God knows there are 1000 Team Rush posts on here, and i've searched few a bunch on them but can anyone tell me any reason to use the canister vs. the e-coil for my 258?? I figured the canister coil would be easier to install since I can use the original bracket.

Also, if I am using the stock 83 ignition module with a new Centech wiring harness, will I still need the "Ford to MSD adaptor" pictured here in post #9:

I used the stock canister coil for my 258. The stock coil is as good as the e-coil at low rpm's according to Jeephammer and I agree. My 84 runs real well now after the nutter and the big cap upgrade. My engine is mostly stock and does not see any high rpms.

I run a stock coil with my TeamRush mod and the Jeep runs great.

Here is the sticky by Hammer and he does recommend the stock can coil. http://www.jeepforum.com/forum/showpost.php?p=6341476&postcount=1

if you're not running MSD then you don't need the msd connection, your harness "should" just plug into that socket, but i'm not familiar with centech's harness.

If you go and get the coil from a 1982 Ford f150 with the 4.9 six cylinder it will give you a coil that connects in to the original harness fitting and mounts to the original bracket but is physically longer and gives more voltage. It is also cheap, I think mine was about $16. Worked a treat for me and keeps everything standard looking for any visual inspection. You can also open the plug gap to the larger setting specified by Ford as well.

YOU WILL NOT need any adapters unless you switch modules to a CDI (MSD module or equivalent)...

The 'TeamRush' upgrade is all DROP ON, TUNE UP PARTS.

Just the cap adapter, cap, rotor, plug wires.

You SHOULD NOT change the coil on an I-6 engine.
You don't gain enough usable spark energy to make it worth the change over to the E-core coil.

If you want a coil that will give you slightly more USABLE spark energy, try MSD p/n 8205, it's a DIRECT REPLACEMENT for your current factory coil that has slightly better winding ratios.

If you DO decide to change the module, I suggest you use the 'Stealth HEI' idea from John Strenk.
He simply changes the guts of the factory DuraSpark module for a GM HEI module, and mounts it right in the same case. Works good and doesn't have any serious draw backs...

I used the E-Core coil when I upgraded to the larger cap. Are their any downfalls to this? I thought I read a post by Jeephammer saying that the E-Core coil is more reliable. Anyways, there would be no reason to go back to a canister coil now right? I just have some wasted spark energy?

I don't know about an E-core coil but you should definitely change the coil for something better than stock. The stock coils provide relatively low voltage, even by OEM standards, and that will not have improved over 20-30 years of use. Even a slight upgrade allowing you to run a bigger plug gap thereby getting a fatter spark is definitely worthwhile. That's why I changed my coil for the Ford 6 cylinder one, as I was basically using the rest of the ignition system from one (cap, spacer, rotor, and plug wires) and run the larger gap specified for that model of Ford. I don't think the overall performance of the 258 warrants the expense of some super dooper mega voltage coil because you will not get your money's worth in such a unit but will have the shorter distributor cap and spark plug life as a downside.

Nope should be fine with the Ford E Coil, I have a used one on my 258 also. The lower rpms have a little less performance but the higher rpms it will work just as well if not better.

I am driving mine with the Summit CDI so the lower rpms are not an issue any more. The limitation of the voltage build up and discharge is the lower rpm 500-2500 is with the stock ignition and the ford E coil.

Also consider if you have a very old coil like I did a $4 used coil and connectors is a good deal. I like they way my 258 runs, runs better than new. Thanks JeepHammer.

Actually, the factory 'Ford' coil is a pretty good coil...
I don't much trust the 'Aftermarket' and 'Discount' coils pumped out from 'China' and other places 'Off Shore' that Previous Owners (PO's) might have installed down through the years.

If you replace the ignition coil, go with someplace like MSD that still has a premium, USA made product,
Or some place like Borg Warner that still makes a quality product.

The 'Canister' or 'Volcano' coil does a better job with the I-6 engine since there aren't as many cylinders to fire,
AND,
The RPM's in the I-6 are kept much lower (more saturation time) so the canister coil will give you *SLIGHTLY* better USABLE spark energy...

Now, if you swtiched to the E-core coil, there really isn't an issue with that,
*EXCEPT*...
If you are running a stock Jeep/Ford DuraSpark type module.

The E-core coil has much faster saturation times, so more current is returned to the ignition module, and weak 'Import' or already damaged (After 23+ years of use) Factory modules will sometimes quit working with the increased load on the module.

This isn't an issue if you are using a CDI (Like MSD Module) or the GM HEI style module.
------------------------------------

If you have a V-8 engine, the E-core coil will DEFINITELY make your ignition produce more USABLE spark energy!

The V-8 fires an extra cylinder per every revolution, and the RPM range is much higher, giving less time to saturate the coil,
So the slight loss in low RPM spark energy is well worth the trade for much faster saturation times so the V-8 Can fire at full power at higher RPM's!
