Anyone here know what is needed to run for example AEM pencil coils on an S14/SR? I have a PowerFC and you can set dwell time with it, so that's one problem solved.

But when it comes to wiring/installation, what needs to be done?

why would you need pencil coils? The OEM ones are good for like 500hp
and theres also Split Fire coil packs which are plug and play

'Cause I'm going over 500hp and going to run E85.. Lots of boost so big risk of spark blowout. Going for around 500whp this year, actually..

Go with LS1 coilpacks IMO... You can adjust the dwell time etc, and you can move them away from the heat by taking them off and running plug wires. I did it on my sr20 and it was awesome. Cheaper than the AEM also.

All hail the ls2 coils. Check my pic in the engine compartment thread. Super easy to do the wiring and they are awesome.

MSD DIS-4 will do the job to convert to pencil coils..

The LS truck coils pack more of a punch than the normal LS coils.

No reason to use pencil coils, L92 truck coils (or LS2 coils) are $75/ea or so and will do anything you need, and are easy to wire up. If you have a standalone and can adjust dwell they become even more powerful.

I usually use Delphi D585 / GM 19005218 coils, they're the ones with the heat sink on the back and considered the 'strongest'.

Define "easy"? :) I'd wager that most things are "easy" for you Jordan, but for me who hates wiring it's a different story, haha.

You get to loose the igniter, first of all. You'll need to wire in a solid power source (15A at least, fused, and triggered off the ignition) to the pink wires, ground the black and brown wires to the intake manifold (somewhere near the back, don't stack them on the ECU grounds), and wire the remaining 'colored' wires to the ECU's ignition outputs.

The most difficult part of it really is mounting the coils them selves, and going to Autozone to find spark plug wires that fit.
