CBR or AEM Pencil Coils?

I have a shiny new AEM Infinity ECU sitting here just begging to get wired in to my KA24DET in my 240SX. I only want to build the wiring harness once if I can help it, and as such I think I would like to switch to a coil on plug system just to eliminate any spark issues down the road. The problem is that my car has been sitting for almost 5 years due to a lack of time/funds and amazingly over half a decade your brain gets a bit sluggish on all of the juicy knowledge you used to have so I have some questions.

There are a few helpful threads like this one (http://www.ka-t.org/forums/viewtopic.php?t=23985) that give some guidance, but I thought I would ask a couple questions here too.

I love the low profile nature of the CBR Coils and AEM Pencil Coils. I believe that the CBR Coils are a more standard inductive type whereas the AEM coils are designed for CDI and may not produce full spark power if not driven by a CDI box, is this accurate?  Am I able to run the coils via the 4-channel coil driver?  Typically what is going to be my power limitation with this setup vs CDI?

Who makes a good CDI box for a distributorless, 4 coil setup like I want to run?  It seems that the MSD DIS-4 is an option, outside of that I am only really finding offerings from Autronic, Motec, etc.  Are my options really that limited if I go CDI?

Thanks for any help, I like so many others, have done things the wrong way or the cheap way in the past with certain parts of my build and this time I only want to do it once and have it be reliable and quality.

Yes, OEM CBR coils are

Yes, OEM CBR coils are inductive coils and the AEM coils are CDI coils that can be used inductively to about 300-350hp.  You can check out our Honda B-Series COP kit for more info on using the AEM coils with a 4 ch ignitor.  M&W seems to be the hot CDI box nowadays and yeah, there aren't too many multi-channel CDI boxes out there.

Take a look at the AEM "smart

Take a look at the AEM "smart coils" with built on igniter. Not a cop style, but should work with whatever you can throw at them, and likely about the same cost for these with wires as individual coils with an external igniter.

You can also find factory smart coils on some cars. For example, I am using Toyota 1ZZ coils on my 2g Eclipse to convert from wasted spark to full sequential.

Honda coils also are

Honda coils also are available. Used on S2000, some Acura models, and Honda Interceptor motorcycles.

Carl, 

Carl, 
Are those Toyota Denso coils part number 90080-19015 by chance?

I wonder about the Yaris

I wonder about the Yaris coils, I see some of the Evo guys are using these and I think they have better flange positioning and connector angles for my application.  I would think operationally they are pretty much the same.

Seems like the NZ coils

Seems like the NZ coils operate functionally similar to the ZZ coils, I may try this route...
