I am wanting to go ahead and upragde my ignition and stuff while I am rebuilding my motor and such. I am planning on using a Jacobs FC1000 but I dont know what coils to use. I have heard of using LS1 coils but I cant find them on Summit's site. Are there any others that are any better then LS1 coils?

I know that people say that an ignition upgrade is stupid but, I want to go ahead and have it done so when I get the new motor. So I am certain that I want to upgrade the ignition system, Im just looking for suggestion on coils. Thanks guys.

BTW, I did search but I didnt find much about what coils were best.

 

The stock FC coils generally do just fine. Infact most FD owner will upgrade to the FC coils so when they upgrade to a better ignition they won't burn out the the coils. I'm running my stock coils with a mallory digital 6 ignition with no problems. It runs hotter spark than the jacobs fc1000

 

Well not to sound dumb, but what makes the FC ignition system so superior to everything else on the market? I just doenst seem logical to me that a 20 year old system (not saying it was originally bad, but its just getting old. Time basically) is better then something newer. Plus stock iginitions that I have found new or OEM or whatever are like $500 and Im not paying that for a new stock ignition system. I mean if I am dropping $500 on an ignition it had better be aftermarket, works just as good or better, and looks better.

 

well i never mentioned it was better than everything else on the market, i just mentioned that they are superior to fd coils. Why replace what isn't broken. Anyways you can run the LS1 coils, you can run 4 msd blaster coils, you can even use 4 accel coils if you want. The msd and accel will give you a much stronger spark, of course you'll also need 3 fc1000's, unless your planning on running that on the leading coils only. I'm not sure what your palnning on building if your just N/A i would use the stock coils and the fc1000 on leading. But if your building a 10,000rpm monster with a crazy bridgeport then i'd upgrade everything

 

Overwhelming positive experience. Plenty of people are running basically stock FC ignition system on high-powered engines and seeing little improvement from spending a lot of money on aftermarket bits.

 

Why would I need 3 FC1000's? I have seen 700-800hp Mustangs and Camaros running one MSD ignition box.

I know I have read that FC ignitions are superior in quality to most other ignition systems, I just am wondering why race specific ignitions arent really better then the FC stock system. Basically if someone could give me specifics I would apprecuiate it/

 

If you hook up one FC1000 to all three coils, all 3 coils will fire at the same time. Most mustangs and camaros use a distributor setup and can use on msd box. Our leading coil fires at the same time so you can use one ignition box on it. but for trailing they are separate and need to have an ignition box for each one.
Same thing would happen if you upgraded to different coils. You can run the leading together since it wouldn't matter because of the wasted spark. But the trailings cannot fire at the same time and you would need one box for each trailing coil.
You could always use a HKS twin fire which is setup to handle the rotary engine traliling split. Jacobs (the maker of the fc1000) made a rotary master ignition upgrade at one time which controlled all three coils. I'm not sure but you might be able to buy a MSD digital 7 or msd-dis 4 and set it up to run all three i think i'm not sure but then you are also looking at a $700 price just for the msd box and no coils.

 

you can use 2 MSD 6AL Capacitive Discharge Ignition. Also you can use the Turbo II trailing coil. Substitute the leading and the trailing coils from you N/A with 2 trailing coils from a Turbo 2.

 

^ care to explain that a little better? Aren't all the FC coils (leading and trailing) the same?

 

No, the leading coil is a two-post coil that fires both leading plugs together in a wasted-spark configuration; the trailing coils are two completely separate coils firing the trailing plugs sequentially.

 

The only advantage I've ever seen having my Crane box was that I could severely neglect spark plug replacement. Last set of plugs I ran for 60K. Of course the set I have now are totalled from the initial startup and tuning to the point that even the Crane won't fire them very well at startup...
