I highly doubt the junkyard will be cheaper then new. Every yard I checked at were quoting me more then the cost of new ones. Then you factor in the amount of time you have to spend driving there and then searching around for the coils.
I have used both the truck ls coils and the ones from the vette. I have had less problems with the ones from the vette at up the 17psi.

I could still try and see if I can convince them that the whole coil assembly is 1 pack... Anyways I need to go to a junkyard for a lot of random stuff, so it's one of the things I have to look out for.
edit: I also want to get a built VVT head. I want to have a built, ported head and it just doesn't make sense to build anything other than VVT.

You will NEVER get that car to idle properly unless you have an ECU that has incredibly high resolution fuel pressure trims.
Best case is a return that's larger. Since the injectors always use some fuel, using the same size feed and return is fine too. Smaller return than feed is an awful idea.

still a bad way of looking at it. what you wanna see is the how many mJs it can store, the voltages it can output, and the gap it can produce.
this is how you compare coils:

I ordered the LS truck coils.
The coils:
http://www.ebay.com/itm/320907536103?item=320907536103
The wires:
All that remains would be making a bracket and wiring in the harness. The wires are 12" which SHOULD fit nicely.
So for $191 I basically got 2 sets of coils

You do know that those wires probably will not fit into the VC holes correctly. They will not seal the top and allow water in. You can order custom made magnecore wires for about $90. They have a lifetime warranty and will actually fit correctly. I would cancel the amazon order and shell out the extra few dollars for good wires.
Wrong.
You can just buy ibdividual booties feom magnecoer or whomeve. Bootie just salides onto tge wire.

I am correct. Vette has less fuel in every ifnition event than any of our boosted cars. Therefore spark reuirement is lower. .

Also let me know when you get your coils in, I will prob want to borrow a set briefly so I can test fitment with the FM Brackets.

No, no, no, no. Do not do any of this.
Smaller return than feed is an awesome way to get fuel pressure fluctuations at idle and low RPM which will wreak havoc on the driveability of the car. The return line needs to be the same size as the feed line. There is no reason to downsize it, and every reason not to.
Aluminum hardline under the car? Sure, if you like things puncturing it. Aluminum hardline is probably the most useless material on the planet for automotive applications - it's weak, impossible to flare easily, and highly susceptible to vibration and fatigue failure. If you really feel the need to use hardlines, then do stainless steel hardline, or don't bother and just run braided SS w/ PTFE internals. If you do it right you can delete 4 fittings, which reduces the number of failure points in the system as well.
Remember that with E85, there are three things that are allowed to be in the fuel system:
-Anodized aluminum
-Stainless steel
-Teflon
No rubber, no bare aluminum.

I have never once had a problem or seen a problem with an aluminum line. Never had a problem flaring one either.

Yeah I would say cancel the order from amazon for plug wires. Then once you have a bracket made and can measure the lengths of the wires, call up Magnecore. Tell them the part number for the LS coil you have, then you tell them it is going into a miata head, and then give them the lengths for each one. They will custom build them with both ends that will fit perfectly. Prices range from $90 and up depending on the length of the wires. I will assume that you won't be ordering very long wires so price should be right around $90. They said they generally get them built and shipped within a day or two. It might be slightly more then building them all yourself, but the fact that they are done correctly, and come with a lifetime warranty is worth the extra few dollars.
Also let me know when you get your coils in, I will prob want to borrow a set briefly so I can test fitment with the FM Brackets.

OR YOU CAN BUY THE USED WIRES AND JUST BUY BOOTIES. and no the bracket wont fit. These coils are fatties.
