'Smart coils' have the igniter built in, like the 1ZZ coils while 'dumb coils' do not......OK...So bear with me..I have a couple of questions. What are you referring to as 'dummy coils'? Since this setup was designed in mind for the factory igniter is there any suggestion or has anyone figured out exactly what igniter to use with a standalone? Prior to seeing this set-up I was going to run the IS300 setup, foremost because the multiplex ignition issue is preventing me from getting a proper tune. Idle at time jumps all over the place. I actually have everything for that setup, but then I came across the 1ZZ setup and thought I was in love plus it elimnates the need for an igniter. This set-up however looks even better to me but I need to be practical. I know we all love this set-up but I need a few folks to try and give me their honest unbiased opinion on which set-up would be better for my application. Again, I'm running the AEM, FFIM and a T66 Turbo, 750 cc injectors ect. Also if I did run this setup I would go with aftermarket coils, is there a size I should get. Otherwise I would run the DG500 coils to start and just work my way up but I dont want to spend anymore than I need to.
If what sheedy126 is saying is true, this DG500 setup will cause spark blowout around 15 psi. This isn't actually the fault of the coil, but the igniter isn't providing the correct charging time for the coils. So, while this setup looks amazing, it isn't the right choice for a high hp build like yours. If I were you I would sooner go with the 1ZZ setup.
