the plugs and it just runs generally smoother imho.

Alright, so I'll probably order the coil next week. What's the difference between the oil-filled and the epoxy coil?

Oil filled are not as vibration resistant and must be mounted nearly vertical. Epoxy can not leak, generate less heat, do not require a resistor and generally have a higher output capacity. A good cheap upgrade is to get a stock TFI coil from an 80s to early 90s fuel injected ford (junkyard is fine, very durable), with comparable output to aftermarket units.

One thing to watch for. If you have a resistor wire built in your ignition make sure to match the coil. If it doesn't require one, replace the resistor wire with a reg. wire. Coils don't like the wrong input voltage.
