I have the EFI connection coil brackets, works great. If I wanted to get super fancy, put in the effort and make custom plug wires, I think mounting them under the cowl would look pretty sharp.

Like I said...I can design one similar to the EFI connection brackets that will fit your coils. All I need is some dimensions...

You have to use custom plug wires for the kit anyway, regardless of where the coils are mounted.
Stock LS1 wires will not fit.

That's why I sent pics of your plug wires and measurements from my old Katechs to a spark plug wire company and had them make me custom plug wires based on yours with the 90* boots. The katech length worked but the boots sucked, I sent pics of yours for refrence so they knew what I wanted on the plug boot end, since every place I tried to explain what I wanted was like wtf. Bet you didn't know I was such a crafty copy cat? I liked your 90* boots and not the junk they put on the ls1 plug wires

You should be okay with a Mail order tune with bolt ons. I'd just send it over to Speed Inc. They've got some experience with the 24x kit now.

BizZzatch, nice copy cat work! Thanks for the compliments on my wire setup. It definitely turned out better than I thought.

Yep, the truck coils are the most powerful. Here are some guidelines:

-Stay away from LS1/6 coils. They work but are the weakest of the bunch.
-While any LS2/3/4/7 LQ4/9 etc coil work, the round heat-sinked truck coils are the best.
-LS1/6 coil coils and wiring harnesses have a different pin-out at the coil plugs than all the others.
-Every different style of coil has it's own coil bracket. Don't think any bracket will work with any coil.
-The best spark plug wires to use is the Granatelli Motorsports zero ohm wires.
-The round heat-sinked coils have special dwell abilities that allow you to really take advantage of their output and need to be tuned appropriately.

Alright here are some more pictures of the poor mans route. Remember now, I'm not a show car, I really couldn't care less how things look under the hood, so long as it works.
If you want to go this route you could of course cut the rod stock down so its not sticking up, wasn't worth my time I guess.





It's sorta ugly, but it works.

They do for me!

Really, not a bad setup. Just beware of vibrations and those coils coming loose. Vibration will kill 'em.

This is a really great idea. The only difference I would make to make it look "sexy" , is to cut the studs down a bit and use the chrome acorn type cover nuts, like these:http://www.ebay.com/itm/Chrome-Acorn...-/220672664590

And you could always sand them and paint them, depending on the look you're going for.

You mean from the white C-100 plug to the little 4-pin plugs that go into the Coils is different from the rest?

Looks like it's not mounted at all. If you take a closer look at the pics, they're all cocked a bit one way or the other. I think they're only mounted on one side.

I think they're close enough to share a bolt. 4 coils, 5 bolts.
