Datsun Dreaming
Just installed the Splitfire coilpack system. WOW the car drives smooth now. This car was pretty well sorted out before, but now it drives like you'd think a stock vehicle would. I never thought increasing spark intensity could have such a large effect.
Any reason for the Splitfire over another coil brand (say MSD or whatnot)? Had been thinking of LS1 MSD coils when I went turbo again, just curious if there is an advantage of one brand over another in this case.

Splitfire advantage: everything plugs in and you only have to ground one wire.
Honestly for Nissan's you only really need one box, and that's a voltage amp. It basically takes the 12V your coil would normally run on and boost it up to 16-20V. That's what the blue box from the Splitfire kit does. The coilpacks are supposedly stronger, and probably wound differently. Even for KA's with a single coil, just wire in a voltage amp.
Here's a list of what to look for. Some are discontinued...
-Splitfire coilpack system SF-DIS-004 (SR20DET only)
-XS Engineering ignition amp
-B&M NewVolt ignition amp (the box, not the coil)
-Kenne Bell Boost-A-Spark wired to be on all the time
I've talked with customers running the KA-T's that have spark issues. Some of those guys don't know you need to gap the plugs down into the .030" range (stock is .044"). One guy did some research and testing with the Kenne Bell box and he's able to spark a .060" gap on high boost without misfire.
A hotter spark will get you better fuel economy and stronger driveability, too.

That's good information since I've heard of a lot of folks contemplating a MSD 6AL and a boost timing retard box for the higher HP KA-T applications.
I'm not surprised about people not knowing about spark plug gap. You'd have to have a strong spark to not have it blow out at the factory gap specs.
I wonder if Crane still builds the Kenne Bell boxes. Hmmm...
