Using a 420a coil pack?

This seems to be a cheaper option than CoP's and gives some more sparkage than the stock coil pack. I have a 1.6 and I have a question about this writeup:
http://grassrootsmotorsports.com/for...e/14115/page1/
So there are 3 wires on the 420a coil pack (1/4trigger, 2/3trigger, common ground) and 6 wires on the miata coil pack (trigger, 12v, ground). So the triggers are fine, ground is fine ... but what about the power?
Thanks for the help!

How much does it cost?
What baffles me is how simple it is to make COPs and only costs roughly 100-120 yet you guys CONSTANTLY keep finding other bullshit that's "better than stock" but STILL NOT COPs and wasting time with it.
It is not COIL ON PLUG, therefore whether it has a longer wire or shorter wire its still not COIL ON PLUG so it is not as good.
Why **** with inferior **** when you can have superior?

Well, I certianly would like to play around with different coil setups. So, when do you plan on adding some Nology to that setup?
I'd be interested in a set of MSD coils to go with mine. I have been wondering myself why people go the COP route when the wires I use seem to be very effective and require no coil modification - and to boot you can still find a better coil setup should you desire more.

superior to what? To the common plug wire?
I don't know of any COP setups that include a capacitor like the Nology wires do - so In truth, all the COP does is eliminate the resistance caused by the plug wire between the coil and the plug correct?
I guess you could try using the pulstar plugs but they're unreasonably expensive and don't survive very long from what I understand.

I think I have to argue the new/expensive cars arguement. If cars were made perfect, we wouldn't have to modifiy them
I do wonder though, given my experience with the wires I'm using and playing around with various plug gaps and modifiying the plug ground straps - I was able to achieve 40 mpg before my turbo setup.
So why aren't the manufacturers using this technology? I think sometimes they do as we do, and over look the obvious. Otherwise I have to assume they're tied in with big oil and just don't want us to have it yet.

Well, they'll require an igniter. The guy in the article has a 1.6, and those cars use an external igniter (located on the right side shock tower) and a three-wire coilpack. So he just replaced the OEM coilpack with the new coilpack.
I don't see any advantage to this. Looks to me like you're just replacing one obsolete technology with another.

Considering the 150% more voltage coming out of it and the cost (5-10 bucks from u-pull-it), I thought it would be worth it since I'm having issues keeping a stable spark in boost.
18psi: you say it's obsolete technology ... well why are you driving a miata and not the newest technologies from Porsche, Ferrari, or Tesla? Why do people still use dial-up? Why are the naval aggressors using airplanes from the 60's? Not everybody has the money to throw around. You say "just $100-120" but I spend just about every dollar I make on bills, food, rent, and school. I'm just looking for a cheaper solution to my problem and that's why I asked.

I'm a real cheap bastard myself. If there is a way to save a few bucks here and there I'll do it, even if I don't need to.
But I learned something: some things you don't compromise on. Some things you either do RIGHT, or you **** around, beat around the bush, settle for a marginally cheaper product, and in the end you either end up doing it RIGHT or hating yourself for not.
When you get ****, you may have saved a few dollars, but in the end you're left with ****.
