Hey guys and gals, just want to say sorry first off. I've really been trying to keep from starting a tread on this subject. Because I know you 13b guy really hate it when people convert them to carb with a 12a dizzy. Yes, I know EFI is far superior to carb, yes I know the 13b coil setup is far superior to the 12a distributor. So a lot of you might get to this point in this thread and stop reading, that's fine. I know it's not a popular subject... So knowing what I know this should inform you that I've done the the research, I've done searching in both 2nd gen and 1st gen sections, as well as signing up on AusRotary because I hear those guys love carbed rotaries. While I do have a little more knowledge on what I need to be looking at. I'm still pretty clueless... I think I've read so many threads I'm getting the info mixed up in my head...

Here are the different options I've read about, but not really sure what all applies to a 13b.

DLIDFIS: now I know this is VERY popular to do in the 1st gens, and I understand that the OEM coil setup in the FC is basically a DLIDFIS system from factory. So not sure what I've learned from reading up on this...

Direct Fire: once again, I think this is for the 1st gen guys, using 2nd gen leading coil/igniter for a direct fire setup on the 12a.

Also read about using three J-109 igniters and three MSD blaster 2 coils. I think this is the route I have to go, but not a lot of info on it that I can find.

Anything else I'm missing here? I've got a feeling I've managed to get myself a little over worked on reading up on all these options, it's now become much more difficult to me than what it really is. I really hate to ask people to spoon feed me the info, but I'm needing help...

from what i gather over the years the best setup is 4 leading FC ignitors, on 4 FC trailing coils. wired up direct fire... what this is called and how to wire it is the research i will have to do when i acquire all the parts..

I'm guessing you are doing a similar setup then? I've still got a little bit longer before I get to this part, still in the process of doing my street port. All though I have already purchased my Atkins Rotary wrap around intake and Weber 48 DCOE.

i have a 12a turbo with a 12a dizzy that will need more spark, might as well go to the best setup. tho it woulda been easier 7 years ago when i had access to around 30 coil packs.

Nobody else has anymore info to share? Sounds like the both of us could use some hehe

I believe it's as simple as finding the 12v source/ground on the coil pack harness and wiring it in accordingly if it's an ei dizzy... Just wiring that is

How you are going to plumb in the brake booster? Don't see any provisions for it on the manifold. Im going with the same manifold/carb setup in the near future so Im curious, let us know how it goes.

for simplicity's sake my ignition setup will be 2 msd blaster coils and 2 msd 6al boxes

On the brake booster, from my understanding there will have to be a vacuum box plumbed up somehow. Or find a way to convert to manual brakes, which I would really rather not do hehe.

DLIFDIS, look it up. stock FB ignition sucks and probably wouldn't even keep up with a well flowing intake and exhaust setup.

I mentioned DLIFDIS in my first post, but from what I've understood it was an upgrade for the FB guys. Is it still true for the FC guys?

no, it is essentially keeping your stock ignition but using the FB distributor to manage it.

I have a blow thru set up and it was pretty easy setting up ignition. I'm only telling you what I have. I'm sure there are better ways to do it but I did this set-up on a budget w **** I had laying around over a year ago and it works fine. GSL-SE distributor (30* advance vs 25* on 12A) no locked timing w vacuum advance hooked up off the intake manifold. I wired up two MSD blaster coils off using the Haynes manual. It's pretty easy even if your an electrical diagram novice. MSD 6A on leading only, replacing the distributors ignitor. There's even holes for 1st gen coils in the driver side fender as u can see in the pic..

Thanks for the info guys!

Would you all say this is a pretty good thread to follow and go off of?

Or would this one be best to follow?

Ok going the DLIDFIS route, just ordered 2 coils, 3 GM ICM's, 3 GM ICM heatsinks, and OEM FB coil bracket.

Also I was thinking about the brake booster, and I'm just going to tap into the IM under the carbs and install an appropriate size fitting for the brake booster.
