It has begun!! (MSD Ignition and Coil upgrade)

[81xsproject]

Well, I am officially underway as my 78 advance arrived the other day and my buddies KZ is officially road worthy (and quite fun). I have started taking pics, too.

But, before I post them I was wondering if the stock 4R0 iggy could hand running my MSD 2 ohm coils.

If it can't, no big deal. It would just be cool to test it out with just the coil upgrade and be able to compare that with the having them plus the new iggy in there.

The 4RO is for the 3.9 OHM coils. If you get your hands on the ballast resistor from a '78/79, that will take care of the problem. You could also pick up two automotive resisters and go that way.

Well, it's not worth that much trouble. I just wanted to see how much difference a high end coil would make performance wise.

I upgraded to Dyna coils and noticed a difference. No hard numbers, just my "seat-o-the-pants" meter.

I upgraded to Dyna coils also a few years ago. There is a seat of the pants feel to them but I do not think that a better or more modern ignition is actually a power adder. What it does do is provide a more robust and perhaps longer spark event that will unlock some power that the weaker spark will leave unused. Still, I found them well worth the $.
